Custom Resolution Utility (CRU)

[Poseidon]

So my monitor (AORUS FI32Q-X) has the stupid 4k downscaling technology for compatibility with consoles since it's a 1440p monitor, so my computer thinks it's a 4k monitor because of this. I tried using CRU to remove the 4k resolutions from both the TV Resolutions data block and the Display ID 1.3 extension block. Every time I do this and use restart.exe or restart-64.exe all of my displays start glitching, freeze on whatever it is displaying, and then go black and stay black getting a little brighter then go back to black. I was trying to do this because tabbing in and out of full-screen games takes anywhere from 5-10 seconds and it is just infuriating. I hypothesized that this is because the display size is changing between 1440p and 4k because of whatever downscaling module is inside of the monitor, but I do not know exactly. I'd appreciate any help fixing my incredibly long switching between fullscreen games problem, and getting CRU to work to see if this will fix the issue as well. Thanks!
