First of all you cannot change overdrive, so you are using OD80 in the entire refresh rate if you are strobing.chirality wrote: ↑29 Sep 2020, 00:49So if I have the Asus VG259QM 280Hz monitor and want to use ELMB-Sync, what would be the best setting/parameters for:
1) 200-280 fps range
2) 100-199 fps range
3) 60-99 fps range
Do some/all of those ranges benefit from using VRR ELMB vs a fixed capped framerate ELMB? I've only just gotten this monitor today so I apologize for being new to this technology and appreciate any guidance provided.
If you use Adaptive Sync (VRR) with ELMB-Sync, at least on the VG259QM, there is absolutely no crosstalk, like literally top to bottom not a single double image, however every single ufo is smeared, kind of like standard ghosting but slightly better.
Asus definitely fucked up the timings with ELMB-Sync + VRR.
What I recommend on this monitor is standard ELMB-SYNC without VRR, this provides a very clear image at both 240 and 280hz with a very low amount of crosstalk, the backlight is perfectly timed even at the highest refresh rate (https://www.youtube.com/watch?v=H1uvrRqvJHs I took a 480fps video to show it)
This monitor can strobe at 120, 144, 240, 280 (and I'm not sure about it but I think 60/85hz aswell) but it is pointless to strobe at 120/144 because there is a noticeable increase in overshoot due to the overdrive being stuck at OD80, which is and overdrive that I'd never use if my refresh rate is lower than 240hz.
If you want to strobe I highly recommend switching Adaptive Sync OFF, uncapping the game engine and limiting the fps with RTSS (I find the exact refresh rate for the monitor, for example 279.857 and I type this refresh rate into RTSS that provides precise frametimes with 1 microsecond precision, vsync seems redundant from my testings).
You can reach very high brightness with strobing on the VG259QM, much higher than other 240hz strobe alternatives and you can easily tweak dark levels with Shadow Boost if you want to keep a low brightness due to strobing fatigue while improving dark scenes, at the same time shadow boost hides minor color inversion artifacts since OD80 is slightly aggressive even at 240hz.
If you have more questions feel free to visit the VG259QM thread on [Board index<The Main Lobby<General — Displays, Graphics & More], we discuss a lot of topics about this monitor + 240hz 10bit tweak, hidden overdrive, ...
Tell me if you want to see a crosstalk test at 240 or 280hz I can make one and upload it on youtube.
