That sounds possible, but I usually disable all "Color Enhancements" in the HD Graphics settings, with the exception of slight tweaking of skin tone, and hue. Anyway, the graphics look better to me in the Kaby Lake NUC when using D3D11. It remains to be seen if they will look better in the Haswell and Skylake NUCs.

My video card is AMD RX480, media player JRIVER, os WINDOWS 10.
Nobody?

Better buy a calibration device, instead of tinkering with some odd settings

It might be a bandwidth issue. For such high resolutions, a lot of data needs to be copied to/from the GPU memory.

Try D3D11 hardware acceleration in LAV Video decoder.

No chroma upscaling after win10 reinstall

Hello,
I have been using madvr for some time but recently I had to reinstall windows. Now all the settings work fine except for chroma upscaling, it doesn't produce any image changes. Any idea on what it may cause this?

You can't have chroma upscaling not work, it's (in 99% of cases) a necessary step to display compressed video. Probably the differences between algorithms are so subtle that you don't spot them.

Press Ctrl+J to see which algorithm is used. Madvr will by default ignore your choice and use DXVA chroma upscaling if you use DXVA native decoding or if the video is interlaced.

Then what could affect chroma upscaling such that before reinstall I could see a clear difference between algorithms and now not being able to see any difference?

In LAV Video decoder I use Hardware decoder "Nvidia CUVID" and for chroma > NGU Anti-Alias (high)

Don't use CUVID, use D3D11 or DXVA2 copy-back.

Use ctrl-J to see the OSD. There you can see what chroma upscaling method is being used.

edit: also disable the rendering "trade quality for performance" options "use DXVA chroma upscaling when doing native DXVA decoding" and "use DXVA chroma upscaling when doing DXVA deinnterlacing".

With D3D11 used all madvr settings are ignored including image upscaling and that works fine with CUVID and DXVA2 copy-back. I already have all "trade quality for performance" options disabled.

Sorin, chroma options don't tend to change the appearance a lot when it is noticeable however it's mostly on red images, I notice your settings are too high in that screenshot, set to NGU AA med or low to get your rendering time down so you're not dropping frames. Some of the 'trade quality for performance' options can actually be quite useful here with little image quality affect.

Thanks, it's back to normal after I reset to default settings.

Did you make a copy first? Madshi may be interested in knowing what's going on with junk in the profile.

Hi!

Any Windows 10 users here?
When I experimented with it a while ago I had a significant issue with video playback: after I left the media player paused for a while and wanted to resume playback the video froze with madVR (not sure about other renderers, I forgot whether I checked or not...). I had to stop playback and restart. Very inconvenient.

Do such things still happen on Windows 10?

BTW. How does it compare to Windows 8.1 from the aspect of multimedia?

anyone else out there with a 2015 or 2016 LG OLED without a pro calibration, just wondering what you've set your MADVR calibration to, DCI-P3 / power curve 2.20 looks the best to my eyes, with calibration disabled MADVR is overblowing colour, mainly reds for me.

No idea if this is even correct.

Is madVR dead or its development stalled?
Did mpv win the battle?

Madshi is often inactive here for long periods. That is when he is busy performing magic. Just be patient, a shiny new version will appear eventually

Yes, I sometimes have the same problem, but it only happens if you leave the PC long enough so that Windows turns off the display. So one workaround would be to increase that time or disable the function completely.
