Just to report that 417.71 doesn't work in passthrough with 1080ti, at least in 4K23 12bits RGB full (custom 23p res with CRU). It sends bogus metadata. See https://forum.doom9.org/showpost.php...ostcount=54551

You might need a different table for GTX and RTX, and possibly for bit depth (8 vs 12), as drivers don't seem to behave the same.

Tested on Win 10 x64 build 1809, GTX 1080ti. HDR passthrough still broken (wrong metadata) but everything else seems to be working.

12bits at 4K23 RGB Full survives a reboot as long as it's your default refresh rate.

Which latest driver version of Nvidia has working HDR passthrough for users who use that.

398.11 is the last working driver for HDR passthrough, anything later has the bogus metadata issue.

Should add that later drivers will switch into HDR fine, and displays will switch into HDR, however any driver later than 398.11 is sending bogus metadata to the display.

I'm using 416.81. It switches HDR mode including at panel level (auto increases backlight, etc.) with no problems and behaves with 3D stereoscopic switching perfectly as well. This includes the resolution change bug from 2160p to 1080p and vice versa postage stamp issue many experience. I do edit the installer to use 388.59 HD Audio driver because every audio driver since has multichannel problems under certain conditions. I've tried every driver release after these and none of them passthrough HDR to all players and the audio problem persists. DVDFab Media Player v.3 to be exact. Using madVR compatible players like MPC-HC/BE were also hit and miss until using this combination. A good fallback if you don't want to edit the installer is 385.28, an older driver. The advantage to using the newer combination is frame drops that you can count in madVR's OSD. For most that do not use a reclock method of some sort, you will get a frame drop every 4.37 mins. This has always been the norm for nVidia. The improvement using this newer combo is the drops decrease to one every 13 mins or so. This improvement is only using 3D though. 2D still drops one every 4.37 mins. Many are using newer drivers and reporting no problems except they are confined to very limited use with very specific caveats. This combo is much more diverse imo.

Maybe you should add this link next to the description for 398.11 to explain what this is the last working driver: https://forum.doom9.org/showthread.p...44#post1865444

can someone test WFS 10 bit for banding especially at 12 bit or even better 10 bit RGB output on nvidia?

you can test it with this image: http://www.bealecorner.org/red/test-...ient-16bit.png

it's not easy to do but there is a trick that will help send 12 bit RGB (a really good 1080p screen is mostly better) use MPC hc/be use WFS 10 bit with the image and and now right click.
when you right click you should see heavy banding when it switches to 8 bit output and shortly after that it should disappear and should have less banding or no banding in 8 bit WFS mode so it should have less banding then WFS 10. FSE 10 bit should show less banding too.
tested on 419.17 if this is a GPU driver bug everyone should be affected.


capturing the image should be the easiest way to show it but that's not really possible.

How do you set 10bits RGB out on nVidia? The only options at least here on a 4K display are 8bits and 12bits.

The display must support 12bits natively in order for 10bits content to show without banding when 12bits is selected.

Recent JVC projectors support 12bits from the input to the panels, but not many displays do. Most support only 8bits or less, a few support 10bits, very few actually support 12bits natively, even if they accept a 12bits input.

So if you send 12bits to a panel that doesn't support 12bits, or only supports a 12bits input but then dithers to the panels because they are only 10 or 8bits, then you get this minor banding you are seeing sending 12bits to your display.

Are you 100% sure that your display supports 12bits from the input to the panels, through the whole internal chain, the way recent JVC projectors do?

I don't see the point of the test if you're not asking people to test on native 12bits displays.

I can test it this evening but with the old driver (v385.28) set to 12 bits (no 10bits) and madvr set to 10bits. My 1080p TV (8bit+FRC) accepts 10 bit signal, that's how I use it.

displayport monitors.
10 bit PC dispalys are a thing for a very very long time now.

which display even does processing at less then 12 bit?

not sure why this would matter or why you think that's the case.

dithering will not produce banding that's the point of dithering.
Quote:

my TV is labelled as a 10 bit 120 HZ panel (orion if i remember corretly) i'm pretty sure it's 8 bit +HI FRC
there are no 12 bit displays even the most professional displays normal user can buy are 10 bit and i'm talking about grading displays here these often have 12 bit hardware LUT or better so sending 12 bit is clearly intended.
12 bit input support is a thing since for ever.

so even if JVC supports 12 bit presentation it doesn't matter even 8 bit can trick human eyes and measuring device to thing is 12 bit plus. and that why the only way to figure out if a end device (not a display anymore we talk about projector now) can do 12 bit is checking the part if it supports 12 bit direct input from the processor words from a manufacturer are not enough.
checking for 12 bit input doesn't tell you anything and using measuring device can't figure it out and the human eye well it'S the human eye.

if your logic of dithering 12 to 10 will create banding then madVR is the biggest banding producing program ever made by using 16/32 bit to 10 bit dithering i'm pretty sure we both can agree that'S not the case.

BTW there where devices that clearly accepted 12 bit for the panel(you can check the parts) and these devices biggest short coming was bit deep related. i'm talking about Panasonic plasmas they often support 12 bit for the panel which is pretty worthless thanks to the noise level well i guess this is faster/cheaper then dithering before which was not a huge thing back then.

as you said before nvdia doesn't like the idea of sending 10 bit using HDMI. so we do it with 12.
and as 10 bit FSE doesn't show banding but WFS for me i clearly see a problem in WFS 10 bit.

or with other word i can easily see the difference between 10 bit dithering and 10 bit no dithering which makes it very clear that my TV can show 1024 steps as a 10 bit panel would be able to do

Good find, @huhn! I could recreate the issue. (see my signature for more details on the setup I use)
- 1080p 10 bit (8bit+FRC) TV
- nvidia v385.28 driver is set to Full range, RGB, 12 bit
- MadVR is set to:
-- "10 bit or higher"
-- "Ordered dithering" is On!

It didn't matter whether I set dithering to None or Ordered!

I couldn't really tell the difference in banding between FSE and WFS, I could clearly see it in both.

It does for me, see above.

Interesting thing is that using the same TV with my old laptop (optimus system, with intel driver + win8.1) I didn't have this issue with 10bit FSE.

Here's also a good tool if you don't want to install too much crap which are bundled nowadays in nvidia drivers such es telemetry https://www.techpowerup.com/forums/t...-alpha.249085/
Remove your old driver with DDU first https://www.techpowerup.com/forums/t...-alpha.249085/

if you see it on both FSE and WFS you should assume it is the TV.
