Inspired by horrendous 2 months of troubleshooting why my browser and everything changes colors when subject to anything such as a video on a Twitter or Facebook timeline or anything that uses the same codec(?), DDU reinstalls, cable switching, reformats, I would love to have that as a tickbox to disable that for myself and whoever else stumbles upon such or worse effects of MPO on RTX 3000 graphics cards.

Do you know if you have to re-disable MPO if you DDU clean the gpu driver?
Using this https://nvidia.custhelp.com/app/answers/detail/a_id/5157/
Or does it persist trough multiple gpu driver installations?

MPO is currently enabled in my registry right?I don't see ""OverlayTestMode"=dword:00000005" in my registry.

Absence of that key = "enabled" I'd assume

Probably not, because it's in the Microsoft\Windows\Dwm key, which is a key owned by Microsoft's Desktop Window Manager, not by the graphics driver

Yea you're right I disabled it and the key appeared and I enabled it again and it dissapeared.
