Same problem...

[Warez]

Maybe it's not the right place to ask, but in HDR why the subtitles looks ugly(er), the edges not smooth at all. When i change to SDR, the subtitle is anti-aliased, and looks nice.
I am using madVR + internal subtitle renderer (but all other renderer do the same), and for the subtitle using desktop resolution.

depnds on the subtitles pgs for example are images and on UHD bd they are still 1080p.

Guys can someone point me to any info on whether there's a nice solution for handling Windows own HDR on/off toggle. I have been using madVR on my C1 for some time now, in Windows 11, with Windows own HDR toggle off and madVR correctly switches to HDR mode and back when needed.

But now that I'm using a lot of new games that support HDR, but they usually cannot make the switch to HDR themselves, I'm considering leaving HDR always on in windows itself.

What I don't know however is if madVR has a way to in this case either switch back to non HDR for SDR content, or do some sort of conversion of color spaces etc and display SDR correctly within that HDR window? I'm trying to make the HTPC wife proof, so don't want to have to press any keyswitches etc to switch in / out of the correct modes for movies/games etc.

I updated Nvidia drivers to latest game ready driver and lost hdr in madvr + mpc-hc. Does anyone know what driver version is the latest that works?

Using the latest Nvidia 531.18 driver with no problems on various players with and without madVR including MPC. Prior to this driver (many builds), after playing various videos, randomly SDR would stick and not switch to HDR when it should have. Sometimes turning display and AVR off/on fixed it, sometimes it required a reboot. Hasn't happened using this new driver after many videos that previously would have occurred by now. Crossing fingers.

No, its normal external SRT

[huhn]

should be the font in that case.
are you sure they are the same between SDR and HDR?

Yes, because when i touch the mouse and go down for open the slider, the picture (colors) switch to SDR colormap, until the slider is there, and then the fonts are smooth.
Maybe it's related to colormap?
Unfortunately i can't show screenshot, because it's on my monitor only. i tried

[huhn]

control print doesn't work?

that sounds like DXVA or other GPU processing

[Sunspark]

You can take a photo using your phone if taking a screenshot doesn't work.

Control print is works, but when i change back SDR, the both screenshot looks the same.
But based on Sunspark's idea, i tried to make photo via my phone, but of course its not very good quality.

Check the top of the "t" letter for example. The top picture is the HDR, the bottom is when switched to SDR. In SDR the fonts are more antialised. By naked eye clearly see the difference, on picture it's harder but noticable.

Thanks Sunpark, link added instead of attachment.

Attachments never get approved here, you need to upload the image to a different site and then provide the link to it.

Hi!

Is deinterlacing supposed to work with D3D11 nowadays? It says "deinterlacing on", but I still see a lot of combing near the edges of things. It's a lot less though compared to deinterlacing being off.

So is it just AMD's HW deinterlacing being garbage? Is it best to use LAV's bobweaver?

[huhn]

for presentation it always worked it doesn't work with d3d11 decode.

AMD deint can work when the stars are aligned correctly at least i got it working on one driver.

else it is utter garbage.

@Warez
check your levels maybe they are over exposed and the fine gradian is cut out.

There is no best, because it's dependent on how it was done in the first place.

What you need to do is load up the file/stream that you're actually going to be watching and try each de-int algorithm one-by-one to see which one works the best appearance-wise. Don't pay attention to the names, only the appearance of the final result, namely the least amount of combing, flicker, etc.

Thanks. I downloaded the latest driver from Nvidia (531.29) and HDR works fine now without any issues. Previously I updated drivers from GeForce Experience. I'm not really sure what the driver version was or what went wrong.

I personally keep Windows HDR always on (on Windows 11).

When playing HDR content with Windows HDR enabled, madVR uses the Windows HDR APIs instead of the NVidia HDR APIs. As far as I know there should be no difference between the two on Windows 11. On Windows 10 however, last time I checked, the Windows HDR APIs did not properly pass through HDR metadata (e.g. maxCLL), resulting in the TV selecting a suboptimal tone mapping curve.

When playing SDR content with Windows HDR enabled, madVR will output SDR, which is then automatically converted to HDR by Windows. I have verified that Windows does this SDR-to-HDR conversion correctly - i.e. it accurately maps the SDR gamut within the HDR "container". However, it's worth noting that Windows assumes a SDR gamma of 2.2 when doing that conversion, which is arguably not great - a BT.1886 (2.4) gamma would be more appropriate. Also, the way your TV displays the SDR gamut when operating in HDR mode might be different from the way your TV displays "native" SDR. (Ironically, on my LG G1 I prefer this SDR-in-HDR mode, because it doesn't suffer from the infamous black crush issues of the LG SDR mode.) In any case, all these issues can always be worked around by configuring a 3DLUT in madVR, if you are so inclined.

I used to have HDR on in Windows but then found the colours were all washed out for SDR content on my Panasonic OLED, pretty weird that the mapping isn't accurate.. But oh well.. It's seamless transitioning here anyway.
