PG27AQDP 480hz DSC vs 240hz ELMB native

High Hz on OLED produce excellent strobeless motion blur reduction with fast GtG pixel response. It is easier to tell apart 60Hz vs 120Hz vs 240Hz on OLED than LCD, and more visible to mainstream. Includes WOLED and QD-OLED displays.

PG27AQDP 480hz DSC vs 240hz ELMB native

Post by MDLoofee » 27 Sep 2024, 10:48

Hello! I was just wondering what the common consensus is on the PG27AQDP (or similar monitors for that matter) in terms of settings/ELMB setup when playing games where you dont achieve the full 480hz. I primarily play apex and the game has an built in engine cap at 300fps, I can hit this consistently at 2304x1440 which is the res I run. What would give the "best", if there is such a thing, performance/competetive edge in terms of latency and motion clarity. Is it better to match 1/1 with fps and hz at all times or is it better to just leave it at 480hz and uncap my fps?

I appreciate the help!

Highest Hz means lowest latency. This is true regardless of FPS.

ELMB on OLED usually has abnormally high input lag, mind you, due to the very poor method Asus uses to implement BFI. But hopefully the RTINGS review will be up soon where we'll see if this monitor also suffers from BFI lag.

As for DSC, I can't tell a difference with it off vs on. I don't use it myself since it's not needed. I have a 240Hz 1440p display where DSC is only needed in 10-bit mode (which is useful in HDR) which I don't use. But when enable it for testing, I can't actually see any difference in image quality.

Unfortunately ELMB adds 4-5ms of Input Lag ( Source: https://tftcentral.co.uk/reviews/asus-r ... 27aqdp#Lag )

The 24.5 Mode and 1:1 Pixel Mapping also adds 3ms of flat Input Lag.

I know the 24.5 mode and Pixel Mapping is due to Asus poor implementation since if you look and compare both the Asus/LG 32 inch screens you can see that the Asus adds exactly 3ms of input lag compared to the LG adding none despite having the exact same panel.

If you want to play 24.5 I think by creating a custom resolution at 1332p (pixel perfect) you could avoid any input lag but no one has tested that yet afaik. I also don't see why ULMB would add any additional input lag besides every other frame being black, this added input lag seems specifically related to "Signal Processing".
