madVR - high quality video renderer (GPU assisted)

[huhn]

on older LG and samsung it was typical to only support PC mode at 30 and 60 HZ (30 was added where HDMI 1.4 was still a thing so new 4K TVs).

so it does not matter if can do it in theory if it does not in practice this is only relate to internal subsampling or not they still always accepted 444 or RGB but they throw that away.

not been able to properly display 23p is a different issue. samsung is well know to be unable to do that on many screens and be very inconsistent about this but at 120 or 144 it has to do it properly it can't do 3:2 or other image crimes.

[tp4tissue]

@tp4tissue Why is that a problem for the Samsung? 5x23.976 is 119.88. Doesn't it internally do the multiplication itself if you feed it the source rate?

The cadance isn't a problem. But it's the way samsung locks out its modes relative to PC-use.

For example, it only allows graphics-mode but NOT filmmaker-mode or movie-mode w/ 4:4:4 input @ 60/100/119/120/143/144.

It also locks out 20 point gamma on pc graphics mode.

It has black crush on 144hz mode, but not in 120hz/100hz modes. So they used a different offset.

Just so many inexplicable lockouts / weird decisions. If it wasn't for the fact that color volume is awesome, and it's reasonably accurate out of the box, I would return this TV for bad software alone.

[Sunspark]

Have you tried turning on HDMI UHD Color for the port? Samsung generally wants it on to use 4:4:4 in movie mode.

Yea, it kicks you out of 444 when 23/24 is engaged.

[Manni]

Did you try disabling PC mode and game mode? All works fine at 100p for 25p/50p, 119p for 23p/29p/59p and 120p for 24p/30p/60p in FMM and MM

[huhn]

samsung is know to sub sample outside of PC mode. even in game mode it is not unusually that subsampling is applied.

pretty much all TV are known to do that.

i take that's not the case anymore?

[Klaus1189]

If the display does 23/24/25/50hz at 444, you're set. The 1060 will be fine.

The higher refresh rate doesn't matter for movies, except in the case where the TV will not allow 444 pc input. Like on Samsung. God damn Samsung. It allows 444 only at 60/119/120/143/144.

What about 50 Hz and 100 Hz?
What Samsung model do you use?

[tp4tissue]

50 and 100 works, I was just lazy and didn't type it out. 23/24 is when it kicks you out. I have the 90c

Are you talking about recent HDMI 2.1 models with a full 48gbps bandwidth?

Anyway, it doesn’t seem to be the case here at 100+, at least when I check with patterns. It might do so at 60 and below, but I don’t care about that because I use 100p and above to disable entirely the TV processing.

Also frankly even if it did it makes little difference with 4:2:0 video content. It would make a difference with desktop/games, but I don’t really care about that.

[huhn]

bandwidth is irrelevant in general "all" TV subsample and do other stupid stuff outside of PC mode/game mode. it depends not like i have checked the 2023 series at all. in the past samsung disengaged PC mode out of 30 and 60.
PC mode usually disables a lot of processing too if not all.

and my chroma obsession is next level anyway combined with my insane close sitting position...

a lot of LG OLED TVs are known to totally trash HDR in PC mode just the usual TV stuff... so it is sadly not generally a recommendation for most accurate and creators intend.

Bandwidth is relevant if you’re talking 4K100p and above as I did. Clearly you can’t keep 4:4:4 chroma if you don’t have the bandwidth to do so above 4K60.
All I can say is that 4K119p works here with PC mode and game mode disabled. There is no processing from the TV.
Obviously I’m only talking about recent models with HDMI 2.1 and I don’t care about LG, we were talking about Samsung.

[huhn]

HDMI 2.1 is standard in TV for like 4 years now and TVs had it in 2019.

the refreshrate doesn't matter in the past they where always subsampling except in PC mode (which could be disabled on Samsung depending on refreshrate as far as i know only Samsung does this).

even if they have the bandwidth they subsample it's just what they did. maybe motion interpolation only works at 422 i don't know but that's what they did in the past. if they stop doing that nice.

these information is hidden these days allm and such made stuff different and testing got worse.
the rtings review makes clear the LG c4 does need PC mode but for the Samsung 90c they say it can do it but nothing else. 120 is listed with 444 support but 144 is not... (bandwidth is not the issue)

do not forget samsung can motion interpolate in game mode. cause samsung...

Come on, bandwidth obviously matters if it’s not enough to allow 4:4:4 at high frame rates. My S90C, unlike the S95C, has full 48gbps bandwidth. I AM ONLY TALKING ABOUT RECENT SAMSUNG MODELS.

As I said, I have disabled both game mode and PC mode. It works fine at 100-119-120p and Samsung processing is entirely disabled. I’m doing this as a workaround for the motion bug introduced by Samsung in FW 1410.

Anyway, my intention was not to debate about these obvious things with you and bring up old models and other brands. I was only making a suggestion that it’s worth trying disabling PC mode and Game mode at 100p+ for video content and see if that resolves the OP’s problem.

I’m out of here. :)

Technically, it still has dithering, so the processing isn't disabled disabled, but yea it doesn't do any really funky stuff. :D

Glad it helped :)

I send 4K119p (for 23p content) in RGB 10bits, so there is no dithering I can see from the display (obviously the renderer dithers from the internal 16bits to 10nits). This is with a 3090. All I know is that in that mode, the TV processing options are greyed out and the motion bug introduced in fw 1410 is gone, which shows that at least *some* processing is disabled.

[leeperry]

Hiya, having quite a bit of a hard time getting any fullscreen to work on updated W11 with AMD Ryzen 5500GT APU, messing with various options always ends up in a black screen, OTOH windowed works. Anything I'm missing please? :o

[huhn]

FSE is simulated don't use it.

[leeperry]

sadly FSW doesn't work either, will keep digging

[huhn]

you may used a time bombed version that is timed out?

it doesn't sound like a general black screen and windowed works that should be a clear no.

206-207 has horrible issue avoid if you are using that.

[leeperry]

mVR version? I use latest mVR from this OP + W11 updated fully and legit, it's even activated and other VR's work in FS.

[huhn]

try 205 https://www.videohelp.com/software/madVR/old-versions
this version will work for another ~2 month or something.

the release version has issue with win 11 a black screen isn't usually one of them.

if it doesn't work give MPV a try.

[leeperry]

FSE is simulated don't use it.
are you saying that FSE doesn't matter over FSW anymore on W11?

[huhn]

it's also windowed now. this was changed in win 10 at some point.
FSE does not exist anymore by default windows just lies to the application and doesn't give it an exclusive surface.

you can try compatible mode and disable full screen optimization to get the real FSE back but that can also fail spectacularly.

[leeperry]

Fair enough thanks, any official word from madshi about this please? No bro-science? ^^

Apparently my black screen problems were partly due to the D3D skin of PotPlayer because as much as it worked wonders in D3D9 on W7, it won't work in D3D11 on W11 and mVR goes black screen in D3D9 on W11 so I'm trying to have it fixed in PotP but madshi appears AWOL so this might be a long shot and FSW does appear to work fine.

[huhn]

feel free to add it to the tracker. i have no clue if he knows about that.
this is unlikely to change.

i know other major bugs in the newer version it's just to much work to report just so it can say there forever.

the newest version broke SM so hard it will trigger epilepsy.
the current state is will be fixed in the next version which could be tomorrow or in 6 months.

mine subsamples outside game mode (it also subsamples in game mode! outside of 144 hz where it has other issues...).
Samsung removed PC mode at least i can not find it and subsampling can be beat other ways.

but all of this has to be taken with a huge grain of salt because mine is running 1402 and tells me that is the newest it will not update to 1410.1. i expect wonders from an update

if i change refershrate it will literally change the picture mode i'm not going more into this this has to be one of the worst bugs ever. nothing works the 20 point can not be used in game mode and it placed in the middle of the screen anyway.
it clips so many black level that displaycal doesn't let me calibrated because the difference between 0 and 16 is so low it thinks the level should be wrong...

game mode has more picture modes then normal mode they are just hidden for some reasons.

edit: game mode there is no PC mode

Don’t update from 1402 if you have a S9xC, 1410 and more recent break motion and there is no way back.

[huhn]

just like you i will use 100-144 hz where the issue will not matter.

i really hope it fixes other issues. this is really broken. it seems to sub sample in linear light making normal Chroma test pattern not that useful.

it currently clips 8 black level barely anything in there to fix that. i mean LG had a 22 point where the ext 22 points where just for close to black changes here i have a 2 point which is a 1 point calibration a tint i might say...

Which pattern do you use to test chroma? I used both S&M and the brown fox and I couldn’t see any damage with PC mode and game mode disabled (both are present) at 100+ fps. I don’t use desktop/gaming, but I didn’t notice any chroma issue on the desktop itself and video content looks pristine in FFM/MM.

the screen is completely insane in terms of presentation and procession.

in filmmaker i got blue and pink lines i have no clue how the TV did that.
game mode
perset standard (in custom the color space is messed up i guess)
144 hz
sharpness 10
and the other stuff disabled like CR enhancement and so on.

gives me accurate 4:4:4 on a sub sub pixel level. i only test SDR.

isn't S&M an encoded disc? that means the chroma needs scaling to check placement madVR does this wrong for UHD and the old S&M disc did chroma wrong not following the spec they may fixed that in the new one but...

How do you interpret the results of the Chromares pattern? What should it look like for full 4:4:4 chroma?

[huhn]

you should be able to see the 444 name and notice the blue sub pixel in the pink part around the 444.

the checkboard pattern around the 444 should have a similar color like the boarder which is solid color. it could be a bit darker or lighter then the boarder this depends on your gamma.

422 part should show you blue and pink lines on the top and bottom of the letters because they are 2 pixel there. a skilled eye will also see the individual liens in the 422 if you are close enough. no need for pixel peeping.

this pattern does not work when any sharpening is done like the CR enhancer and sharpness does.
for sharpness i use this:
http://www.lagom.nl/lcd-test/sharpness.php

you need to get far away from this pattern so your eyes can't see the individual pixel.
i open both of them in paint and leave them as is yeah quite small these days.

i'm not even sure we have the same screen...

Thanks. Did you try to use the exact same settings I am using in FMM at 4K120 with pc mode and game mode disabled? What is your exact model and size? If under 77” you might have a gen 1 panel. Let’s discuss calibration in my thread as I think it’s fairly off topic here (apologies everyone).
I’ll just post my chroma results here when I have a chance to check it with the chromares pattern.

144 HZ it seem to be able to do 444 outside game mode.
CR enhancer and other settings will result in a subsampled making 444 checking really hard on this screen.
i only have entertain and graphic mode at 144 and currently there is no point in not using game mode at this refreshrate.

in filmmaker mode at 60 HZ i got the chroma test pattern to flicker and sharpness to only change the left side of the screen when i put it at 20 for testing.

i will do 120 HZ later there are a lot of setting i have to redo which could give me a false negative.

it was sold as an GQ55S90C this version wanted to default to "Niederländish" netherlands i guess in english.
this is is not the german or english edition i guess.
the internal name is QE55S90CATXXN. that supposed to be Austria.

You might have a gen1 panel if it’s a 55”. These might not measure as well, but you would need to measure FMM at 23p with my settings to see if it’s game mode ruining your calibration (it probably is, that’s why I don’t use it).

I can confirm that as the S&M and quick brown fox patterns suggested, I get full 4:4:4 with the chromares pattern at 119p in 4K in FMM mode with game mode and PC mode disabled. No idea what it does outside of that, I haven’t tested it. Sharpness at zero as per the settings posted in my thread.

[huhn]

game mode has not negative effect on calibration at 144 HZ.

FMM 120 doesn't exist here i can't even do more then 60 hz with disabled game mode. yes you can disable it after entering 120 HZ but still no FMM. so i can't test what you are asking for.

You need to also disable PC Mode in order to get FMM.

[Manni]

To disable PC mode, press input, edit your HDMI input, and select anything but PC Mode (I selected Home Theatre System).
I can only talk about 4K119p HDR FMM with Game mode and PC mode disabled, as that's what I use for playback (well, 100/119/120 depending on content refresh rate) and calibrate for.

[Manni]

Just tested with the OS set to SDR, and I only get 422 in SDR 4K 119p. That will explain why I get 4:4:4 in the QBF pattern and the S&M patterns, as I'm now using OS HDR to limit the number of HDR-related HDMI syncs. JRVR plays SDR content fine within HDR since build 55.

So try to enable OS HDR and see if you get better results chroma-wise.

[Asmodian]

That will explain why I get 4:4:4 in the QBF pattern and the S&M patterns, as I'm now using OS HDR to limit the number of HDR-related HDMI syncs.

So... how do you know you are getting 4:4:4? In my experience the QBF and S&M patterns are not reliable.

I think your display is converting to 4:2:2 internally with better than expected results, but not true 4:4:4. I noticed this behavior with my Samsung S95B (1st gen QD-OLED).

So try to enable OS HDR and see if you get better results chroma-wise.

Calibrated SDR with the OS set to HDR?!? How does that work? :eek:

Read the last few posts, I used chromares to validate 4:4:4 in a very specific configuration (4K120p 10bits HDR no pc mode no game mode). Also I have an S90C (2nd gen QD OLED), more recent than your S95B and with full 48gbps HDMI 2.1 (no crappy OTB limited to 40gbps).

As explained, SDR within HDR works fine with JRVR since MC32 build 55. When OS HDR is enabled, JRVR converts rec-709 BT1886 to bt2020 PQ. Off topic here, of course. :)

you technical only need to convert to sRGB and give that to windows and that's it.

you can also just create a 3D LUT while it is in that mode by not using madTPG.

what a mess.
first disable game mode then disable PC mode or it will reactivate PC mode by autodetection. (no game mode auto was not used) or maybe it just still sticks to PC when i selected blu ray player.

120 HZ FMM messes up chroma the sharpness has no effect on the chroma image.

OS HDR ahh well i don't have win 11 to dial that in so the results are orange i might say...
my best guess is 422 but the pattern doesn't work because of SDR to PQ conversations.
sharpness has an effect here.
the pattern falls apart so it needs to be redone with PQ in mind and loaded as HDR or encoded as RGB.
the encoding is no problem for me the redoing in PQ is outside of my skill rnage.

sharpness 0 is clearly neutral in FMM OS HDR while it is 10 in graphics PC mode/game mode. this is very odd for samsung TVs 0 is usually the way to go.

very temporary decision for me is clearly PC mode game mode and dialling that in. the screen is very very stable a 256^3 3D LUT in SDR mode should be an easy task.

40 GBPS is enough for 4K 120 10 bit(12 should work too i'm not doing the math) so there is no need for it on 120 HZ TVs are just as good with it as without it.

Spears & Munsil is more of a chroma positioning test (it was testing mpeg2 placement in the past) than a resolution test. it's a disc it can't really test resolution.

my best guess is 422 but the pattern doesn't work because of SDR to PQ conversations.
sharpness has an effect here.
the pattern falls apart so it needs to be redone with PQ in mind and loaded as HDR or encoded as RGB.
the encoding is no problem for me the redoing in PQ is outside of my skill rnage.

sharpness 0 is clearly neutral in FMM OS HDR while it is 10 in graphics PC mode/game mode. this is very odd for samsung TVs 0 is usually the way to go.

very temporary decision for me is clearly PC mode game mode and dialling that in. the screen is very very stable a 256^3 3D LUT in SDR mode should be an easy task.

40 GBPS is enough for 4K 120 10 bit(12 should work too i'm not doing the math) so there is no need for it on 120 HZ TVs are just as good with it as without it.

Spears & Munsil is more of a chroma positioning test (it was testing mpeg2 placement in the past) than a resolution test. it's a disc it can't really test resolution.
No idea what’s wrong your end. All I know is that chroma is fine here in 4K120 10bits OS HDR enabled pc mode disabled game mode disabled FMM. It’s not fine with OS HDR disabled. I think we’ve been off topic long enough, so I’ll just bow out.
Yes 4k120 10 bits is enough for FRL5, but some displays use DSC even though it’s not necessary, which can cause issues. Not the case with the 77S90C using the settings above.

I just "upgraded" from a 1070 to a 3060 and it introduced stutters in MPC-HC + MadVR on 60fps videos. I traced it down to the new driver defaults which defaults to "power management mode: normal" instead of "max performance". In other words, if I set "max performance" mode the stutters go away completely.

I just wanted to know if it's the same for others, because max perf uses +20watts and frankly it's kind of stupid that you'd need to be running a 2GHZ GPU in "max performance" mode just to render a single texture/raster at 60fps with no 3d graphics or anything that would strain the GPU.

I tried other renderers it still stutters unless I set max perf mode in NVidia driver. Dumb!

Am I the only one with this problem?

Feedback appreciated

You set maximum performance for the player only or system wide?

Either works for me. Currently I have it max perf globally and mpc-hc.exe is set to "use global setting".

It's just super disappointing to not get that 20watts power saving when the GPU barely breaks a sweat playing videos. In theory it should easily be able to do it at a clock speed of 300Mhz.

I just spend the last couple of hours iterating through every combination of madvr settings relating to this, like the backbuffer size/type, flush behaviour, dx9/dx11, exclusive/windowed, desktop composition, then a whole bunch of settings in NVidia Inspector relating to sync and other power modes. No improvement. It seems to stutter slightly less if I use a very short backbuffer queue and set them all to "don't flush", but it's still like 1 stutter every 20-30 seconds or so.

Oh and one really weird thing is if I open the 60fps test video in Firefox browser it plays flawlessly and GPU downclocks to 200Mhz the whole time. In NVCP the default Firefox.exe profile doesn't expose the power management mode but NVidia Inspector reveals it to be "Adaptive" which is basically the same as the max power saver mode. So maybe it's an issue with MPC-HC.exe or DirectShow or something. I'll be installing a new motherboard and CPU next week.
