Is there a way to stop NVidia cards always switching to RGB when using an EDID override driver?
No, this is a driver problem, but I copy and paste a known fix for RGB, and I presume 2 is the code for YCbCr (1 for RGB, but please double-check):
Run the driver installation file to the point where the file contents are extracted. Then cancel the rest of the installation.
Go to the folder where the files contents were extracted to.
Search for the file nv_disp.inf and open it.
Search for the section [nv_miscBase_addreg__01]
Under this section add the registry value:
HKR,,SetDefaultFullRGBRangeOnHDMI,%REG_DWORD%,2
Repeat this step for [nv_miscBase_addreg__02] and [nv_miscBase_addreg__03] and so on until all [nv_miscBase_addreg__xx" have the above registry value.
Save this .inf with the changes and run the setup.exe in the directory.
