Custom Resolution Utility (CRU)

[FrannDzs]

Hello, how are you?

I am writing because I am having problems with CRU now in Windows 11. It no longer locks the resolution as before in Windows 10. I have a GTX 550 ti on a CRT display which does not correctly recognize the supported resolution and frequency. These go higher than they really should. My max screen resolution is 1280x1024 at 60hz, and I used to set this to CRU and higher resolutions disappeared from the list, just as I expected. But now it doesn't work anymore. It shows resolutions out of support and therefore the programs start believing that my resolution is 2500x..... Do you know anything about this? I hope you can help me to solve this problem. I really used this program a lot and would like to continue using it.
If you need more information I can provide you.
Thanks in advance
