getting HDMI loss / black screen all over the place coming out of movies, this is something that only used to happen coming out of 3D movies, now its happening in eveyrthing, mainly in KODI DS, only change i've made on my PC is MADVR update, however i've reverted back and they remain so its broke something on my HTPC, gutted.


edit - might have fixed this with a KODI DS install straight over the top, could be unrelated to MADVR.

madshi could maybe improve this. I know there is a new Panasonic Blu-ray player that gets along well with this setting with many displays. I have seen several examples where tone mapping the image before the display results in an image with more highlight detail with any display that clips too much at the top.

The tone mapping was optimized for HDR -> SDR, so I don't know if it was tested that much with a PQ output. You are probably compressing reference white (100 nits) too much at 400 nits. It would likely work better if you could find a higher value that only compresses the top of the curve to better match the bottom of the PQ curve enforced by the LG. Your display must be brighter than 400 nits in HDR mode.

Hi!

Just curious. How did you display the detailed rendering in ms? ctrl J doesn't show this

Thanks

made a clean madvr install.

tested on 2 monitors, one with DVI - and one with VGA..(yes one monitor still has VGA)

and this is what i see:



dont mind my shaders down there..haha


Is there a screenshot somewhere to see how its supposed to look?

Only active when the OSD is being displayed.
Create a empty folder named "ShowRenderSteps" in the madVR folder and you will get a more detailed OSD.

If it changes driver by driver then it's *very* unlikely to be my fault. Complain to AMD, please, not to me...

To be honest, I haven't really tested "process HDR content by using pixel shader math" in a long while, I didn't think (m)any users were using it. I'll check if I can reproduce the problem(s) here.

Is there a specific reason why you're not simply using "convert HDR content to SDR by using pixel shader math"? The "process" option has the potential problem that although madVR already did all of the tone mapping work, the TV might double process (= damage) it.

From what I remember, you said it only occured in very specific situations, e.g. using D3D11, but not when using D3D9 etc. So why don't you simply use settings that make the problem go away, like using D3D9? As I said before, it's *very* unlikely to be a bug in madVR. So I'm hesitant spending a lot of my precious development time on that, when I could use the same time to do other things.

Maybe, but not planned soon. I did it for Nvidia because I had to access the private Nvidia API for the new "report BT.2020 to display" option, anyway. Unfortunately AMD's private API doesn't support this "report BT.2020 to display" functionality, as a result I didn't have much motivation to spend several hours just to add some information to the OSD.

The Nvidia API is buggy there.

I don't understand what results in so dark images with the new madVR0.92.16,either.Thank you all the same.Restart the old madVR0.92.14,All seems so normal as usual.
By the way I don't know if most of HDR fans here will have the same problem

In my particular case, HDR would show on the TV as being active but in reality it wasn't. If I activated the Windows HDR/WCG setting before starting the player, then it'd play. This ended up being a driver issue with the new 4xx nVidia driver rather than an issue with madvr. Once I downgraded the driver back to 399 I've had no further issue with HDR in any of the madvr versions.

Is your image truly switching on HDR and is dark or is it not truly activating HDR?

@madshi
First of all thank you,master ,for your reply.
second My TV set has HDR feature. So i don't think i will use any feature of HDR conversion to SDR.The purpose of using the feature 'process HDR content by using pixel shader math' is to improve image quality of HDR movies.Thank you again,master

Surely。the HDR feature is activated although the HDR image is so dark.I've installed 411.xx driver.but it doesn't work yet

bugged in term of not working at all or something like nonsense reports?

if it is not utterly broken and reports "something" i would like to test it on a couple of screen of cause only if you still have a version with it lying around.

It's like I said in my post, processing via HDR -> SDR means my TV stays in SDR mode which has a lower peak brightness than the HDR mode. It also means I have to change my SDR mode picture settings on the TV for the HDR content (Bt.2020) and then back again when I'm playing SDR content (Rec.709) instead of being able to have separate SDR and HDR picture modes like I do with the passthrough option. I could be understanding this wrong, but I had to change a lot of settings to make the HDR tonemapped to SDR image look right on playback compared to how I've had the settings for my SDR content.

What is the "send HDR metadata to display" box for in this mode, by the way? I kind of assumed it was meant to submit the "new" HDR metadata that madVR maybe generates from using it's tonemapping algorithm to the TV. A lot of this was just my assumption that this mode was to put the TV into HDR mode. I'll play with the SDR conversion method and putting Windows into HDR manually via display settings. My goal was essentially to replace LG's tonemapping method with the one in madVR for HDR display. I had not considered the TV might doing a second process like you describe.

Increasing the nits doesn't fix the super strong red hue, but they have to be that low to avoid the intense black crush that also happens with the HDR process setting. It was also set to 150 / 400 to make it easier to see the red problem in the photos.

Playing back 720p HD mkv, run into new issue since (including) madVR version 0.92.15 (WASN'T present with 0.92.14 and reverting still works).

When I engage vobsub (idx/sub) subtitles via XySubFilter in Zoom Player, video freezes though audio continues. I don't get any subs. In fact the freezing only occurs at the point when the next sub would have appeared. It's non recoverable - have to restart player to restart video.
VobSub filter still works.
Plain text (SRT) subs still work in either sub filter.

Using AMD RX460 with Adrenalin 18.9.2 (latest) driver. Output is direct HDMI to Samsung monitor, 1920x1080 resolution.

Sub filters previously installed (as pair) via ZP Install Centre - reported as 3.1.0.747 via that installer.
VSFilter.dll (VobSub) shows 3.0.0.306
XySubFilter.dll (XySubFilter) shows 3.1.0.747
LAV Decoders 0.72.0 (video using DXVA2 copy-back)
Zoom Player is MAX v14.4b1 (latest, ZP is a 32-bit app)

----

UPDATE: same issue occurs on different PC w/ same software setup, but with older AMD Radeon HD5670
(again, reverting to madVR 0.92.14 works)
UPDATE2 (2018-09-21): issue confirmed in BOTH full-screen and windowed playback
UPDATE3 (2018-09-23): issue confirmed using LAV in BOTH (none) and DXVA2 (copy-back) acceleration (or not) modes
UPDATE4 (2018-09-23): issue confirmed on laptop w/ same software setup, but uses Intel HD GPU

@madshi, i'm not complaining with you, neither finger pointing. i'm just wondering if maybe it's possible to fine tuning something madvr side to make HDR auto switch more reliable.

AMD guys, better stay away from driver 18.9.2! Can't use D3D11 10bit mode in madvr with latest 18.9.2. Reverted back to 18.8.2 and it works again.

Working fine here.

EDIT: What doesn't work for you exactly?

the 10bit windowed mode in D3D11... only works with 8bit with latest drivers

@Sunset1982 Even with nvidia, windowed mode is 8bit "D3D11 windowed (8 bit)", but as soon as you full screen it, it turns into "D3D11 fullscreen windowed (10bit)". Is this not the expected behavior?

For what it's worth: I still had the render queue not filling correctly issue with 0.92.16, it only worked in FSE. However, it seems to have disappeared after a Windows restart. Maybe you want to keep an eye out on this.

Edit: The CPU load with HDR pixel shader conversion is also a bit high, especially with highlight reconstruction.

Wooowoo!! I've started to try all possible combinations of amd driver setting. And finally i managed to have back hdr autoswitch with 18.9.2. i have to set desktop at 12 bit. We will see with future drivers updates if it keep working.

As usual madshi was right.
