LG Input Lag Tests: UltraWide, 4K, IPS Monitors

Continuing from our ASUS monitor update back in January, I managed to get my hands on several LG monitors and updated them into our input lag database. This includes an assortment of standard 1080p TN, 4K, IPS, UltraWide, and other types of monitors, so there should be something for everyone! Keep in mind that some of these models require “Dynamic Action Sync” to be enabled, which is LG’s mode designed to reduce input lag to their fastest response, essentially their version of “Game” mode.

  • 29UM68-P (IPS) :

    I just got this monitor, and it has at least one more frame of input lag compared to 23MP68VQ-P. Tested with DP cable, freesync, 75Hz in cloning mode. It doesn’t give me DAS option, but I tested presets where it always said DAS on in the overlay.
    I can also feel it in games, so it is more like 25ms than 10ms. What might be up with that?

    • What’s the advertised response time on that versus the other one? I went from a BenQ gaming monitor to an Asus IPS, and they are both listed as around the same input lag on this website (10ms), however the response time difference from 1 ms to 5 ms was massively noticeable in a game like Rocket League, so much so my performance suffered a lot.
