So when you see this title you might think that I forgot, or didn't know to put "Output dynamic range" to full in nvcpl. This is not the case, I even tested with madvrs full range tool. Let me explain the issue, the symptoms and what I have attempted to remedy the situation. Hopefully you will have a fix for me. I'm currently on 382.05 on a fresh win 8. (This has also happened to me on win 7). I use Potplayer with madvr and lavfilters and render with Nvidia Cuvid. It looks just great. Whenever I install 388.31, the colors, only on hdmi, not on my dvi-d or displayport monitors they appear washed out, even if I set 'Full range' and/or use madvrs tool (madLevelsTweaker.exe). I'm not sure if its on the desktop, I don't really care how it looks there, but the colours are really washed out in potplayer. I have tried de- reinstallig (the working 382.05) drivers with ddu. DDU btw doesn't reset all settings, as if I set 'display scaling' to monitor it stays until I manually change it even if I use DDU. Maybe this is just some setting not being reset. I have also not changed anything in pot/lav/madvr over reinstalls, so these settings should not affect this issue (I double checked every time I had this to make sure). Tl;dr: Colours look washed out over hdmi when using some drivers, for example 388.31, and won't look good until os reinstall, despite a full deinstall using DDU and previously working driver. Any ideas? I want to be able to upgrade drivers without fear it will fubar my movie setup.
