Sorry english isn't my first language and i can't understand the meaning of the word overblow ^^'
I don't have problem in sdr, only in hdr. Color are normal, there's no red tint or strange dominant, the global iamge is only less vivid, strong, like when i play the same file with the tv internal player.
OK, so your problem is with HDR material, is it all washed out, do you have a HDR TV or are you doing a HDR to SDR conversion in MADVR?

so you are getting washed out colours but your TV is definitely switching to HDR mode, are you sure?

Press contrl+J when playing a movie and post a screen shot of your OSD

Hmm. I know most of the audience on AVS are projector owners, so they may have different requirements to people that own high nits/brightness HDR capable TV sets that prefer to let Madvr handle the tone mapping.

I have been and will continue to follow the AVS thread (lurker), but, I may end up keeping madVRhdrTestFinalColor4.zip

What does the TV information say while playing this file? Does it also report HDR?

It looks like an HDR source, although it has an odd mastering peak (1200 nits) and framerate (24 fps).

I assume you tried other files?

Try setting chroma upscaling to something besides DXVA. This is hardware scaling and could be interfering somehow.

You could check if there is anything unusual in the file by downloading MediaInfo and looking at the file contents (right click -> MediaInfo -> Text View). There is a link to the MediaInfo utility at the end of this post and a sample to show what a proper HDR source should report. It might be missing MaxCLL and MaxFALL if these values are set to 0,0, but that is not uncommon.

There is a calibration section in madVR. This only applies to SDR content, but you can try setting it to BT.2020 in off chance it fixes the colors. The code is probably unrelated, but I don't know what else would be producing the wrong colors. Improper tone mapping due to incorrect or missing metadata would be the most likely cause.

Try some other content. HDR demo material is often mastered with incorrect metadata.

The tv info also show 2160p HDR.
Yes, i ve tried lot of different file, that image was only the last one i ve used.
Chroma upscaling is NGU for all the profiles.
Mediainfo looks good
Last but not the least, yes i've tried different option in calibration, but always without change.
During all my attempt i ve also changed lot of hdmi cable, used a dp->hdmi, but always the same result

madvr's being GPU-heavy is a bit crazy, like gaming but only requires memory

EVR CP usually eats up 50MB max of card's memory while madvr uses 100% and wants more, a lot more, so hungry

with default setting madVR uses about the same if not less than EVR-CP.

actually madVR doesn't really care much about Vram without NGU you are close to 2Gb with to 2-3.7 GB when using UHD.

I did enable the NGU (the famous NGU), no wonder it spends so much vram
