Interesting open issue in those new drivers:
Windows 10 Issues - When setting the refresh rate higher than 100Hz, the color format switches from RGB to ycbcr422. [3053990]

I encountered this problem a few weeks ago when I tried to setup a nice little htpc with an Intel iGPU but also already at 48 Hz and 50 Hz !! Back then I thought that the hardware/driver had problems with CRU.

News about Nvidia driver for madVR with passtrough hdr?
Hi.
Can someone tell me which is the best Nvidia driver for madVR with hdr passtrough sending metadata to the display? I tried 442.74: it works fine on hdr but there is stuttering on 23.970 fps. Then I tried all the newer - perfect on 23.970 fps - but there is a bug after hdr playback stops... None works fine at all? What about AMD RX5700? It works better? How are drivers? Thanks in advance.

For pass-through, most of us have no issues with the latest Nvidia drivers. I'm on 457.30 myself.

After I stop hdr playback, the gpu continue sending hdr signal. There is a known remedy?

Yes this is how it works, but the question is what happens when you don't close the player but fire up an SDR video after an HDR10 one???

It doesn't do that here, but I recall it used to with older drivers. Maybe six months ago or so. Playback stopped and the display would be stuck in HDR mode until you click somewhere with the mouse. Never bothered me enough to roll back. But again, I haven't seen this happen in a long time.
Note: I do have my player set to close after each playback, of course. Will test later with player not set to close.

For me, in JRiver, when I hit stop, it shuts down HDR mode. I also have madvr set up to restore my resolution which probably has something to do with it.

So the test case: hdr file is playing, you can hit pause or just let it play, then open an sdr video in the same window.

So given nVidia's extensive track record on fixing such things, we can expect the 3xxx super refresh cards to be out around the same time. LOL

I can confirm your bug now, chros
Set player to do nothing after playback stops -> play HDR file -> play SDR file -> TV will switch modes, but SDR content is extremely dark.

Thanks guys, that's what I meant in my summary before, that this is nuts. Literally the last driver that is good (not perfect ) for madvr is the 398.18. And that is 2 and a half years old!!!
And when the fix comes they start to FAQ up something else And amd drivers are crap, right?

Sorry,but for the price of 3090, you will get a much better payoff by upgrading the panel/display....
Just my 2 cents....
