Custom resolution on GSync 360hz monitors

Post by iceboy » 04 Oct 2021, 14:28

I have tested on both ASUS PG259QN and Dell AW2521H, any resolution/refresh rate combination that is not in the preset results in black screen. Tried 456.71 and 457.30 drivers, NVCP and CRU, DP and HDMI, Gsync off and on.

Is this a known limitation of these monitors? It seems Chief managed to get custom resolution to work. Is there any way to make it work?

You are able to use custom refresh rates on gsync module monitors, but there is a caveat that comes along with this. You cannot modify active pixels for different resolutions. This aside, as long as your pixel clock remains within 10 mhz of the monitor's max then you're pretty much free to do whatever you want in terms of refresh rate, gsync module monitors are exceptional when it comes to being flexible with it's refresh rate. The easiest way of going about manipulating the refresh rate, is through the modulation of the vertical total. If you want a higher refresh, lower the vertical (vice versa if you want a lower refresh).
