As far as calibration goes...

"Most 4K UHD displays have separate display modes for HDR and SDR. Calibration settings in madVR only apply to the display's default SDR mode. BT.2020 HDR content is passed through unless a special setting in hdr is enabled such as converting HDR to SDR."

Thank you so in simple terms, do I select DCI-P3 or BT2020 in madVR calibration setting for my JVC x9900 projector? thank you

PS: I am using madVR pixel shader option not passthrough.. so I am doing HDR to SDR via pixel shaders

Hi folks,

I've come across a few videos that will eventually (usually within 15-20 minutes of playback from any starting point) drop a frame or more (as reported by madvr and my eyes) followed by a major shift in clock deviation (from 0.000xx to as much as 0.0xxxx & from 1 frame drop every 1.0x hours to a drop every few minutes). All other media plays without this issue. The issue occurs with the default madvr settings as well. Here's the media info from one of the troublesome videos:

This technology is already available, it's only used in the Eizo Reference HDR monitor right now, CG3145. $30,000 msrp, $45,000 street price, (highly in demand)

But this tech vastly surpasses OLED's capabilities, because it will EVENTUALLY allow for Backlight blink motion blur reduction. (ULMB)

OLED can not possibly match the motion clarity once that is implemented.



Hisense and TCL also have a variant of this light modulation layer tech using VA-panel. They will be introducing it under their ULED lines in a short while.

The reason I ask is I know that 4HDR movies are supposed to be BT2020 but madVR defaults them to DCI-P3 and when I select DCI-P3 the colours seem to have a slightly more pop to them as BT2020 is slightly washed out in colour ? So was wondering in madVR is it correct to select this display is calibrated to BT2020 or DCI-P3? Here are some pics of my projector when DCI-P3 is selected . Colours are slightly more saturated and HDR has a bit more pop . Would appreciate your advice . Thank you ..
I believe it's recommended you skip the gamma setting page,

Just use HDR to SDR , and when you calibrate, run the porjector setting at its 2.2 gamma response setting, and also Select 2.2 in Dispcal/HCFR

Didn't have the problem with my old Rx 480, but I used it together with my lg oled.

Now I use my vega 56 with my girlfriends old sony lcd tv and the oled moved into the living room. So the vega or the combination of amd and the sony lcd caused this errror...

Also, are you guys sure HDMI intent has nothing to do with this, because I know that one of my tvs will go into a Different Gamut mode with significantly wider red and green with a different render intent.

So if the driver is triggering something in the TV to switch gamut space, that may be the issue, and not necessarily caused by madvr/amd

If you're Green Conscious and have a big tv viewed from 3-4 meters away, probably not.

But if you're rich, and throw money at problems, NGU FTW. !!

Ok, so, If we had say a 750ti. benches 3747.

It won't be able to push NGU upscaling 1080p to 4K.

But if we had it render out into a 24fps 4K file, It should be able to playback the file straight with no upscaling algorithm required, no ??

I mean, this is probably niche, maybe a novelty, it sounded plausible when I first thunk it..

You would have to then store that file which means - if you don't want to consume terabytes storing it losslessly as clsid noted - you'll have to encode it again with a lossy codec which means loss of quality.

Even though I can afford NGU, to be honest, I still prefer the ReconSoft+JincAR combo, quality-wise. It preserves the original picture far better to my eye. And when source artifacts are a problem, RCA is just the tool for the job, regardless of the upscaler.

It might be different for extreme cases like upscaling 480p to 4K, though. Haven't had anything like that to watch in a while.

Yeah, thanks to you and nevcariel I arrived at that product... what can I say? I think your forecast of three years is wildly optimistic. But I obviously hope you are right.

Either DCI-P3 or BT.2020 could work. If you are seeing a significant difference between the two, one or the other may not be working correctly.

There could be a couple of reasons:

- The projector is misinterpreting DCI-P3 or BT.2020. It may not recognize a DCI-P3 source, so it would more likely be DCI-P3. HDR content is supposed to report BT.2020 to the projector because that is dictated by the HDR specification standard. You own an AMD GPU, so you can't check report BT.2020 to the display to make DCI-P3 appear as BT.2020.

- The AMD video driver is causing over or undersaturation with DCI-P3 or BT.2020.

I would test SDR BT.709 content and see if it looks accurate. The colors should look natural without any oversaturation. To test accuracy, also try setting both madVR and the projector to BT.709 and play some SDR BT.709 content.

And, NGU Sharp vs Jinc produces very different black levels too @ 23.976 (on my rig anyway)...

Test file here for anyone interested in comparing...

What scaler are you saying there is issues with ?
