madVR - high quality video renderer (GPU assisted)

[Klaus1189]

Not now, but try out the new driver first. Be sure to make a screenshot of your custom reolution specs before installing the new driver.

I think you use an ATI card, Klaus

But it would be great if someone who uses this szenario or has the knowledge about madVR internals could answer my one and only question:
"is madVR able to switch automatically between 8 and 12 bpc when neccessary on a custom video mode with a nVidia graphic card?"

huhn and me both "think" that it "should".

When I find the time, I will also upgrade to the latest nVidia driver. Maybe it will work then. I will let you know.

So again my question: is madVR normally able to switch automatically between 8 and 12 bpc when neccessary on a custom video mode with a nVidia graphic card? The word "should" in an answer does not help btw. because it means that the person who answers also doesn't know. I also thought that it "should" do this but it doesn't on my side.

nothing is absulote in computers there are to many variables.

custom resolution and 12 bit are not good friends and it is pretty much not worse the hassle anyway.

I do have this working on my setup, but I'm not sure how I got it working, I just got lucky and I didn't want to touch anything after getting it to work because it might just break later.

But I think it might have to do with the fact that I'm using a 4K e-shift projector which I use at 1080p60hz by default, and then switch to 4k24hz 12bpc when watching videos in madVR. Before, I had been switching from 4k60hz 8bpc, and with this setup I was not able to get NVidia to switch to 12bpc. My workaround might not be useful to those that need to run more than 1080p outside of madVR but I thought it was worth mentioning for anyone that this would work for.

Also, I have found that enabling 12bpc color is worth it and visibly better than 8bpc when using madVR debanding on animated content that has banding. If not using debanding I'm not sure there would be a noticeable difference on most SDR content.

@thewildsun

Check your projector's manual. I think it may not support 12bpc in 4k60 mode. Only 4:4:4 in 8bpc.

Of course. Should have posted initially. Thought it might be a common problem. Note the screenshot is using my monitor but the same thing happens on my C9. Also, the OSD states RGB 8-bit full but I get the same results when using correct output for HDR files.

Please upload on external file hoster like google drive, we can not watch the screenshot for now.

[YukonTrooper]

Thanks. I updated my post with image link.

May I ask the reasons why "Full Screen Exclusive" may not activate successfully? How do we address it as well?

[Klaus1189]

@YukonTrooper: What graphics card and what TV, more likely PC-monitor do you use? 165 Hz!!
@Magik Mark: What happens instead of successfully activating? Black screen, crash, ...

[RealSnoopyDog]

@thewildsun @Klauss1189 @huhn : Thank you So I will install the latest nVidia driver and hope that it works then... You are right thewildsun, for 4k / HDR Blu-Rays, the picture quality is much better with 12 bpc

Which leads to an unsaturated color in the "AMD HDR" mode with Vega iGPU.

It simply goes to full screen window mode in dsplayer. In MPC BE, the app stalls and sometimes blank screen

@YukonTrooper: even though the pixel count of your video gives an aspect ratio of 2.39:1, the aspect ratio is reported to madVR as 1.78:1 by whatever is playing/decoding it (line "movie 3840x1608, 16:9") so madVR stretches it to that aspect ratio as instructed.
This is probably a metadata mistake in the source. If this is a MKV, try to open it with MKVToolNix or some other tool and change/remove the 16:9 aspect ratio tag.
Edit: often this happens because a MKV has both 'aspect ratio' and 'original aspect ratio' tags, the second one indicating what it was before cropping i.e. 16:9 if the source was a Blu-ray with black bars, and the decoder passing the original aspect ratio to madVR instead of the actual one.

Hi, anyone else running a AMD RX 5700* in a ageing PCI express 2.0, assuming the PCIe 4.0 will work in the slot I might be getting my hands on one soon, just wondering if anyone has any issues with MADVR in this area, or whether anyone thinks I might see any problems with 2.0/4.0 compatability and MADVR.

Use Display Driver Uninstaller (DDU) (safe mode) to remove stuff of all drivers already installed like registry entries, .. then install newest driver clean.

Also AMD is providing an uninstaller which restarts pc in safe mode uninstall all stuff then you can install the new driver completely fresh. Link is in the first post here:

the only difference between 8 and 10 bit is the noise floor it is unable to do anything else.

Pretty sure it needs a PCIe 4.0 board. Mine would not post using my old PCIe 2.0 mobo, so I upgraded, but that could have been just my setup.

I've done that ever since. Same problem
