For example, in the VTB-EXT and DisplayID sections, the changes did go through but it changed the recognition of those resolutions to DVI.. despite using HDMI cable.. and ALL resolutions became washed out and pale.. and I lost full range colour for all of them. Showing once again, that my 48hz pale colour problem, is a NVIDIA driver issue, not a hardware issue.. as I now had this same colour for every resolution on the list, even the native ones.

So far the only way I've been able to maintain the full range colour that I desire is to use HDMI 'TV Resolutions' that are recognised as 'native' by the NVIDIA drivers. Everything else messes the colour up.

The frustrating part is that 48hz is the only change within all the resolution options that doesn't work. The tick box for native resolution is greyed out, despite being ok with my monitor (unofficially), where as 24 or 25, or 100hz is able to be ticked. And I even switched to this mode (25hz) without my monitor supporting it and then had the monitor go black and say that it isn't supported. And have to revert back. The tick box is available to tick for all of the others, and NVIDIA Control Panel will recognise these extra modes which is exactly what I've been looking for.. EXCEPT the one mode that I really want.. 48hz is unavailable as a native resolution.

It sounds like the driver might only be applying the color format settings to TV resolutions, not necessarily native resolutions. 48 Hz TV resolutions are new and are probably not supported by the driver yet, and you can't define them as native resolutions that way. The only way to define 48 Hz as a native resolution is to make it the first detailed resolution, but that probably won't solve the color problem because it won't be treated as a TV resolution.

Have you tried this tool? http://blog.metaclassofnil.com/?p=83

If that doesn't help, try adding a video capability data block and leave the selectable RGB/YCC ranges unchecked. NVIDIA's driver sometimes mixes things up if those are checked.
