I have deleted the previous 3D Luts, since they were created working on my previous TV, and selected "This TV is already calibrated" with BT2020 and gamma 2.2 . I haven't tried report BT.2020 but I'll do! Actually to me it's not really clear this function... I start having doubts about another setting and the doubts comes from many post here: - madvr is configured with 10 bits or more (the TV support 10 and 12 bits) and fullscreen windowed. When I play something it reports the bits correctly. - I configured NV control panel to 4K, 60hz, RGB 8bit when I'm not watching anything and 4K, 23hz and 12bit during vision (again mainly 4K HDR content). BUT I found more than one post like this: Quote:

For a 4K UHD display (Sony 940E) that switches into HDR mode automatically, what is the proper setting for the "calibration" tab? Should i select already calibrated to rec709 or bt2020? I have HDR being passed through to the display via madVR (Nvidia 1070.) I watch both 1080p bluray and 2160p HDR via madVR.

For your color gamut issue, almost all SDR content is mastered to BT.709 and the TV should ship set up to handle BT.709 sources, unless you deliberately changed the TV color profile to BT.2020 or DCI-P3. If it has an auto setting, I would select that and the display should automatically select the correct color profile.

Gamma 2.20 Those are most common.

Hi.
Are there any screen shots to see how madVR's scaling algorithms compare? Also i'm all new to this so please bare with me. If I wished to watch a 4K HDR movie without HDR, do you simply select 'passthrough HDR to display' and uncheck 'send HDR metadata to the display'? As I've tried this expecting the 4K image to look similar to a 1080p pic and it doesn't. I used the same picture settings for each, yet the 4K looked a little washed out in comparison.

Yes, you need to convert HDR to SDR for it to look correct on a SDR display. madVR does this pretty well but it will never look exactly like the SDR master. Mastering is a creative process that results in different video for SDR and HDR.

The calibration settings only refer to the display's SDR mode. HDR content is passthrough unless you select pixel shaders with SDR output.

Maybe Wull wants to compare HDR and SDR to show a comparison to other people?

Since your display supports HDR you would need to set madVR to convert to SDR using pixel shader math all the time.

That sounds like the definition of HDR on a projector.

THE TV could be in SDR, but it's outputting what the HDR signal should look like (in HDR) as rendered by Madvr. The HDR to SDR shader is advantageous because Madvr currently does a better job tonemapping than many, if not most tvs for HDR content. You are not suppose to compare an HDR file to SDR file, they will never look the same, because they are color-graded differently to different specifications. HDR to SDR does not chop off the HDR and leave you with an SDR image. It's taking an HDR image, and sending it in an SDR signal that the TV can understand in its SDR mode, but the image is still HDR.

I'm sure it will be fixed, but it was/is an issue.

sorry to insist, it should be fixed, the hotfix was released last week. As i posted days ago.
IMO keeping to state: "there is, was, willl bugs" creates just confusion on users. It looks like more a win10 blaming without reasons another story if there is something tested with hotfix installed and the bug persists......
