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.

Thanks for your reply, I'll give those ideas a go.

Yes, that's exactly what's happening, but it's only applying them when it's a combination of TV Resolutions AND Native resolutions.. Native = Limited, TV = Limited, but TV + Native = Full RGB.

And also.. I haven't read of this happening to anyone else, which makes it hard to know what the problem could be or how to fix it. There does usually seem to be some complications with NVIDIA when it comes to HDMI and full colour though, over all of these years.

Yeah I did try the Full RGB toggler. It actually crashes when I apply it, which I've read around the internet sometimes people say that happens (and other people have no problems). But in checking the registry entries, I did find that it was applying the changes, despite the crash. So I figured I should just ignore the crash and use it anyway. All it's doing is changing some 0's to 1's, and then back to 0's again. Unfortunately I had no luck in terms of it having any impact or difference (so far).

I've even been shopping around for a new monitor in the last 24 hours if that could help simplify things.. I figured maybe a DVI or Display Port connection could help simplify in terms of NVIDIA applying full colour to all of my resolutions. I figured that it's possible a DVI connection could simply apply full colour, because as far as I know it removes the "Full" and "Limited" options from the menu. This monitor was using HDMI the last 4 years, so I bought a HDMI to DVI converter, but silly me.. I didn't realise that it would still be a HDMI connection. Apparently this monitor has no DVI options, hence my problems. I've been using this HDMI monitor or watching videos from different regions for many years, but have only started to properly understand all of the options or possibilities very recently..

Also.. it seems that the NVIDIA - HDMI - Full vs Limited thing has been an issue for NVIDIA for many years. I've read of people having many problems, which introduced the need for that toggle tool. But I don't know if I've read anyone that has this issue that I seem to have.. in terms of it only applying the full colour to native + TV resolutions. Very frustrating because.. what's the point of using any custom resolutions if it makes the colours go pale and washed out? To have to change colour profiles everytime I want to watch something in 24p, is not a very reasonable request, even to reduce brightness or add contrast isn't the same as full RGB colour.

I am very motivated to try and fix this.. but nearly all of the monitors I have looked at are HDMI.. and I expect to be a NVIDIA user for the foreseeable future.. so it's a bit of a headache.

There seems to be two types of monitors I am looking at.. those that have 50-60hz native resolutions, like the one I am using now. And I am able to underclock to 48hz for 24p video. Or a second set of monitors that are 60-75hz.. where maybe I could use 72hz custom resoution for 24p. But the colours would be wrong because 72hz isn't a native HDMI TV Resolution. And also, the PAL stuff is sacrificed. 25fps stuff should be ok, but the 50p stuff wouldn't be in sync at 75hz. I've just watched two 50p HD videos on YT in the last hour, when researching these monitor solutions in the first place. It's not a major issue.. but I would really like a solution that allows me to watch all video content at the correct synced refresh rate.. to give flexibility for any video editing situations that might present themselves.

Maybe I could find a monitor that has DVI output, just use regular PC custom resolutions, and hope that my drivers apply full colour to them, but finding monitors that have VESA mounts, the right size, resolution, the right type of panel and everything else + DVI has been harder than I expected.

In terms of the syncing frames in video, I'm even noticing a difference in terms of the playback graphs and also the actual playback to the naked eye when using 48hz vs 47.952hz in terms of properly syncing the frames. So I don't actually want to run 48hz for Blu Ray video, I want to run 47.952. And 59.994 for NTSC. PAL stuff is the only one that uses a round number and syncs perfectly at 25/50hz. The easiest solution would be to run my monitor the way it is now, but just have the full colour for 48 (or 47.952hz), rather than monitors that run at 75hz, or 120hz or 244hz.. but whether that's possible or not, I'm not sure..

Thanks again for your reply (and for your CRU tool), I will try your ideas and keep experimenting.
