Custom Resolution not working

[stv8]

Hello, I am on Big Sur and having some problems getting a custom resolution to work.

I am on a 27" 1440p monitor and looking to either get 1920x1080 HiDPI or 2048x1152 HiDPI working. I made the custom options but nothing happens when I select them.

Fwiw I had 1920x1080 HiDPI working with a different resolution app (ResXtreme) prior to Big Sur, but then the resolution disappeared once I upgraded to Big Sur.

Any help is appreciated thanks!!

Take a look at this reply and see if you are having the same underlying issue. Workaround should be the same I guess.

Thanks for the reply! I finally got my setup to work. I still have unclickable resolutions, but I have the resolutions I want to sue working now. Appreciate the response!
