I went ahead and bought one of those monitors off ebay. I got it to do 200Hz with no frame skipping relatively easily (I even got it to do 240Hz with no frame skipping but screen went solid white after 3 minutes) (I'll add pictures later proving so)
After a lot of testing a fiddling with the monitor these are the things I found.
1. Higher Refresh rates progressively make the screen more white
a. at 200Hz it's quite bad, contrast gets all kinds of screwed up.
b. some tweaks helped; lowest possible brightness you can deal with, setting monitor polarity to - / -, changing some brightness/contrast settings via Catalyst Control Center (monitor doesn't have an OSD menu)
^even with all of that the issue is still quite pronounced compared to a 144Hz 1080p BenQ XL2420TE in terms of the washed out white.
2. Higher Refresh rates make the monitor go full white (it starts and in about 3s entire screen is pure white)
240Hz effect happened in under 3 minutes
200Hz effect happens very sparingly typically after 1+ hrs
a. Effect goes away upon turning the monitor off and on
180Hz Haven't seen the effect after 3+ hrs
b. Whiteout effect isn't related to temps (tried with a box fan next to the monitor at 220Hz which consistently whites out at around 10 minutes, also tried turning up the ambient temp by 4c didn't cause increase or decrease whiteout time)
3. Games are quite a bit smoother and the reduced input lag is noticeable in fast mouse movements at 200Hz.
*new* 4. Another reason to love this monitor; this monitor is capable of supporting a downscale 2560 x 1440 @160Hz timing.
Kinda curious if anyone can help with fixing the issues I had in 1. or if anyone has any recommendation at preventing the full screen whiteout at 200Hz or even 240Hz.
