madVR - high quality video renderer (GPU assisted)

[huhn]

depending on how he cabled it it makes sense.
bad implemented arc solution are not rare.

I don´t know why but I was having several issues with this route:

VGA HDMI 1-> LG OLED C1 -> AVR (VIA ARC)

My solution:

VGA HDMI 1 -> LG OLED C1 (AUDIO DISABLED)
VGA HDMI 2 -> AVR (EXTENDED AND AUDIO DEFAULT)

I know there´s a route 3 (VGA -> AVR -> TV) but my AVR is not dolby vision compatible.

Hi, I dont think that is right, I have mine setup as follows.

ARC port on TV is connected to ARC port on receiver, then receiver input is connected to pc.

Does it have expiration date?

[huhn]

without further notice they all have an exploration date until a different if not worse system will replace that.

Are you having problems ?

it's different madVR uses mostly shader and these don't benefit massively from vulkan which uses a completely different shader language so everything has to be rewritten for most likely small gains at best.

there are reasons to do that for feature like dx12 or at least 11 but this is a lot of work.

cant figure out where to autoforce bt2020 without having to use a hotkey yet still, im talking bout forcing, also shame bout vulkan not working like that with shaders ....was just throwing out some ideas how to get more gains for rendering without quality loss, btw whys there no discord server yet for this place....im sure that would be pretty welcome , dont ya guys think? the forums are abit....archaic lol

[huhn]

bt 2020 can be forced with nvidia cards and you can use a profile to do that automatically like with HDR force BT 20ß20 else use bt 709.
you fidn the option under calibration.

what does a discord give what a forum can't.

don't get the wrong idea this piece of software is not in the hight of it's development.

[doffen]

I think what sexus want to do is to load bt.709 files as bt.2020 files. This will of course make the blues bluer and the reds redder, but if that’s what he wants then why not?
I’m not sure how to do that with profiles. What I do is tick or untick the “send bt.2020” checkbox based on the files colourspace (not just if it’s hdr).

Newb question:

I am on windows 10 and using madVR with MPC-BE. Is there a way to get madVR to trigger my JVC projector to switch to HDR mode when playing back a 4K HDR file? Is there something I need to name the file or anything else in windows that needs to be set? I'm using an intel NUC as my computer.

Sorry if this question has been asked a million times.

Open madVR settings, edit your active device and set "passthrough HDR to display" + "send HDR metadata to the display"

Thanks for the bit of info! Unfortunately that didn't work for me. Somehow the data is not being passed through to the JVC Projector to tell it to switch. The JVC Projector (NX7) is set to Auto mode but doesn't switch to HDR when using mpc-be, lav and madVR even though it works fine switching when I play Netflix 4K HDR using my Netflix App on the Samsung player. Is there something about windows 10 that is causing the issue perhaps?

[huhn]

your intel GPU most likely.

madVR does not support auto HDR for Intel GPUs.
madVR is long dead.
Use MPC Video Renderer or Kodi for this.

[scollaco]

Thanks for the feedback. The Intel GPU is most likely the culprit then. Will try MPC Renderer to see if it makes a difference.

EDIT - Tried MPC Video Renderer and the HDR flag gets properly sent to the Projector and it switches. So the issue is likely as said Intel GPU and madVR issue. Since the Intel GPU with MPC Video Renderer passes it fine.

exactly this! would appreciate if this feature could be implemented without needing to press a force bt2020 hotkey

[huhn]

if you want to ruin your content by removing 50% or more information in it you just select bt709 and select report bt 2020.

you could also just run a shader that does this...
or 3D LUT or what ever.
