I cant see how that can help, if the audio is send in the video packets, black screen, pretend 2nd screen, whatever, it will always be seen as a 2nd monitor. You can disable it but you lose the sound.

So unsure what you think Microsoft will do since this is a well known issue for many years.

that's the point he want to connect microsoft so the add it properly without a second screen by just sending a black image to the GPU.

you select an HDMI audio device if it isn't an active screen it just creates one without the end user even noticing.

I think it will be more like a nVidia issue to be honest, and there are literally hundreds of threads, saying use Pin 19 trick (nope), buy a splitter etc etc. But hey its worth asking.

i don't think it will happen but if microsoft does this it will work for sure and there is "nothing" nvdiia or what ever can do to break it because they simply don't know. if microsoft tells an GPU render A on display B it will do it if it is an desktop or not.

it's a lot of work and needs a lot of testing.

OK I've installed Feedback Hub, I had an insider account before but I'm not using it anymore and it says it's better to sign in but I don't want to link my PCs to my MS account, does anyone know if it's safe to just sign in inside the Feedback Hub app itself, or will it link my whole Windows with my MS account if I do that?

Here's what I would submit, if anyone has any remarks I'd be happy to consider them
Quote:
Summary: allow a video output that can also output audio to be set up as audio-only, creating a 'ghost display' that does not participate in the desktop *

Detailed explanation:

Use cases:
- AVR supporting a lower video bandwidth/fewer features than display, and user wants to benefit from all the display capabilities
- user wants to power off display when playing music via AVR **
- user wants to use gaming monitor for FreeSync/GSync/high refresh rate/low latency, and use AVR only for high quality audio

Problems of current Windows support that this would solve:
* using a separate video output only for audio causes UX issues, as the non-visible display that the user doesn't need to access is included anyway in the Windows Desktop
** powering off a display connected to an AVR while audio is playing usually causes problems, stopping/crashing audio playback

Implementation details:
- the 'audio-only display' still needs to be configurable by the user wrt resolution and refresh rate (see http://www.oppodigital.co.uk/Underst...O-UDP-205.html , recommends 1080p50/60)

Is there any way of making Blu ray PSG subtitles sharper ?
They look so blurry a lot of the time and was hoping there are better bitmap scaling methods I could use to improve this as it is jarring going from my chosen srt font setup to whatever terrible choice the studio has chosen for their blu ray.

It would be good if you shared your full setup as well.
This is the crash report:

My setup is a LG Gram laptop with i5-7200U CPU, using MPC-HC connected via HDMI to an ONKYO Receiver

Hello again, I'm wondering if there are any setting to automatically disable upscaling when playing 2160p(4k) content?

When I play normal 1080p content I want all my upscaling ON but when I'm playing 2160p(4k) + HDR It lags so I then want to disable it since its not really necessary anyway at that resolution.

4K HDR breaks madVR on my win7 HTPC

Hi
I have serious problems with 4K HDR pass through on my WIN7 64pro HTPC sourcing a 4K LG OLED; on my Win 10 HTPC sourcing my 4K projector HDR pass though works fine...

I have had MadVR running for half a year upscaling 720P and 1080P to my 4K LG OLED, with no problems. I recently started to play Blu-ray UHD as well, after buying a UHD friendly drive.
They play fine on both HTPCs, but when I pause or skip (30 sec, 1 min etc), the win7 HTPC breaks down: the movie turns 95 % white. The black cinemascope bars remain black. It continues to play the movie with sound and all. It does not happen every time I skip or pause in all movies; some more than others. However, I can make them all "break" by skipping long enough. When I STOP playback of the movie, 50-70 % of the time, Windows changes from 3840 x 2160 to 600 x 600 and displays a "madVR has stopped working" box.

I have the exactly same settings in madVR on the two HTPCs, except I have full screen exclusive mode checked on the Win7 HTPC and not on the Win 10. That is the only difference.
They have the exact same settings in Nvidia control panel: 23hz: RGB, 12 bit, full; 50 hz: RGB, 8 bit, full. Desktop is set to 23 hz to avoid the Nvidia 12 bit reset bug.
HOWEVER; the Nvidia driver is not the same. My win7 has a GTX 1050 card and uses 385.28, but my win10 HTPC has a RTX 2060 card and needs min. 411.63 (I use 417.71 currently, will try 430.53 soon iot get correct HDR meta data pass through)

WHAT I HAVE TRIED SO FAR:
1) Tested the Win10 HTPC on the OLED TV - It works there as well...
2) Changed the win7 HTPC settings to 8 bit in NCP as well as madVR, i.e. unchecked exclussive full screen mode, changed display settings to 8 bit not 10 or higher
3) Keeping NCP set to 12 bit and unchecking full screen exclusive mode
4) Keeping NCP set to 12 bit, unchecking full screen exclusive mode and checked the windowed mode just above
5) Changed madVR from pass through to tonemap using pixelshading. Aside form the GTX 1050 not being fast enough for that, it actually also crashed when stop or skip. Except not with the whiteout, just with the resize to 800 x 600 and madVR "stopped working" message. I will eventually try this on my win10 / RTX2060 HTPC and projector combo, but I prefer pass through for the OLED.
6) a lot more....

Bonus info: I use Mediaportal 1.22 on both machines, along with madVR. LAV filter is 0.74.1, using DXVA copy back.

I am currentlu considering:
A) updating Nvidia driver on the win7 HTPC to the same driver as on the win10 HTPC (417.71)
B) Doing a clean win10 install on the win7 HTPC...
C) Hanging myself in a garden three

Any one had similar issues or heard of some who had?
Help appriciated!! ;-)

@mambans I understand you're using a 4K display? How exactly have you configured your upscaling? Normally madVR doesn't scale when you're playing source material that matches the display definition.
On the OSD, if the line just after 'movie 3840x...' says 'draw 0,0,3840,...' then it's not doing any scaling.

@jacob Have you checked if the problem can be reproduced with another player like MPC-HC? To know if it's linked to MP or if it's between madVR and the graphics driver.

You probably aren't upscaling 4k but are applying post processing and or high chroma settings. I assume you have not created any profiles and you need to.

Maybe I dont understand...

But why dont you have one go from hdmi nvidia to tv for 4k picture, and one going from dp nvidia to receiver, and then one ARC tv to receiver? I use this setup and it works perfectly and will carry DTS HD master DD+ etc.

Would rather not deal with display quirks doing that and plus I'd need another cable specifically for this, which I'm not prepared to purchase. Will upgrade the amp sometime.

I dont know what display quirks you mean. It is fine. But yes youll need a Fosmon DP to HDMI cable as this is the only one that works correctly $9 on amazon. Or like you said upgrade the amp so u can passthrough 4k60. I did the former as 9 bucks was better than hundreds on a new receiver.

You need profiles set up.
Turn off superRes, try Bicubic 150 as a downscaler, better?

MS just pushed out build 18922 on fast-ring, and banding errors are gone (on my rig), without having to use the workaround.

Also sharpen edges and soften edges enabled at the same time sound counter-intuitive to me, and if using the AR filter integrated with some upscalers you shouldn't need to activate anti-ringing in refinement.
Anyway, rendering times of 24 ms for 24 fps movie shouldn't cause any problems so I'm wondering why it "lags".

Yeah I wasn't about to critizise his entire setup but things are looking overkill and there's something there doing it. Don't always trust the render times..

Here's the link to the feature suggestion for 'audio-only HDMI/DP output' in MS Feedback Hub, if anyone wants to upvote: https://aka.ms/AA5emb3
