If you remove HDMI support from the extension block, the video card will send a DVI signal, which is always full RGB, but you said the colors were washed out when you did that, which makes me think the monitor just has washed out colors with full RGB PC resolutions. I don't know why you're having different results with TV resolutions. I can't tell if that's because of the monitor or NVIDIA's driver treating TV resolutions differently, but the washed out colors with PC resolutions is definitely the monitor, which is why it looks double pale with limited. NVIDIA's driver probably treats custom resolutions the same as PC resolutions, which is why those are always washed out for you.

You would need to flash the EDID with the exported .bin file, but many monitors have a read-only EDID, which would require a hardware modification to get around: https://www.blurbusters.com/zero-motion-...dware-mod/

Thanks for your reply, sorry for the delay in mine.. I bought a monitor colour calibration tool and it's still sitting in the box unopened since my last post, have had a lot of stuff to catch up on and trying to get everything ticked off one by one. There was one video in particular that had variable frame rate, tcombined with different interlacing options for different parts of the video, and encoding took 36 hours combined with the editing itself which took even longer, it was a complicated puzzle to solve.. but happy to report that the new monitor settings helped me do a good job with it, in terms of ensuring smooth playback and the end result has turned out really well.

I might come back and revisit this at a later point, it seems involved in terms of the hardware modification of the monitor, which would help with convenience.. but in the last week I've had no problems, everything has been perfect.. and it's only one extra step to use the CRU tool.

I'm also a little worried that it could be a one off issue with this version of the NVIDIA driver (or something else) and it could be the future driver versions act differently. It could be that if I reinstalled Windows but used the same driver.. even that could act differently. I don't really know what is the root cause of my problem, other than.. I feel like the NVIDIA drivers are dodgy when it comes to colour profiles and not intuitive or straight forward. I can't say 100% that this is the case, it could be the monitor.. I'm just happy to have found a workaround, and in the last week haven't had to think about it at all, and it's working 100% the way I wanted it to. I am even able to watch YT videos (or live streams) through my video player and it's using the correct refresh rate for each video.

I might look into the the permanent monitor hardware solution if a window/pocket of time opens up and I'm in the right mood to mess around with it. Or maybe after a Windows reinstall or a graphics driver update. It'd be good to wait I think, in terms of having confirmation of where the problem is coming from, or more experience with different versions of video card drivers. In the meantime, this is working ok. And the great thing about CRU tool is that it's flexible for future changes or tweaks if required.

Thanks again for your help on this matter, and especially for the CRU tool itself, it's sort of a swiss army knife in some ways, in terms of being able to tweak or fix a wide range of issues relating to monitor/refresh rates/resolutions.
