  • The BenQ RL2455HM, At A Glance:

The BenQ RL2455HM comes in at 24-inches of screen estate, a sweet spot for most gamers.

The RL2455HM is the latest in a series of professional gaming monitors created by BenQ. If you follow competitive gaming, you have most likely seen their monitors being used in various video game competitions throughout the world, most notably in Major League Gaming. BenQ have earned a reputation creating displays where every millisecond counts, and the RL2455HM continues this trend being the official monitor of the 2013 Major League Gaming circuit. While it is advertised as a monitor designed for RTS games, it actually functions exceptionally well for a variety of game genres, including shooters, fighters, and fast-paced action games.

 

The BenQ RL2455HM features a good amount of connectivity options, including 2 HDMI, DVI-D, and VGA (D-Sub) inputs.

The BenQ RL2455HM features a good amount of connectivity options, including 2 HDMI, DVI-D, and VGA (D-Sub) inputs.

 

As listed in the spec sheet above, the monitor features connectivity for up to 2 HDMI devices, as well as a single DVI-D and VGA (D-Sub) port. This should be more than sufficient for the majority of console and PC gamers out there, especially considering that popular monitors such as the ASUS VH236H and VH238H only feature 1 HDMI port. The monitor features 2 speakers for stereo sound, at 2 watts per channel. The speakers won’t blow you away by any means, and are merely there to provide sound. Thankfully, the volume is loud enough so if you’re going to lug this monitor around, you don’t have to worry about bringing an external set of speakers (unless you want better sound and some bass).

 

The BenQ RL2455HM features a line in to transmit audio from an external source to the monitor, as well as a headphone jack for those that want to game in privacy.

The stand and materials are very well constructed. I was especially surprised at how easy this monitor was to assemble. Simply attach the included stand by inserting it into the provided base, and slide the whole piece into the back of the monitor, locking it into place. No tools necessary, and it’s extremely quick and efficient. If you ever need to detach the monitor from its base, simply use a tool to press the “release” button the back of the stand, and remove as necessary. The red line on the base of the stand has a nice look to it, distinguishing it from the plain black look of most monitors. The monitor has a matte finish on its plastic, with the exception of the stand, being glossy. I personally prefer the matte finish as it requires less maintenance and prevents excessive fingerprints on the monitor’s casing. Everything has a great, solid feel to it.

  • Panel Specs:

The RL2455HM uses a matte TN panel with a LED backlight, which is fairly common for most monitors in this price range. TN panels are known to be very fast when it comes to response time, and the BenQ exemplifies this by offering a 1ms GTG (gray-to-gray) response time. It’s a nice touch when most TN monitors released nowadays usually max out at 2ms GTG response time. Response time governs how quickly a pixel can shift from black to white, or in this case, gray-to-gray. The benefit is reduced ghosting, which is a must for competitive gamers. Being a native 1080p (1920 x 1080) display, it can correctly scale 16:9 content (such as 720p) without any major issues. The panel features a dynamic contrast ratio of 12M:1 (million), and a native contrast ratio of 1000:1. The panel operates at a 60hz refresh rate, which can be disappointing to gamers used to 120hz refresh rate from their PC games. However, for those that game primarily on the Playstation 3 and Xbox 360, or even the newer Playstation 4 and Xbox One, the 60hz refresh rate won’t be a deal breaker.

 

  • Buttons:

The RL2455HM has some great button control. Unlike most monitors that are released nowadays, this monitor doesn’t designate specific buttons to specific menus. What this means is that you can press any of the buttons on the side to bring up the OSD options, with the menu system appearing on the screen itself. This is great for gamers that are in dimly-lit or dark rooms, as it can be a pain to figure out the right button to press on most monitors, often resulting in trial and error. The RL2455HM keeps it simple, allowing you to access its menus with relative ease. The buttons retain the casing’s matte finish and build construction.

 

The buttons have a solid feel to them, and are really easy to use.

  • Menu Items and Features (OSD):

BenQ has been using several different technologies over the years in their professional gaming monitors, which include features such as Smart Scaling, Black eQualizer, AMA, and Instant Modes. Smart Scaling allows you to manipulate how content is displayed on the screen by constraining the image to different sizes and aspect ratios. Black eQualizer essentially controls the black level of the monitor, allowing you to increase the visibility of dark areas. This feature is useful for gamers that find certain areas too dark in various video games. The Advanced Motion Accelerator, also known as AMA, is the RL2455HM’s function to control panel overdrive (affects response time and ghosting). Finally, the Instant Mode is supposed to minimize input lag to nearly-zero when enabled, functioning similarly to LG’s ‘Thru’ Mode to bypass some processing. The RL2455HM has all of these features present, so if you’re already used to some of BenQ’s other professional gaming monitors, you will find the menu systems practically identical in operation. Of course, the monitor also features the basics, such as dynamic contrast, brightness, color temperature, hue, saturation, and other picture controls. By default, input switching is buried through menus if a source is active, however the RL2455HM allows you to assign up to 3 custom keys to handle different monitor functions. In my opinion, the ability to switch inputs quickly is important, so I assigned a custom key for it without issue.

  • Viewing Angles:

TN panels aren’t exactly known to have the best viewing angles, as the gamma curve dramatically shifts when viewing from different angles. The RL2455HM is advertised to have a 170/160 viewing angle. While everything looks great when looking at the monitor straight on and at eye level, the aforementioned gamma shift is apparent when viewing from different angles. I can’t fault BenQ for this, as it’s a drawback of TN panel technology that affects numerous monitors. The 24-inch size is suited for gamers looking to play solo, so as long as you keep it at eye level, everything pops and looks great.

 

  • Black, White, and Color Output:

The RL2455HM comes with various customization options, so for gamers looking to tweak almost every aspect of their picture, you’re in luck. This monitor comes with several picture modes, including: Standard, Movie, Photo, sRGB, Eco, RTS 1, RTS 2, and three Gamer profiles. The differences between all of the modes are slight, with the exception of Eco, as it dims the backlight and over-saturates the colors. Personally, I stuck with the RTS 1 mode, as it is the factory default and can be customized. You are able to control the black eQualizer, color temperature, hue, and saturation in this mode as well. Some modes such as sRGB prevent you from making several picture adjustments, as sRGB is typically the “out of the box” mode to resemble D65. The color temperature controls allow you to individually tweak RGB values to your liking, which is a useful feature if you’re looking to calibrate the display with a colorimeter.

The black eQualizer is useful when trying to increase the detail in dark scenes without directly impacting the white level of the monitor. It does this by adjusting the gamma curve for dark gray, bringing out more detail in darker tones. Using the test images from Lagom, I took a few pictures to showcase the difference between black eQualizer set to 0 (turned off), and set to 20, its max setting.

First, with black eQualizer turned off. Notice how the top row of squares are hard to see:

Black eQualizer set to 0 (turned off). Bloom isn't from the display, just my camera.

Now, with black eQualizer turned to 20, its max setting. Notice the increased visibility in the top squares:

Black eQualizer set to 20, its max setting. Bloom isn't from the display, just my camera.

Similarly, the default contrast setting of 50 looked good enough to resolve most of the squares on the test pattern. I wouldn’t recommend exceeding this number too much unless you want eye-bleeding whites, which can be fatiguing:

The default contrast setting of 50 resolves the majority of the squares in this pattern.

Use these settings at your own discretion, as they may look different on your display.[/tab] [/tabs]

 

  • Scaling:

The RL2455HM features several Smart Scaling modes, most of which allow you to manipulate the picture into different simulated aspect ratios and screen sizes. While it’s a unique feature to have, I couldn’t really think of many applications to apply it where it would be beneficial. I suppose it’s a useful way to stretch an image that has an aspect ratio that’s not 16:9, without having it take up too much or too little of the screen. The important thing is that the RL2455HM handles scaling well with the Full and 1:1 modes, which is more than sufficient for most gamers. I don’t recommend using many of the Smart Scaling modes personally, because it disables the built in AMA overdrive function of the monitor, resulting in increased motion blur.

  • Measured Input Lag:

Designed primarily as a monitor for gamers, by gamers, it’s extremely important for the RL2455HM to offer near lagless gameplay performance. After all, it is the official monitor of the Major League Gaming 2013 Pro Circuit, as well as Street Fighter tournaments hosted by Level|Up. Using our dedicated lag testing device, which is used for all measurements in our input lag database, I tested all of the picture modes available on the RL2455HM, outputting a 1080p/60hz signal to the monitor. Interestingly, all of the picture modes offered nearly-identical values when tested with the lag tester, and it didn’t seem to matter whether Instant Mode was enabled or not (a mode designed to further reduce input lag). The measurements below were recorded under RTS 1 mode, with AMA set to High and Instant Mode enabled:

[list style=”arrow-right”] [li]Top: 3.0ms[/li] [li]Middle: 10.2ms[/li] [li]Bottom: 17.2ms[/li] [/list]

Averaging out all of the measurements results in approximately 10ms of input lag, which is excellent and in line with other near-lagless displays such as the ASUS VH236H, also known as the tournament standard “EVO” monitor. Considering our lag tester accounts for the display’s black-to-white response time in this measurement as well, you won’t have any issues using this monitor for any kind of serious gameplay, whether it’s a professional gaming tournament or otherwise.

  • Gaming Performance:

Being a competitive fighting game player myself, I also want to offer my opinion on the monitor’s gaming performance. Using Super Street Fighter IV: Arcade Edition 2012 as my preferred method of testing, it was very easy for me to adjust to the RL2455HM, offering identical performance to the tournament standard ASUS VH236H. I had absolutely no difficulty performing strictly-timed combos and links; the monitor felt very clean and responsive. I invited some friends over to run some extended gameplay sessions and they reported the same buttery-smooth response that I felt. Interesting note: I didn’t notice any additional input lag by having a 720p signal scaled up to the monitor’s native 1080p resolution using the display’s scaler. While I don’t currently have a scientific way to measure the input lag of 720p sources on 1080p displays, running the Xbox 360 at 720p on the RL2455HM felt just as smooth as having the Xbox handle the 1080p scaling. This should be great news to Playstation 3 owners that have to deal with the lack of dedicated 1080p upscaling across all games. I personally recommend using the RTS 1 mode with AMA set to High, and Instant Mode turned on.

  • Motion Blur:

The RL2455HM handles motion decently enough, but only under the right settings. As mentioned earlier in this review, the monitor features a mode called Advanced Motion Processing, or AMA for short. It’s BenQ’s version of over-driving the panel to push a faster response time to reduce motion blur, and what I suspect is the main force behind the advertised 1ms GTG response time. The AMA setting has 3 modes: Off, High, and Premium. To illustrate the differences between the modes, I tested the monitor using Blur Busters’ Motion Testing website called Test UFO (special thanks to Mark Rejhon for creating this excellent site). The results are pictured below.

First, AMA set to Off:

Second, AMA set to High:

Finally, AMA set to Premium:

As you can see from the screenshots, there is a noticeable after-glow present when over-drive is enabled, especially in Premium mode. While you can disable AMA and prevent the after-glow, the motion blur increases significantly. I heavily advise against disabling AMA, as it can be disorienting to serious gamers. When AMA is set to High, the after-glow is mild and strikes a great balance between Off and Premium. I personally disliked using the Premium setting as the after-glow was very pronounced, and was rather fatiguing to me. I feel that most gamers will be satisfied leaving the AMA setting to High, which is the factory default setting out of the box, as it handles the motion blur reasonably enough.

  • Keep up the great work Four Wude! I am a competitive fighting game player as well and have been looking for a site like this for years!

  • I m really glad there s someone acknowledging this! This is a bunch of bullshit! Don t know why TV manufactures are taking the gamers out the market. They must have been getting complaints from thousands of gamers! I do not want to game on a damn monitor. There is not TV in the market that is specifically for gaming or either addresses this fucked up issue with input lag. Why can one manufacture just grow a pair and invest in HDTV that will greatly reduce input lag. I think under 8ms would be great start!

    Casual gamers would not even notice the input lag and 9/10 would blame the internet connection but not the hardcore gamers. A lot of gamers don t realize this and TV manufactures are getting away with it. TV manufactures should acknowledge this and list input lag of all TV in specifications from now on. there are going to notice soon when all gamers are gaming on fucking monitors and there will be a bunch of outdated TVs on the shelfs.

    I Still game on a CRT TV because of this issue. I don t know want to game in a corner of my house. I want to sit comfortably on a couch/bed and game on a big screen television. I dont want to become a pc gamer becuase of this shit. I love gaming comfortably and competitively. I want to continue being a console gamer but the TVS that are out now are making it difficult for me to do that.

    So i thank you FourWude for bringing input lag to light. I already spread the word to friends and family. Keep up the great work!

    • My pleasure! There are some gems for gaming in the HDTV world, and I hope this site helps everyone in finding the perfect HDTV for their needs!

  • Thanks for this review. It is perfect timing for me. I just ditched PC gaming a few months ago for good. I blew the dust off my PS3 and have it hooked up to some Dell 24inch LCD, that was some super cheap deal 2 years ago.

    Anyhow I have pre-ordered the PS4 and was looking to get a good 24 or 27inch LCD to dedicate to the PS4. Thanks!

  • This is somewhat off-topic, but I was wondering if you were ever going to do any input lag tests on commercial displays… The types of displays that you can’t buy from your typical consumer electronic stores. Shoryuken and avsforums suggest the commercial displays have the least amount of input lag, but I haven’t seen much evidence of this.

    Do you think you could test some of these out?

    Here’s an example: http://www.amazon.com/gp/aw/d/B00BTK81EM/ref=mp_s_a_1_1?qid=1378319446&sr=8-1&pi=SL75

  • Great review… Just bought the monitor yesterday but found that the inside of the back of the monitor was rattling a bit if i shook it.I asked the dealer about it and he told me that it would not affect the performance.So any way i bought this monitor for my xbox 360, but do you think that it will work fine if i buy a ps4 and connect it to it via hdmi? What i mean is will the games look good? Also did you have a problem with the rattling sound? Thanks…

    • That’s odd, I do not have the rattling issue that you’re describing. The monitor will definitely work well with the PS4, and there is no noticeable input lag when you’re playing games. I hope you enjoy it!

  • I have to congratulate you. Your database has been a huge help in making me figure out which the best monitor is, guiding me through a buy in which I was completely lost.

    Now I have a dicotomic choice:

    After adding up response time and input lag grey to grey, as an indicator of how fast a monitor actually is, I’ve run into two monitors that the exact same latencies: Those monitors are the BenQ you’ve just reviewed and the ASUS VX238H.

    At first glance, which one would you choose for gaming, if you had to choose?

    Thanks a lot!

    • Great to hear my database has been very helpful to you! To answer your question, that’s a very tough call. I’d still like to choose the BenQ purely based on the extra 1″ of screen real estate, and I really like the menu systems on the BenQ, especially when it comes to dimly-lit rooms (there is no guesswork involved in hitting buttons in darkness). With that said, I doubt you can go wrong with either, so it all boils down to preference at that point!

  • So I’m getting a completely new gaming PC and monitor so I can record for YouTube. I was wondering if it would be good for playing and recording FPS games on the PC, such as Battlefield 4. This might seem like a stupid question, but you never mentioned FPS gaming at all in the review, so I wondered.

    • Yes, it should be fine for all of that. I’ve had no issues using the monitor in any way, so it’s hard to come up with complaints considering the price tag. If you’re okay with the 24″ screen size, then you should be fine unless you’re looking for better color accuracy (then you will have to check out IPS monitors).

  • Could you share your picture settings for this monitor? Also could someone explain to me whitch options should I choose in PS3 Display settings in [RGB Full Range (HDMI)] and [Y Pb / Cb Pr / Cr Super-White (HDMI)]?

    • On your PS3, make sure you enable RGB Full Range via HDMI, and set your black level to full as well. You want to send RGB ranges to your monitor and NOT YPb/CbPr/Cr. The latter is used mostly for HDTVs.

      I didn’t deviate too far from the default RTS 1 settings, but here is what I used. Keep in mind these aren’t meter-calibrated settings, and just eyeballed using test patterns:

      Picture Mode: RTS 1
      Brightness: 100 (controls backlight, depends on room lighting)
      Contrast: 50
      Sharpness: 1
      Black eQualizer: 0
      AMA: High
      Instant Mode: On
      Overscan: OFF
      Display Mode: Full
      Dynamic Contrast: 0
      HDMI RGB PC Range: (0~255)
      Smart Focus: Off

  • Hi, first of all thanx for the review, I’ve found your article very useful and explicatory. Just want to make you a question, can you please suggest me some good settings for gaming with a PS4 and this BenQ monitor ?

    • These are the settings I use currently, though they aren’t professionally calibrated, just eyeballed with test patterns:

  • Hey Adeel! Thanks for the review!
    I just got this monitor yesterday, and after being stuck with the 2007 Samsung SyncMaster 931BW, I’m thoroughly impressed with the appearance, the matte finish of the bezel, the size, and the resolution! The blacks and grayscales are also a heckuva lot better than my old monitor! 😛
    I did notice and was disappointed however in the text ghosting, that’s a huge pain in the butt that the SyncMaster did not have (mind you it was 19″ and 1440×900). Guess I’ll just have to get used to it.
    Also I’ve noticed that in really dark scenes, there is a very slight pinkish tinge on the bottom and an equally slight greenish or yellowish (or maybe it’s just white) tinge on the top.
    Is this just an after-effect of the LED lighting? I thought LEDs were better than this! Mind you, the black levels are definitely darker than without LED so I dunno. Guess I’ll have to wait until OLED monitors become commonplace before I can have black levels where it looks like the monitor’s off. (The 4K OLED TVs are like that apparently.)

    • The motion clarity did have some issues in my review, and unfortunately, the best compromise is having the AMA set to high. You can notice it in test patterns, although it’s harder to notice when you’re actually gaming.

      I’d say the variance in tint you’re seeing sound like the shortcomings of a TN panel, more than anything else. Does the tint change/disappear when you move your head around?

      • The tint actually gets worse when I move around, but I think you’re right about the TN panel causing it. There was an IPS monitor at the store I bought this one from, but it had either a 7 or 8 ms response time, which, when compared to 1 ms, is far too much for my purposes.

  • Hello Four Wude

    I wanted to do an emergency consultation and think you can help me with the question I have right now …

    What is the best way to run a stream without having lag problems??
    Right now I use the avermedia C875 and BenQ RL2455HM

    Thanks for your help me to know the truth urged to give the best experience with respect to streams, especially in fighting games
    Cheers

    • I don’t have experience with the C875, however I’ve heard that the AverMedia LGP offers a lagless experience when streaming. May want to look into that if you’re having issues. I know it’s a popular option for FGC tournaments.

  • Hi, I just bought this monitor last week. I have a problem with his monitor. I just feel like the screen keeps beating and it hurts my eyes. Should I return the monitor or just because of my setting? because when I sets standard, the beating would be better than on the setting RTS1.

  • looked everywhere over the internet for this specific monitor to work with my ps4, and i must say your review helped me…i just bought it for my ps4, hoping to get a great responsive time with a good picture…i applaud you good sir, thank you.

    • These are the settings I used for this review, just basic calibration done with test patterns:

  • I am thinking about getting this monitor, but I would rather buy a 27″ because I am sitting like 3-4 feet away from it. I am gonna use it for my PS4 mostly for FPS. So my only alternative so far is the Asus VS278Q. Any Opinions on that one?

    • Hi Adeel, I hope you can answer this too. I play Blade & Soul MMORPG, I want to buy a new monitor wondering if I should grab the VS278Q or RL2755HM, some people are saying the Benq has crappy colours compared, thanks in advance!

  • Adeel. I have searched all over for a decent review on this monitor and this is by far the best out there. Thanks so much for taking the time to put this together.

    I got this monitor specifically for COD Ghosts on XBOX360. I will probably get the ONE but one hurdle at a time. I have been messing with the settings for a few days now and can’t seem to find anything that I really like. If you could help me with the basics of what i should be shooting for, no pun intended, I would be most grateful. Below are a few of the current settings.

    I think the i am currently on “gamer 1”. Do you still recommend RTS settings for FPS games?

    I have the black equalizer on and rather high.

    Brightness is at 70

    I have no idea what to put the saturation on.

    Everything else is kind of a shot in the dark…

  • Someone please answer ASAP. I want to buy a monitor for my PS4 and PS3 gaming. Right now my choices are between the ASUS MX239H and the BENQ RL2455HM. I play a lot of FPS games, but I also really enjoy games with good graphics such as Uncharted, Tomb Raider, and God of War. I also watch a lot of Blu Ray movies. Will the BENQ be able to deliver a good enough picture quality? I’m not sure if the picture is actually bad or if people are overexaggerating and it is pretty good. Please help, thank you.

    • The speakers are adequate, but not amazing. They are good enough to provide sound in a contained room, though using them in a larger room with ambient sound may not be the best idea.

    • General PC usage is just fine, as long as you’re not picky about color accuracy and gamma shifts. TN monitors will exhibit differences in quality when your head shifts slightly. Just make sure your sharpness is set accordingly (0 for native 1080p content).

  • Hello i had question about the AMA functionality: Does AMA only reduce the motion blur or does it also reduce the input lag/response time? Or does it reduce the response time to reduce motion blur? Anyways when turned off i understand you have more motion blur, but do you also have more input lag and a higher response time or do you have more input lag because of the motion blur? If yes, how higher would the response time be and is it noticeable? And that afterglow is called (reversed) ghosting right?

    • AMA only reduces blur. It doesn’t affect the input lag of the display, though the increased blur can cause you to react slower, as the panel is responding slower than it should. So it can indirectly affect your own perception of lag.

      The afterglow is a product of panel overdrive, which is what AMA does. AMA enables overdriving of the panel, which is what reduces blur, but can also cause artifacts that trail fast moving objects if set too high. This is why I don’t recommend the Premium setting. The High setting on this monitor is just fine, though.

  • Hello, I have a serious problem. I just bought this monitor because I thought I would get an absolute difference in response time thanks to his 1ms, as compared to the standard monitor I had before. But I was much disappointed when I saw the results. I thought AMA would do that the image was 100% smooth even in the Premium option, but instead I see a trail behind the objects moving at high speed … FInally I turned AMA off, althought you recommended not to do that. I understand that with AMA turned off I do not have any benefit of 1ms response, right? What is the benefit of having clear images with AMA High if there is a trail behind them? As I see, these shadows behind moving fast objects are less visible when i turn off AMA. is there something wrong?
    Thanks!

    • There is nothing wrong. Unfortunately, the RL2455HM is about as good as you can get when it comes to motion blur. There will always be some kind of blur present. Setting it to Premium will remove most of the blur, but there will be artifacts. Turning off AMA will result in a lot of motion blur. Your only other option is to look into Lightboost monitors and perform the Lightboost hack.

      • Hey! After using it for a while longer I’m not so disappointed as I was when I used for frist time, but…

        So I Understand that RL2455HM, by now, is not the best gamer choice if you want absolutly clear images… the problem is, that there are not best monitors at “cheap” price like that one… Which one would you buy for 160€ ? I have two questions: do all 1ms response monitors have the same amount of blur with AMA set in High, for example, or is actually AMA a way to imporve that in comparation with other monitors with same response time? (I think that AMA is only a n attempt to improve the standard features of most comercial monitors but is partially a fail…)

        And, are that artifacts, ghost’s (as you want to name..) always present in 1ms response time monitors or it is strictly an afterefect of AMA?

        Thanks for the response! It’s useful 😉

        • Almost all 1ms monitors use overdrive to achieve lowered motion blur. AMA is just BenQ’s marketing term for it, ASUS use a different term called Trace Free. For your budget, the BenQ monitors are probably the best you can do. Anything better will require a 120hz+ monitor, and those monitors start around $400 and up. I just did a full review on the XL2720Z, which is BenQ’s 144hz monitor that has a strobing backlight to reduce motion blur. You can read the full review here:

  • Hi Wude, I need you again!
    I use this monitor with a ps4 (hooked via HDMI) and I need some help about the video output settings in the ps4 menu.
    I use “Full” range for the RGB option (cause monitor is set to 0-255 range) but I don’t know if I should set to full also the ycbcr/ypbpr option. Same guess with the deep color output, should be turned off or on/automatic?
    I use your suggested settings for this monitor on the ps4 (except for brightness wich is 75) but I got some washed out colours with some games (especially on dark scenes and in some pre-rendered in-game footage). Hope you can help me cause I’ve searched everywhere and I can’t get a solution!
    Thanx!

    • If the monitor is expecting 0~255, set the RGB Range to “Full” and try leaving the Y Pb/Cb Pr/Cr Range as “Automatic”. Do not enable Deep Color, as this monitor does not support it. Switch it from “Automatic” to “Off”.

      A washed out image may occur due to the nature of the TN panel. Achieving deeper blacks usually require a VA panel, as they are known for their black level. You will more than likely have to reduce your Brightness setting to increase the black level. You can use the Lagom site linked in the review for test patterns to calibrate the black level accordingly.

      • Thanks again for your time Wude, I’ve tuned down brightness a little bit (around 65/63) and colors are now pretty acceptable.

  • Hi! I bought this monitor and i have a problem. I want to connect it to my PS3 by HDMI (only), but it doesn’t recognize it, i only see black screen and a message “hdmi no signal”. I try out all: press ps3 on button until listen second hoot, change differents cables, try with hdmi-vga cable, change settings on ps3… but anything works. I will contact with technical assistance of Sony and Benq, but i don’t know what they tell me.
    Can someone help me, please? I’m in despair!
    (I’m sorry, my english is awful i know)

        • Hi, i just got this monitor and hooked it up on my PS4, i could only get a grey screen with no video, but i did get the ps4 audio with every button press. Weird i know.

          So i tried hooking my laptop via HDMI also(tried both VGA and HDMI), worked just fine.

          i’m suspecting this has to do with resolution. I tried pressing the power button until 2beeps method, which switches my ps4’s resolution to 480p, i got the audio output, but video shrunk to a little rectangle grey box of the monitor.

          Any suggestions on how to configure my ps4?

    • Nvidia Surround should work fine. Just make sure you have HDMI/DVI connections available on your graphics card, as this monitor does not have DisplayPort.

  • Hey Four Wude. I bought an Asus VS228H monitor for gaming on my xbox one thinking that it would be lag free, it is not at all. Very noticeable and hard to play games like halo. I was wondering if this benq plays like it is lag free. People have said this monitor plays like a CRT and I can’t stand input lag. Is the input lag noticeable at all? I have a great perception of input lag.

    • I haven’t tested the VS228H specifically, however I’m surprised you’re noticing input lag. Most ASUS TN monitors tend to have very low input lag across most model ranges. You can try the BenQ and see how you feel with that. The RL2455HM is an excellent gaming monitor when it comes to low input lag.

  • I want to connect my PS3 with a HDMI cable to this monitor, but when i
    have power and the HDMI plugged in and i start my PS3 the monitor only
    gives a black screen and says something like no cable connected. The
    HDMI cable is fine, it works on my other tv, but is it just that i can’t
    connect with only a HDMI cable or am i doing something wrong?

  • Hi Four Wude i am on xbox 360 and i use a elgato will this affect the input lag or response time i really like the look of this monitor but don’t want to regret buying it thanks

    • 1 should be too low. I updated this review with calibrated picture settings; feel free to use them and let me know what you think!

        • I feel that Black eQualizer degrades picture quality. You should only use the setting if you need it for some kind of advantage, such as seeing people better in dark areas in a game like Call of Duty.

    • Every picture mode on the RL2455HM yields nearly identical input lag performance. You should notice no difference in latency.

  • picture quality score is 7 ?? it means this monitor is bad ?? :/

    everyone talks about gaming not about movies.

    i want a monitor to play Full hd movies ,PC and Console gaming ?

    so should i buy this monitor?

  • Looking to buy a monitor for gaming on my ps4 and xbone, I don’t really have a maximum budget and I can’t decide what to go for. Would this be the most recommended one or is there better in terms of image quality and low lag? I’m located in the UK.

  • Loving the picture and loving the monitor but there’s one thing I hate about it.. The AMA makes it have the ghosting looking thing.. And it distracts me as much as it turned off.. What can I do? At this point kinda regret buying this monitor 🙁 is it just a defect or what?

  • Is there any way to make this monitor work at 75hz? I’m thinking on buying one of this because of the specs, but if the panel is capped at 60hz it’s a no no. I’m looking for 75hz @ 1024×768. If any of you own one and a nvidia card and you can’t find any 75hz res, Try to create a custom resolution Thro nvidia control panel.. (1024×768 @75hz)

  • Grabbed this monitor, was on sale and needed something badly. Previous monitor had intense ghosting, this one doesn’t. However, I’m getting intense colour banding and It’s extremely noticeable. Not sure if I need to replace or can it fixed.. It’s disgusting.

  • The shop.benq site has these refurbished for $180 right now. Use the 2015gamer$40 coupon code and get it for $140! Four dollars and some change for FedEx shipping special going on too. Bought mine yesterday. I’m sure they’re just as fine as brand new. From what I’ve read most were used like once for tournaments or display, some “open box”.

    At this price; who cares??

  • Is there much difference between this and the newer rl2755hm? Trying to decide if its worth the extra money for just 3 more inches

  • I m an pc gamer not an console,i mostly play cs go and watch lots of movies should i get this or dell s2415h ips monior?

  • My display does not fill up the whole screen; it is 21″ though it should be 24″. Also I am unable to use HDMI2 which I tried connecting alternately to my TV set top box and the computer. HDMI1 works fine with both the computer and TV. Can anyone help with these problems please. The manual on CD did not help. Thanks.

  • Getting one of these tomorrow. Really appreciate the detailed review, calibrated settings, and your helpful responses to other readers. Thank you!

  • Hi guys!
    I have a problem with my benq rl2455hm. When im playing CoD black ops 2 on my xbox 360 IT has Very bad picture, The picture is pixeled. Please anyone who can help me

  • Hey, Adeel Soomro is this monitor wall mountable? Can I remove the back panel and connect the monitor with a mount stand?

  • When you switch between standard and RTS mode the monitor refreshes
    itself, is the response in both settings the same or is the RTS mode the
    proper game mode?

    Just wondering because from the original settings you first advised are in RTS mode compared to the calibrated ones in standard.

  • Hey, i have this monitor for like 3 months now and it worked perfectly. But now i have a problem. The tv gives me a signal thats HDMI no signal. I tried other HDMI but nothing worked. My ps4 is nothing wrong with so i thought maybe you had some tips or tricks to solve this problem. I cant play on my ps4 and cant use my monitor now. 🙁

  • The glow from AMA is killing me with this monitor, it’s so obnoxious and distracting. Even just scrolling through webpages it’s always in your face.

    I really regret buying this thing:(

  • Hi, I need help in this monitor. Every time i turn off the monitor, its default setting always goes back. Example, i choose my user defined settings, when i reboot, turn off then on the pc or the millisecond screen blackout when entering a full screen game……monitor settings goes back to its factory/default settings………….. so, i will navigate again to my user defined settings.. I doesnt save the last settings I used/chose. Hope you get what I want to say point out. Dont know if it is supposed to be like that or it has software or motherboard something problem inside. Please reply. Thank you a lot!

  • So my monitor was working fine until I opened it just now, I noticed that the screen is darker than usual. i tried adjusting the brightness to 100 but still the screen is darker than it used to be. I tried resetting the monitor; it didn’t work. I use the monitor mainly with my PS4. Can somebody help me please? Thanks!

  • Hello, I am having a problem choosing the best setting for this monitor. I am having this monitor and I used it mainly for:
    50% web browsing and working (ms. word, powerpoint, excel) and

    50% gaming (rocket league, team fortress 2).
    I do everything with my PC, I don’t use consoles. My GPU is MSI GTX 750ti 2GB and my CPU is Intel i3-4160 3.6 GHz. Could you suggest the best setting for my needs?Thanks very much.

    • After updating the monitor’s driver from the manufacturer’s CD and using the calibrated settings mentioned in the article, my monitor looks much better now. I wonder if the problem was the driver all along??

  • I have a Xbox one and I have this BenQ monitor I don’t care for graphics I care that I have fast response time and it run smoother should I change the color space in the setting on the Xbox one to pcrgb or leave it on recommend to make it have better response time???????

  • The calibrated settings look pretty decent on this monitor, one thing i don’t understand is the 20 brightness, it looks so dim and dark, i actually raised it to 70. Why did it calibrate to 20 brightness?

    • This brightness setting is for dark rooms. If you don’t have a dark room, feel free to raise the brightness to whatever is comfortable. Black level will be sacrificed a bit as a result.

  • Hello! in order to get the correct calibration I’m trying the settings you posted here
    but….do I have to combine OSD settings with icc
    or icc you posted should be used with unmodified standard profile on the monitor?

  • Hi, using the settings on Xbox One. On the Xbox calibration you can’t see the closed eye on brightness, nor can you see the sun on contrast.

    Also if I open the Lagom page you have used, on the black level all I can see is the bottom row of boxes and on the contrast page I can only see the first square.

    Changing the RGB’s to limited and standard show the same, apart from the contrast sun on the Xbox calibration is visible. The only way I can see all the Lagom black level boxes is leave the xbox on standard RGB and put the monitor on full, but then its not matched so its washed out.

    Is something broken or am I doing something wrong? 🙁

  • Your review was amazing, it was very usefull to me in order to get a good monitor to play games/competitive games in my Play station 4 and my xbox 360. Thanks for your work and keep doing at well.

  • Hi on ps4 pro cod ww2 looks much better on movie mode then RTS1
    Does that add lag? can you tweak rts1 to look better then movie mode?
