I wonder if something is getting lost in translation here. I'm saying that I cant get 4:4:4 FULL RGB 60hz 10bit, pretty sure this is unsupported with HDMI 2.0ab/b, this will only be possible with HDMI 2.1

I havent tried dropping to 23/24 hz as I wouldnt operate my desktop at that.

UHD 4:4:4 60Hz 10bit requires HDMI 2.1
With HDMI 2.0 the maximum is 30 Hz for UHD 4:4:4 10bit.

You didn't specify 60p in your post. That's beyond HDMI 2.0a. You need HDMI 2.1 for that. So why are you wondering why you can't get it, if you know that 4K60p 4:4:4 10bits is beyond your HDMI bandwidth?

how are you managing this then, is your desktop set to 420 60hz and you have script or something to drop it into 444 fulll RGB before you play a movie, or do you have to change it manually every time?

One way to work around this is to manually change the refresh rate to 30 or 24 in the Nvidia control panel. Save it and then change the bit rate to 12. Save again. Then change back to your normal setting. When you launch an appropriate video, the nvidia driver should switch to 12 bit.

With nVidia (using 385.28 if Windows 10), as explained many times, you select in the nVidia CP 4K23p (apply), then you select RGB Full 4:4:4 12bits (apply). That's it. Then if the content needs more than 18Gb/s bandwidth in 12bits (say you play 4K60p content), the driver switches automatically to 4K60p RGB Full 8bits 4:4:4, and back to 12bits when the playback is over. There is no need for a script. But it doesn't work the other way around. If you are in 4K60p when you select the bandwidth, then you CAN'T select 12bits, you're limited to 8bits, simply because it's not possible to select more than 8bits in 4K60p 4:4:4.

pretty sure that isnt going to work on an AMD card, will give it a go though, think i'll just get a black screen.

Display output only 8 bit for HDR content

Sorry if my question has already been answered somewhere else, but I haven't found out yet whether my issue is expected behaviour or whether it is an issue at all.

My setup:
Windows 10 Enterprise 1709 64bit
Zoom Player 14
madVR v0.92.10
Nvidia GTX 980 385.69
Marantz SR6011 AV receiver (HDR ready)
Sony XD9305 TV (HDR ready) -> manually set into HDR mode (BT.2020)

When I play HDR content on the PC through the receiver to the TV (for example the Exodus UHD_HDR_24p.mp4 demo trailer), HDR seems to be fine. Colours seem fine to me at least.

However when checking the info screen with CTRL+J, it shows the source as being 10 bit, but output is "D3D11 exclusive 8 bit".

Shouldn't I be seeing "D3D11 exclusive 10 bit" as my whole chain in theory is 10 bit ready? Or is this because of the infamous Nvidia driver or Falls Creator issue?
Any way to get 10 bit output?

to send 10 bit to the GPU driver you have to set your display to 10 bit.

An issue with Madvr:

If I disable DX11 and set video to full screen, screen becomes black and cursor blinks. I have to kill the app. Problem is that if I restart the app, video acceleration is disabled, even if I enable DX11 again. CPU reaches 90% usage. Have to restart Windows.

I know this is probably going to sound silly but could it be an idea that after madVR installs the bat file runs a seperate small exe to check what GFX card driver and OS version is installed. Then gives a message about known issues with that driver /setup combo?

HP Laptop
Windows 10, ver 1709
Intel i7 6700HQ, 16 GB RAM, GTX 1060

Things is Madvr did not have tearing at all till now. Something with the latest update perhaps?

Unfortunately Gsync monitor is problematic. Some 2D games have issues running full screen (40 fp) or refuse to run at all

Because it supports only 40 and 75 hz. I have to use custom resolutions for 60hz but it doesnt solve the issue. Even with 60 hz there is tearing

Thank you for your prompt answer!

Nvidia display driver is set to RGB / 12 bpc / full dynamic range
madVR is set to PC levels / 10 bit and HDR passthrough

What exactly do you mean by "set your display to 10 bit"?

ok, that does seem to work, however I thought I'd be able to preserve BTB now i'm using 444F-RGB but I then remembered my desktop would be crushed if I did which opens up an new set of problems. Seems to best option is to set FULL FULL FULL as suggested here.

What are you using?

actually, i'm going to leave it on ybcr 420, my system is stable at the moment and I have a great picture with nothing to worry about, this introduces a new element if my system becomes problematic again . I'm going to wait to see if the FSE and black screen issues get fully fixed before I try a new setup but thanks for your advice, I wasnt expecting that to work to be honest, didnt think it switched colour spaces, only resolutions and hertz.

Cheers Manni / huhn

i mena this:

@mclingo here is the madVR FAQ: https://forum.doom9.org/showpost.php...16&postcount=2

and about the black screen. this is a MAJOR issue and the reason i don't have a RX 480 anymore. contact the AMD support and make sue they fix this and yes i contacted them too i simply didn't accept a fundamental broken product for more than 6 months.

i have both, i still cant my 1050 stable with 3D, sometimes it works, sometimes I get a black screen, sometimes it just plays in 2D, my AMD card work fine every time, only problem iissue it crashes my PC on stopping sometimes if I don drop to 1080p desktop first. I dont watch 3D that often so its a good enough workaround, all my 2D, 4K and 4K HDR plays fine now, no issues at all.
