Hello to flickering chainsaw edges and morie patterns all over the image.
YMMV I guess.. I had a good laugh from this though.

Not entirely true, madshi developed this using various ground truths, in many cases this would produce a natural and accurate image. In saying that I doubt I'll use it any time soon.

greetings to all ..
is there a way to mask the image in the top of the screen side with madVR?

How should I configure madvr/lav in order to perform HDR-->SDR conversion and leaving BT.2020 untouched?

I have a JVC projector and a popular method of watching UHD is to let Panasonic UB700/900 do HDR-->SDR conversion with BT.2020 passthrough with the help of the HD fury/integral. I am basically interested in doing the same thing with Madvr since I now have HDR content on my HTPC. I am thinking this should be possible?

Just set your display device in madVR to be native BT.2020 ("is already calibrated to bt.2020" on the device page), then it should leave it alone.

Ok sounds good
When MadVR is set to "is already calibrated to bt.2020" and it receives rec709, I assume that it leaves it untouched and doesn't try to expand the gamut? I am looking for a "set it and forget it"-setting and only adjust the color gamut in the projector depending on content.

Back to the drawing table madshi
I haven't been following up NGU very closely recently, but last I remember everyone was raving about it. Samples looked great with it. Did people's opinions on it change?

No, it is just that Patrik didn't like it. You can never please everyone.

4k 60mhz 4.4.4 exceeds 18Gbps bandwidths? Are you sure?
I use it but change automatically to 23/24 mhz when the movie is 23.976 fps...

Always with uhd deep color enabled. Using in 60 mhz or 23/24 mhz noticed that it looks bad or choppy.

For my NGU does a good job. Much faster than neddi.

For >=10 bit and if you add the overhead: yes.

Should I see wrong when it exceeds the bandwidth?

It cannot switch to that mode at all. Either there will be a fall-back to a different mode or there will be an error message.

You wouldn't see anything, your GPU wouldn't allow to send anything above 18gbps, so even if you try to force it, you wouldn't get a signal...

btw it's hz not mhz....

I use it 4k 60 mhz 10 bit 4.4.4 without any problem.

You don't, at least not via HDMI.

use rgb or ycbcr444 for hdmi 2.0b (Gtx 1080 and lg ef9500 uhd deep color) and madvr exclusive mode 10bit 4k 60mhz.
Do not tell me just "no", pls explain why you say "no"

Because its physically impossible. Its beyond the bandwidth offered of HDMI 2.0. Nothing can change the physical properties of the HDMI protocol.

Just because madVR is in 10-bit mode doesn't necessarily mean your GPU outputs 10-bit to the TV.

The best you can do is 60Hz 4K 4:4:4 8-bit, or if you really want 10-bit for some reason its down to 4:2:2.
Its a shame they didn't increase the HDMI bandwidth slightly more to allow this, but alas they didn't.

HDMI 2.1 is supposed to be officialy announced at CES in January. All so far known about it is that it'll add dynamic HDR support - if it'll also increase the bandwidth is unknown (to me, anyway).

every information I've read so far has been suggesting there is not a bandwidth change and 2.1 will simply be a firmware update...

Clarisimo!
So, when madvr says 10 bit in exclusive mode, what does it mean? I guess, madvr converts 8 bit into 10bit?

this means that Madvr can never match or exceed the quality of the native TV player?

pd. Happy New Year to everyone!
