  • The BenQ RL2755HM: At A Glance

The BenQ RL2455HM was my first formal monitor review on this website. Designed mainly as a monitor for console gamers, the monitor did exactly what it needed to: provide a low latency gaming experience at an affordable price. The RL2755HM continues the RL2455HM’s legacy, with a larger screen size and redesigned stand. Lets see how it holds up once we put it through its paces.


Input connectivity is similar to the previous RL2455HM, offering a single D-Sub, DVI, and two HDMI inputs. This should be more than enough for most gamers, although DisplayPort is absent. Considering this is a 1080p monitor, the higher bandwidth of DisplayPort is largely unnecessary. There are two 2W speakers provided for basic stereo sound, as well as headphone and line-in jacks for your audio equipment. The most noticeable improvement to the RL2755HM’s aesthetics is the brand new stand. It’s considerably wider and heftier than the flimsy one that was fitted onto the RL2455HM, and is a welcome change. The stand is capable of tilting vertically, however pivot, rotation, and height adjustment are not possible. It is therefore necessary to find an optimal position for the RL2755HM to maintain eye level with the center of the screen. A clip for cord management is attached behind the stand to route all of your cables neatly. The RL2755HM retains a matte-black aesthetic throughout the monitor, which allows the monitor to blend into almost any environment.


  • Panel Specs:

The BenQ RL2755HM features a 1920 x 1080 (1080p) native resolution, as well as a 60hz refresh rate. The panel used in the RL2755HM is an AUO M270HTNO TN panel, which is mainly designed to achieve the lowest response and latency timings. The response time is advertised to be 1ms GTG, a standard among most gaming monitors on the market. The 16:9 aspect ratio displays widescreen content without cropping or overscan. The native contrast ratio is stated to be 1000:1, with a dynamic contrast ratio of 20M:1. Finally, the panel is capable of producing 16.7 million colors, with a color gamut of 72% NTSC.


  • Buttons:

The BenQ RL2755HM features a classic set of physical buttons that have now become standard on most of BenQ’s monitors. They can be reassigned via the OSD to serve different functions, and are perfectly acceptable for night time usage, as the functions are displayed on the screen itself. I encountered absolutely no issues using the buttons on the RL2755HM; they provided a consistent experience.




  • Menu Items and Features (OSD):

Not much has changed regarding the menu system within the RL2755HM. Pressing any of the buttons brings up a selection menu that accesses your custom keys, as well as the menu settings. The menu settings contain various options to configure your display. The “Picture” menu allows you to configure Brightness, Contrast, Sharpness, Color Vibrance, Black eQualizer, Low Blue Light, Gamma, Color Temperature, Hue, Instant Mode, and AMA. The “Picture Advanced” menu allows configuration of Picture Mode, Senseye, Dynamic Contrast, Overscan, Display Mode, Smart Scaling, Color Format, HDMI RGB PC Range, and Smart Focus. The “Audio” menu allows you to set the volume and mute functionality of the built-in speakers. Finally, the “System” menu allows you to configure OSD layout, set custom keys, change inputs, and acquire various information about the signal being sent to the monitor.




  • Viewing Angles & Uniformity:

The BenQ RL2755HM houses a TN panel, which is best suited for low response times and input lag, however it can fall short when it comes to viewing angles and color reproduction. When compared to other TN panels however, the RL2755HM offers an overall great viewing experience. I calibrated the RL2755HM to a luminance of approximately 120 cd/m², which is a comfortable backlight level for darker rooms. The RL2755HM showed the highest deviance in backlight on the top left and right parts of the screen, with a maximum deviance of -17 cd/m² on each corner. In terms of white point, the largest deviance from the center of the screen is on the bottom left, with a color temperature rating of 6635 K, over the measured center white point of 6497 K. This difference is not noticeable to the eye, and overall, the RL2755HM keeps a rather uniform picture across the screen. It is important to note that the white point listed in this screenshots was achieved without the use of an ICC profile. The RL2755HM does a great job at achieving close to 6500 K color temperature without the use of one.

  • Black, White, and Color Output:

The BenQ RL2755HM has a host of picture modes to choose from, including: Standard, Movie, Photo, sRGB, Eco, FPS, Fighting, RTS 1, RTS 2, and three Gamer profiles for further customizations. Featuring several picture presets is a standard practice for most monitor companies, however the majority of them will feature various inaccuracies that will degrade the overall picture quality. I found that the “Standard” picture mode was the best one for the RL2755HM, as it allowed enough customization to tweak to my liking. I was also able to calibrate this picture mode to achieve 6500 K color temperature. The brightness setting was reduced to 27 in order to achieve close to 120 cd/m² for dimly-lit environments. The contrast setting required no adjustment, and was left at its default value of 50, and I was able to discern all squares on the black level and contrast tests featured on Lagom’s calibration site.


RL2755HM Gamma Curve (No ICC Profile)


Once properly calibrated, the BenQ RL2755HM looks excellent for a TN panel. The default gamma value of the RL2755HM using the “Gamma 3″ setting (without ICC profile, pictured above) is approximately 2.13, which is very close to the 2.2 gamma standard used by mainstream media. The adjustments made by the ICC profile result in an average gamma of 2.48, which is more preferable for general monitor usage. Using the ICC profile below, I was able to achieve a very low black level of 0.11 cd/m², as well as a contrast ratio of 1100:1! This actually exceeds BenQ’s advertised contrast ratio, which was 1000:1. As long as you maintain proper eye level with the monitor, the RL2755HM offers a very enjoyable picture for a 27″ TN monitor.

Note: These settings were achieved using an i1 Display Pro, along with X-Rite i1 Profiler and BasICColor software. The GPUs used on the test computer are Nvidia GTX 970s running in SLI configuration, using stock settings. These settings require an additional ICC profile for accuracy. Use these settings at your own discretion, as they may look different on your display.[/tab] [/tabs]



  • Scaling:

The BenQ RL2755HM offers all of BenQ’s signature scaling options made famous in their RL and XL monitor lines. Not only can you select from Full, Aspect, and 1:1 scaling, but you are also able to emulate various screen sizes, simulating 17″-24″ screen sizes, as well as a variety of aspect ratios such as 4:3 and 16:10. For most users, engaging the screen size emulation will be largely unnecessary, but it’s a good implementation by BenQ regardless, for those that are picky about their scaling options.


  • Measured Input Lag (HDMI):

BenQ’s RL and XL gaming monitors have been known for their very fast input lag ratings, allowing the quickest input response possible from a LCD-based display. The previous RL2455HM fared excellent in this regard, offering an average 10ms input lag, which made it a formidable gaming display. The only downside to that monitor was its screen size, requiring you to sit rather close to fully enjoy it. The RL2755HM tackles this with its significantly larger screen size. But does it offer the same low input lag ratings as other BenQ monitors? Yes, it does.

Using a 1080p/60hz testing signal, I tested the RL2755HM to measure the amount of input lag present in the display. Input lag numbers didn’t change at all when utilizing different picture modes, and also did not change by changing the “Instant Mode” setting. Typically, this setting can reduce input lag, though I’ve found it to make no difference in some of BenQ’s models. The RL2755HM is one of those models that don’t require “Instant Mode” to achieve the lowest possible input lag. The input lag measured on the BenQ RL2755HM is as follows:

[list style=”arrow-right”] [li]Top: 3.0ms[/li] [li]Middle: 10.2ms[/li] [li]Bottom: 17.7ms[/li] [/list]

As expected, the BenQ RL2755HM continues to offer low latency similar to previous RL and XL monitors. The average input lag of the BenQ RL2755HM is approximately 10ms. This is fast enough to serve any gaming activity, including competitive gaming at the highest level.



  • Gaming Performance: HDMI

To further test out the gaming performance of the BenQ RL2755HM, I booted up my copy of Ultra Street Fighter IV, my preferred latency testing benchmark. I switched back and forth between the older RL2455HM and the RL2755HM, and couldn’t detect any difference in terms of input response. I was able to perform the hardest combo links, and my timings felt identical across both monitors. The use of a TN panel also helped in keeping motion blur to a minimum, thanks to the 1ms GTG response time featured on the RL2755HM. Once set to calibrated settings, it was a joy to play on the RL2755HM.


  • Motion Blur:

The use of a TN panel allows the RL2755HM to achieve very fast response times, which consequently reduces the appearance of blur trailing moving objects. The majority of BenQ’s monitors I’ve come across benefited by keeping the AMA setting set to “High”. The RL2755HM is no different in this regard. Setting the AMA to “OFF” results in noticeable motion blur that is quite distracting. The default setting of “High” removes most blurring and does a good job at maintaining a balanced picture. Setting the AMA to “Premium” results in the most overdrive to remove blur, however it creates very noticeable artifacts that degrade picture quality. I’d recommend staying away from “Premium” unless you really need the extra clarity, as it comes with a noticeable cost. The videos below showcase the differences between all three AMA modes.

    • I feel that picture and build quality is MUCH better on the RL2755HM. Input lag and other features are mostly similar.

      • So i bought the 24 and am thinking about returning for the 2755…is there a noticeable difference in picture quality? I’m just not happy with pic quality compared to my 60″ tv…input lag is very noticeable on the monitor but i’d like a good balance of input lag and great picture quality. Thanks

        • So did you buy the 27 one instead of 24 one? Which one has better picture quality? I am mainly going to use for PS4

      • I can’t decide between this BenQ RL2755HM and BenQ RL2460HT, which one has better picture quality?

        If the 24” is smaller it should look slightly better for pixel density right?

        Then why do you say the 27” picture quality is much better than the 2455HM? Is it the same for the 2460ht?

    • The settings I posted in the review are universal to all sources, including PS4. Make sure you set your RGB range to Full and set the monitor to RGB 0~255.

      • I find that the colours look better with HDMI RGB 16-235, i just wanted to know the difference between that and the HDMI RGB 0-255

        • If you set your monitor and console to 0-255 it will look way better. running 16-235 on a console and 0-255 on a monitor is not going to look better. Just make sure both are running at the same level.

          Plus make sure you reset the games gamma and video setting after getting a new monitor or tv. its not just the screen that needs calibrating but the game also.

  • Hi Adeel, picked this up for my consoles on your recommendation, it’s a fantastic monitor especially for Destiny on Xbox One – a game in which I’m a fairly serious player. Can’t wait for God of War 3 remastered on PS4 it will be unbelievable on this monitor. Coming from an 8 year old LCD TV I didn’t realise how badly lag was effecting my gaming. Thanks for the great site!

  • Looking for the best tv/monitor for gaming on my xbox1. budget of 800.00. First person shooter is what I play most(Destiny).

    • If you’re looking for the lowest input lag, then monitors will be your best choice in this regard as no TV yet has offered lag around 10ms. Do you have a screen size preference? It’s hard to recommend without knowing how large you want it.

      • if i use the 27″ on the 24″ scaling option, does this reduce the resolution? Or does it stay 1920 x 1080? I had someone say it can’t stay the same, but it says that the scaling is the same, what is the truth of the matter?

  • Are there any differences besides the panel size over the rl2455hm? Trying to decide if its worth the extra $$$

        • the pc’s will be able to run the maximum amount of pixels while most new gen, new game consoles wont be able to. both because of gpu processor speed and vram (another words the definition will look worse the larger screen size you get)….. but in reality just get whatever size you want. How far you sit from the screen effects alot aswells

          • This^ Although i am interested in seeing how the new Xbox one scorpio and Ps4 Neo perform when theyre released. Hoping we can actually have some 4k console gaming.

            Edit: Although there would be no point in doing 4k gaming with this monitor lol

          • Most ps4 games run in native 1080p, but yeah, some are not full HD, especially on the xbox one. But the ps4 pro and xbox one x easily guarantee a 1080p+ resolution.

  • Hi, i buyed this monitor for pc(i dont have a console, and i will not buy an console).
    Do you recomand it for pc (gaming : league of legends, mmorpgs)? i like the profile that u give.

  • i have a problem with it, after a period of time i got eyestrain(let’s say on webpages).
    i stay about 2 meters distance.
    i should change it or the problems is that it’s too big.

  • Go to the BenQ website it specifically states this model is for console gaming the XL models are for the PC gamers.

      • Np, I’m actually doing the reverse right now trying to find a solid gaming monitor for my Xbox one, but it seems most 60hz monitors are shat in picture quality and great in response time and lag input or vica versa..

  • This setting will make the colours look really good- Picture mode:photo, brightness: 100, contrast:50, color vibrance: 13 and all other settings as they are. This will make the visuals better.

    • probably on of them. THE BEST is a bold statements. It is one of the best and as far as input lag and grey to grey yeah it probably is the best, I could not imagine to much better than 1ms gtg and input lag

  • Adeel SoomroIf i use the 27″ on the 24″ scaling option, does this reduce the resolution? Or does it stay 1920 x 1080? I had someone say it can’t stay the same, but it says that the scaling is the same, what is the truth of the matter?

  • Adeel Soomro if i use the 27″ on the 24″ scaling option, does this reduce the resolution? Or does it stay 1920 x 1080? I had someone say it can’t stay the same, but it says that the scaling is the same, what is the truth of the matter?

    • 27″ and 24″ will both be 1920 x 1080. (actually the 24″ will have more pixels per square inch so in a way the 24 inch will be “high definition”.

      if you find the last sentence confusing just dont worry about and remeber : 27″ and 24″ will both be 1920 x 1080

      • Problem with 24 inch version is that it has a lower nits of 250 which sucks. The 27 has 300 nits making it a brighter display

  • Hi everyone! Is it possible to find better 27” solution for PS4 gaming? Is this monitor really the best of the best? I am currently using RL2455HL and it is ok, but I would like to have better picture quality. I am not a pro, however I don’t want to have any NOTICEABLE lags or anything like that. Maybe some IPS monitors would give the highest picture quality?

    • Well i gave a shot on this 27″ and i’m loving it, it doesn’t have some features and it’s really bad get to the menu to vol+-, but a got to say, my game is another game…now i can play street fighter and a lot of precision games without worries, i ask myself how did i even played on tv all this time.

  • Very nice and helpful information has been given in this
    article as I want to upgrade my older gaming monitor with newer one and I search
    many blog for information on Gaming monitor and this blog is just amazing. Thanks for sharing.Cheers!!!

  • Do you know if BenQ are going to release a 32 inch version of this monitor? I’ve tried console gaming on 27 inch monitors and they’re just too small for me.

  • Hi. I play USF4 and I recently switched from a 32inch monitor to a 20inch monitor and noticed I could play substantially better, as though I could process everything going on in the game way easier. Now I’m trying to decide on whether to get this monitor or the 24inch variant of it. I’m worried 27inch might be too large for this game. If you know and have experienced what I’m talking about, what are your thoughts?

  • between this BenQ RL2755HM and BenQ RL2460HT, which one has better picture quality?

    If the 24” is smaller it should look slightly better for pixel density right?

    Then why do you say the 27” picture quality is much better than the 2455HM? Is it the same for the 2460ht?

  • Hey, I bought this monitor because of your awesome review thinking it would be good. But I get INSANE ghosting on white backgrounds. For example when I occasionally play WarThunder dogfight planes that are in front of clouds, I get the worst ghosting I have ever seen. I have the exact settings you guys said. What do I do?!?!

  • Great review which convinced me to buy this monitor! It is brilliant, but I’ve got one question for u guys.
    Does contrast settings from 50 to 60 can couse any inconvinience with motion blur or the others important parametres for gaming? Higher contrast makes games more cinematic. What do you think Guys? I use it for ps4 only. I use fps mode and high AMA.

  • I am debating between the RL2455HM and RL2755HM. Which one shall one go for? I am mainly looking to play PS4 games…

    • From what I am gathering the RL2455 is a great choice for consoles and the RL2755hm is better choice for pc. A lot of gamers seem to prefer the 24 inch screen. Just an opinion. I have been searching for the same answer. Good Luck.

  • Guys, i’m having trouble with the colors on PC(using both HDMI or DVI), sometimes black appear to be brown. It’s because Windows 10?
    Tried different settings and nothing changes, and the ICC profile make it worse.
    On PS4 the colors looks good. My graphic card is Nvidia GTX 550TI.
    Anyone knows how to fix it?

  • nice features.Whether you’re a serious PC gamer or a casual after-hours warrior, your
    hardware can mean the difference between victory and defeat.

  • Hi have this monitor
    I am getting red lines when i connect it with nvidia 1050ti anf they disappear on igpu.
    I am using hdmi to connect

  • Can anyone tell me why I can’t edit the ‘HDMI RGB PC Range’ setting? I have everything else set correctly, but for some reason I can’t edit this setting.

  • I need your help in choosing between this monitor and the Dell SE2717H that will be used primarily for my Nintendo Switch.

    Thank you.
