You have Smooth Motion enabled I assume. Yes at 60Hz frame blending gives a noticeable reduction of clarity in motion. At 120Hz it's much less of an issue. Ideally match the refresh at 60Hz.

Yeah but it's on my desktop, I don't really watch movies on it and don't plan on getting a 4K display for it.

Yes, I understood that, and I confirm that it works if you do that. I must have been using NGU chroma when I tested that option a long time ago which is why I had wrongly concluded that it didn't work in that scenario, but now I'm using ReconSoft and it works.

I do not have smooth motion enabled.

I think it has to do with the frame hold times of the TV.

Sounds like it.

Still using w10 1803 and madvr works fine,though I use It on desktop. On laptop where performance suffers, MPC vidéo decoder offers also good quality without heating the GPU too much.

[mrmarioman]

is there a way for madvr to change to 10-12 bit automatically when it detects a hdr movie? kinda annoying having to change it every time in nvidia control panel.

[ang3l]

recently bought a panasonic hz1000, connected with an amd rx480, windows 10 1909, latest amd driver 20.11.2

I have a problem with the sdr black levels, when windows recognizes the display as compatible with hdr it darkens the black level, in the black clipping test practically nothing flashes, but also has effect also on the desktop

but if in the tv settings I turn off an hdr option that make to appear the tv as not compatible for hdr in windows the black levels then are perfect

so what it can be?, what does windows when it recognizes an hdr tv even if the use hdr option is off?

@mrmarioman - madVR has no control over the driver settings. Depending on the display, 8-bit can actually be better. You didn't give us any info on your setup. Assuming you are running the desktop at 60Hz 8-bit, the video driver will switch to a higher bit rate automatically when going to a lower refresh rate, if you set it manually once.

[VBB]

@ang3l - since you are using madVR, you should not be switching Windows into HDR mode manually. Windows shouldn't do anything differently. Sounds like the AMD driver is doing something.

Hopefully one of my last questions:

Since I am using the HDR to SDR tone mapping with MadVR - my PJ is in SDR mode with BT.709 color settings.

Should I set the display to being calibrated for BT.709 in MadVR settings? Or is this redundant?

[VBB]

Yes, you should. Match gamma as well. The more madVR knows about your setup, the better.

yes, windows is in sdr mode, "play hdr game and apps" turned off and also the tv recognize the input signal as sdr

I forgot to report that the skin tones are way too reddish, so it may also be related to wide color gamut in some way, but in the amd radeon settings panel there is nothing about it, I tried to switch between rgb full range, limited, YcbCr 4:4:4 etc, but there is no effect, always darkened blacklevels and oversaturated colors

on the tv I tried to change all the settings, but the only one that works is that "setup hdmi hdr", which turn off the hdr functionality for the selected hdmi port

p.s.

another thing, if I leave that option on the tv on, so the hdmi on the tv is able to receive hdr metadata, but I connect the pc to the tv through my avr that is limited to 1080p with no uhd funciontality the black levels are correct

just to dimostrate that is not that option on the tv that turn wcg on for the incoming signal

I also tried to output the desktop at 1920x1080 connecting the pc directly to the tv, but nothing, windows recognize an hdr capable display and black levels/colors are wrongs

[VBB]

Sounds like your gamut and black levels are wrong. I don't know about Panasonic's, but if there's an AUTO setting for gamut, use that. For black levels, it depends on what you set for the video card, but the display needs to match that. If blacks are crushed, then there's a mismatch.

I have a Sony X900F TV connected to my PC.
Madvr allows you to automatically change the resolution and refresh rate of the display depending on the movie source you play, but not the bit depth. Which is a bit of a nuisance having to manually change from 8 bit to 10 depending on the movie. I was hoping there was a way.

My PJ is set on 'gamma 7' - which I believe is a SONY thing - not to one of the numbers like 2.2 or 2.4.

[VBB]

@mrmarioman - if your display doesn't have any issues with 10/12-bit, why not just keep it at that for everything? I don't understand why you would want to switch depending on the movie.

[VBB]

@LordX2 - According to Sony "Gamma 7: Produces a sharper picture by emphasizing darker parts". Seems to be the darkest out of the available special modes, but unclear if it targets 2.2 or 2.4. Since you tonemap with madVR, it would be good if you entered the correct value there.

Well, my TV at 10 bit only allows for 4:2:2. And I use it for gaming etc. So full RGB is needed sometimes. I guess with HDMI 2.1 TV's this will be a non-issue.

[VBB]

Yeah, there's no automatic way to switch between color spaces, but again, you could simply leave the driver at RGB all the time and then auto-switch between 8 and 12-bit automatically depending on refresh rate. RGB should be superior to YCbCr 4:2:2 anyway.

Do you have Report BT2020 to Display set in MadVR? Try turning it off. I believe that this option will send HDR metadata even if MadVR is tone mapping to SDR. A dark overly red picture could be a sign that your TV is switching to its HDR picture mode.
