Custom Resolution Utility (CRU)

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

It sounds like your CRT doesn't have an EDID, or the cable is missing the DDC pins. Windows 11 does not seem to process EDID overrides for displays without an EDID. You might have better luck using an HDMI to VGA adapter, which will provide a default EDID if missing, which you can then override with CRU if needed. Without an EDID, NVIDIA provides a default list of resolutions. You can edit that list by searching the registry for NV_Modes and using this guide: http://download.nvidia.com/Windows/43.45...de_2.1.pdf
