  • So, Asus lied about to values of the gaming monitors input lag? (1ms…5ms)
    Then is it ok to use a 4K TV for gaming if you rated “Excellent” in your database? Because there is not much difference if Asus ROG PG348Q’s input lag is 13ms, that means i can use a 40″ 4k 60Hz TV with 20ms input lag, right? (Sorry for bad english)

    • The values you’re referring to is the response time of the screen (motion blur/ghosting). Manufacturers do not list their input lag values on their products as of now. Personally speaking, I’ve been fine with displays 20ms and lower for serious gaming. There IS a very small difference between the two, but you will have to be a professional/lag-sensitive gamer to notice it.

  • Hi, this website is great, you helped me pick my last monitor!

    Any chance you can get the Asus PG258Q in for test?


  • Can you share all of the settings that you used to get that latency on the Asus vx248h, up to trace free setting, hdmi port that was used, ddc/ci being enabled or disabled, and the “splendid” mode that it was set to? Mine feels very laggy and I’ve tried every combination of settings. It just feels way off no matter what.
