madVR - high quality video renderer (GPU assisted)

[tp4tissue]

To Be fair, it looks almost identical, because most panels do 10-bit badly or are not true 10 bit designs.

[Asmodian]

It would look almost identical even on a very good 10 bit display. The difference between well dithered 8 bit and well dithered 10 bit is simply very subtle.

Hi,

i am noob for here.
Have this problem:

Add images:


Same configuration settings TV



PLEX TV Oled c8 - HDR:





TV OLED c8 - Mode HDMI / MODE PC / MODE blueray
HTPC - Vega 11 - MAdvr HDR



The HDR logo is activated on TV. (this is not the problem)

Why is it lost in color?
Has anyone had problems with Vega 11?

THANKS
:-S

Are you sure it isn't your TV? That looks like a very different white point and you do not mention what mode you are using for the PLEX. Try Expert Dark Room for both. Are you using madVR's tone mapping or just passthrough?

Sorry, I have no experience with Vega.

It is also important the FSE (exclusive) or FSW (windowed) you use for Vega. What OS?

PS: No one noticed the image changes a change in Windows10 1903 with HDR passthrought?

That's usually the difference between 709 and 2020. You're using passthrough, or "output video in HDR format" (or 2020 in calibration settings). PLEX is converting to 709.

[Asmodian]

With 2020 displayed as if it was 709 I usually get obviously lower contrast. I don't have a lot of experiance trying to judge photos of displays but the contrast seems similar on both. It looks like a white point and tone mapping difference to me, but I could be wrong.

That's if the PQ transfer function is not applied to the HDR 2020, but in this case it is.

EDiT: But you're right, it seems a different color temperature.

Anybody else tested 1903 and encountered some issues?

[SamuriHL]

Nope. Been running 1903 since it dropped in insider builds a while ago. No issues for me so far.

Sure.
The TV have same settings and same mode (Technicolor) with Plex and HTPC Madvr.

just passthrough.

MMM
I have researched a little, and it seems that the problem continues that way ...

That is to say.
When I deactivate "passthrough", and I select in "calibration" 709, the image (SDR) is very similar in color to the HDR of PLEX (but without the brightness / etc of the HDR, of course.)
When selecting 2020, the image (SDR) becomes more muted, as it happens to me in HDR.

The problem is that I select the options that I select, when HDR is activated in full screen, I always get the SAME result as the 2nd image I have set.

Any solution?
What am I doing wrong...??

What version of AMD drivers and Windows 10?

There is an issue in the c8 with some firmware not detecting the wide color gamut in PC Mode, it is supposedly corrected with firmware update (04.10.06).

After the update, problems started with my 720p sources. Playback is not smooth, but the OSD shows no problems For example, 1080p sources work fine, which is a bit strange for me.
Since it seems that the new madVR build will not be soon and MS focused on more important features like blur, I used the magic button and rolled back to 1803. And everything works fine again
My current setup:
R7 2700, GTX 1660 Ti, 430.64, PotPlayer x64.

There is an assumption that in the 1903 version FSE does not work any more. It seems to work, but like FSW.

[ryrynz]

FSE isn't working for me (1903 + latest Nvidia) but IDC 'cos I don't use it anyway.

[suanm]

Does anyone know why the two optional pulldown lists named '①color tweaks for fire and explosions; ②highlight recovery strength' go grey and they don't work when i click the button 'tone map HDR using pixel shaders'?
I don't know whats going on?What should i do to activate the two optional pulldown lists and make them work normally?

[suanm]

MadVR 0.92.17 is running on windows10 1803 OS and nvidia 385.28 display driver
