Just to keep everything complicated I do get the correct composition rate for 24Hz (23.976), 60Hz (59.940), and 120Hz (119.880). I also get even 85.000, 100.000, and 144.000 for my other supported refresh rates.

I am running Windows 10 Pro 1607 build 14393.187. Nvidia Titan X (pascal) with driver 372.70.

Set present 16 frames in advance for windowed mode and uncheck Overlay, Fullscreen Exclusive, and DX11. Go fullscreen, maybe 1440p or higher is required?

Reproduced it. My first driver crash ever after four weeks of GTX 1070 usage, apart from OC.

Hi guys, I own an htpc with a gtx 970.
This card can send HDR Metadata to my jvc x5000 projector?

I've downloaded the masciola's hdr-10 test patterns and reproduced with latest madvr with hdr Metadata passthrough actived.
In invidia panel I use UHD RGB at 12bit out.

But to the projector (I verified with HD fury integral) do not arrive any hdr Metadata.

Maybe my graphic card is not able to pass hdr Metadata??

Thank you

madVR can't send HDR meta data to your device.

Can you explain it better?
Why?
Madvr has an option to pass hdr untouched...
I'm in wrong?

Please describe the situation better.

Thank you

madVR can pass it untouched but you would need to manually configure your projector.

A standard API for passing HDR metadata out of Windows does not exist yet so madshi has not implemented anything in madVR yet.

Can confirm this, with 16 frames in windowed without overlay get a crash on 290x at 1440p on win10, if lower it to 14frames all is fine. My 'default' is overlay with 10 frames

I don't know if this is lav or madvr. When I watch mvc movie. My intel gpu hits 100 percent and I get glitching and worse my wireless hdmi cuts out. I had 100 percent gpu usage with normal movies and I changed to dxva in madvr and that fixed it. Is there Anything else I can do? Cpu usage is 30 percent or less.

By "wireless HDMI" do you mean Miracast/WiDi (connecting to a wireless display in Windows)?
If yes then it's likely you are consuming too many resources and there is not enough left for the software/hardware to process/encode the wireless stream.

From my experiences using Miracast doesn't come for free and there is some overheads with encoding and transmitting the stream. I have not tested MadVR and Miracast though at the same time.

If you mean a specialist HDMI wireless device then you can ignore the above and something else strange is going on.

No its a DVDO Air 3 wireless HDMI system. I know people are using the intel GPU with the Kodi MVC version so my guess is that something with Lav or Madvr is causing MVC to use a lot of GPU.

Is that meaning the HDR metadata of HDMI 2.0a is useless here?

The GPU would have to output the metadata on HDMI 2.0a and madVR doesn't have the ability to tell it to do that. There is no standard API to tell it with. It isn't that the metadata is useless, it is that there is no way to transmit it from madVR to the GPU.

Slightly off-topic but... does this mean that Windows 10 can't output games with HDR? Considering their "Play Anywhere" initiative and the big push for HDR on Xbox One S, I would have expected differently.

There is an issue with Madvr 0.90.24 using Potplayer x64 + D3D11 Exclusive mode + 60 Hz HDTV HDMI TV + Geforce 1080GTX 372.70 + Windows 10 x64 1607 1493.187 and might even before that, I'm not sure what can be the cause.

If I'm using 60 Hz going to full screen there is big black delay till I see anything ( the sound continues while it's black screen ) and then picture is shown. comparing going out of full screen is just instant.
If I'm using 59 Hz going to full screen is quickly as going out and in and is instant . I tried disabling Full Exclusive mode in MadVR and it was fast.

What could be the cause ? Drivers ? Windows ? MadVR Exclusive Mode ?

Exclusive mode + OS + Drivers, there has always been a noticeable delay, based on the OS and drivers, when switching into Exclusive mode. I don't use exclusive, it doesn't make anything better for me and it has that mode switching delay.

Yes, Nvidia has an API, I understand, but madshi doesn't like it and it wouldn't work on AMD or Intel cards anyway. There isn't a normal Windows API for it right now but Microsoft could probably implement something custom for Xbox One S HDR enabled games if they wanted to. Hopefully they will have a standard API by then instead.

Again there is no delay when I'm using 59 Hz, when using 60 Hz there is black screen delay of almost 2 sec. that's the kind of delay I'm talking about. it's hard to explain it but I think delay means you need to wait and don't see anything while instant means it you just click and almost you didn't noticed anything. so this what happens . I can't understand why 60 Hz can't work properly, I think it's something with Nvidia Drivers. I just wanted to know if someone else with HDTV having the same issues with the nvidia drivers.

Windows 10 1607 (ie. Annivesary Update) and its WDDM 2.1 received support for special HDR color formats through DirectX.

If its useful for HDR video playback in the future will have to be determined.

Hello,

I use MPCHC + MADVR for 1080p sources (BR) on a 1080p diffuser. The image decoding is achieved by LAV -> Nvidia Harwdare deocder.
Whatever the settings in madvr, I can clearly see some aliasing on straight lines, for instance 20th Century logo at the beginning of movies. Even with all sharpening features disabled. Image doubling reduce partially the aliasing using the maximum NNEDI neurons (which is not affordable).

Is this due to the hardware Nvidia Cuda decoding? I activated it for HEVC content, should I disable it for x264 content?
