Hi all, I recently purchased a 2k (2560x1440) 144 Hz Gsycn compatible monitor (Lenovo Legion Y27q-20) which is connected to my GTX 1080 via DP. I have been desperately trying to get 4K DSR to work at 144 Hz in the past few days to no avail. Without DSR or custom resolutions, all my games and Windows see a set of phantom 2560x1600 and 4k resolutions at 50, 59 and 60 Hz. When I enable DSR in Nvidia's control panel, again only those resolutions are seen and any other resolution that I add is only seen at 60 Hz and below. If I disable DSR but add a custom resolution of 4k at any refresh rate (including 144 Hz) using the control panel, then Windows can see that resolution and Hz, but none of the multiple games I tried do and the games again only see the above phantom resolution and refresh rates. I have tried getting rid of those phantom resolutions using CRU, but I cannot see them anywhere to remove them. I believe the phantom resolutions come from here: Does anyone have any idea how I can remove or disable those resolutions, or how I can get 4k 144 Hz DSR working in some other way? Previously I used a standard 1080p monitor that I had overclocked to 80 Hz that was connected to the same GPU via HDMI and 4k DSR worked just fine at 80 Hz. I guess the new monitor being connected via DP could also have something to do with this problem but I need to use DP because of Gsync. P.S. My OS is Windows 10 x64 1909 and I am on Nvidia driver v451.67. Also I have already tried DDUing the driver which made no difference.
