directcompute should be supported

I cant play 4k resolution downscaled anyway, but even when I make a 1080p x265 HDR encode from my source which plays smoothly I get the same result.

This is correct, but there is something missing.

There are more specs to look at here:
1.) resolution -> UHD - 3840x2160
2.) color depth -> 12 bit per color
3.) Pixelformat -> RGB (no subsampling) or YCbCr 4:4:4 / 4:2:2 / 4:2:0
4.) matching refresh rate for framerate of video -> missing here

It is supported by HDMI 2.0, but only for low refresh rates.

The bandwidth of HDMI 2.0 is known and so you can calculate it by yourself, it isn't that hard

Hi Guys, I recently upgraded my projector from an x5900 to an x9900 and so far I'm loving it. I have always preferred madVR tone mapping via pixel shades and find that 200 target nits with highlight recovery at (are you mad?) and balanced for the other setting gives me the best results.. However.. I find that the actual picture is lacking in colour it's pale and looks desaturated even with the Option at 35%.

Yesterday I went into the madVR settings and upped the saturation from 0 to 22 and I am absolutely loving what is on my screen. I have full pop as HDR should be and I have never seen HDR this great on a projector with accurate colour, shadow details, highlights blacks etc etc... Thank you to
@madshi
and all the fantastic members on here who always help and support this amazing piece of software.

What I wanted to ask was by having my saturation at 22 is that ok? Will it cause an issue like picture noise etc? I haven't seen any I'll effects but am I the only one who finds that at 0 saturation the HDR looks a little lifeless? Would really appreciate some comments and feedback to help me understand better.. By the way I select 0-255, 10 bit or above, BT2020, powercurve 2.4 within MadVR and RGB 4.4.4 on my HTPC at 10bit for 24hz movies.. Here are some pics with the +22 within madVR.. Thanks for all your help...

I would still guess it has something to do with Direct Compute or the version of it used by your GPU, but madshi would have to say for sure.

Sorry, but it is very humble. There is not only 50i/60i.
Every "flatscreen" (-> LCD/OLED/...) is native progressive.
Only old CRTs were able to display interlaced content natively.
AND the deinterlacers of TVs are not as good as software deinterlacers, just try them in comparison and we continue here.
I tested also 20k TVs (20k is not the resolution )

Is it only me but has anyone else using 92.17 and that last xysubfilter build 3.1.0.752 found that madVRs ability to move subtitles into the black bars stopped? The option is moving subtitles down to the bottom of the movie but not into the black bars when they are there. I'm using LAV 0.73 in case thats important also.

the sony OLEd can do interlanced natively

and what software deinterlancer are you using in realtime which your HTPC?

aren't they interlaced ? so what's the point of this discussion ? better 60i to deinterlaced 60/2 fps UHD rgb 10bit 4:4:4 or deinterlaced 60/2*2 fps UHD rgb 8bit 4:4:4 or 60i deinterlaced 60/2*2 fps UHD YCbCr 4:2:2 ? who knows? could be personal decision ? until hdmi stardad is like that, ppl have to deal with.
always imho

@mrmojo: There is no interlace with UHD. UHD broadcasts are 50/60 progressive. UHD broadcasts ARE TV. That's all my comment was about.

HDMI 2.1 will be nice but people care about 10/12 bit way too much, at least on most displays and using madVR it offers a very minimal quality improvement. If you want 60 Hz use 8 bit RGB, it is great quality and you probably couldn't tell whether or not it was using 10 or 12 bit in a blind test.

ok so know makes sense. I thought they still are interlaced the UHD broadcasting.

so no other choice for hdmi than YCbCr.

That's right - so, sadly, no much benefit from MadVR chroma upsampling with 60fps UHD content.

This is needed IMHO, very humble, so someone knows to what he/she is resonding to. But I agree, images should be used as external links. This hole thread is so freaking hard to read, too many prople interacting. I think I leave.

I never deinterlace a source when creating a file, only while playing a deinterlacer should be placed. It doesn‘t matter which one of LAV you use, you will never get a better deinterlacer in a tv. If you use a madvr, you also prefer the updcaling of it and don‘t let your tv handle it, right?
