I get this error when adding a custom super resolution:
"The custom resolution settings are not compatible with this display. Reconfigure your settings and try again."
This isn't related to gaming, I'm just trying to set the resolution permanently to 2260 x 1270 (the native resolution is 1080p) because I want the same pixel density as my 1440p monitors. This worked with an RTX 3080 using the same monitors.

I tried all of the Presentation / Timing Standard options.
