Custom Resolution Utility (CRU)

[wrathloki]

I’m trying to remove the 4096x2160 resolutions from the EDID of my LG CX (to get rid of black bars in certain games) and I’m running into a problem. After deleting these resolutions, closing CRU, and restarting the computer or running the restart tool I get no signal on all monitors connected. I have to forcibly shut down the computer, disconnect the HDMI, boot back up, and run the reset tool before reconnecting the HDMI to get the TV displaying again. How can I get this to work? My video card is a 3070ti and current drivers are 471.41.

Edit: Looks like I’m having the same exact problem as JayBee, also with an LG set.
