Whenever i go into a fullscreen window or exclusive mode my black level is completely crushed. When in "Windowed" mode it looks ok. Here are my settings now: 10 bit output in AMD drivers, Full RGB, link assurance off. MadVR set to output Full RGB Projector set to full RGB I've been playing with AMD driver versions as well and that doesn't seem to make a difference. https://imgur.com/a/lj7y3QV You can see this in the video. When the seek bar is active MadVR is in "windowed 8 bit" mode and the black levels look ok. Once i let the seek bar disappear MadVR moves to "fullscreen windowed 10bit" and the black levels are crushed. For some reason 10bit output just seems broken. Thanks for all the suggestions of things to try! I would love to get 10bit output working correctly, i am pretty sure this was working fine a few months ago... |

i don't need a video or an image i know what you are talking about. you have done a very good explanation.
i currently don't have a AMD card connected to a system that supports more then 8 bit input so i can't try to reproduce it. so just stick to 8 bit for now the difference is very minimal anyway. it will break AMD HDR API but you are on a projector anyway. the AMD driver are sadly currently very very buggy. there is just one thing you could sahre you are not using the windows OS HDR toggle? so a laptop with a 1060 is now an rx 580?

the composition rate bug usually comes from using 2 screens. workaround is overlay rendering the next windows version has a planned change to minimise this issue but it still not fixed. FSE was supposed to fix this to but that's pretty much fake on windows 10. |

It's definitely is starting to feel like an AMD driver issue, my guess is one of the updates to Windows and something screwy on AMDs side messed it all up.
I am not using the windows HDR setting, I'm letting MadVR do all the tone mapping so I only ever output sdr on this HTPC. For now I'll leave it all as 8bit, and maybe switch to a Nvidia card in the future. Thanks! |

what about the stuttering with directx11 that goes away if I use dx9. that also seems like a bug. as far as i remeber there inst anything to see in the stats. no glitches og frames or anything lost. it just stutters

you can try a low present at advanced value of 2-3 to make does the trick.
there are multiply reports of turing cards showing problem with the normal 8. but again as long as the composition rate mismatch is still there you are sadly playing with fire. d3d11 doesn't have overlay rendering. |

Put everything to full, turn off your 3d lut, and all your calibration settings. Reset the gamma table in the GPU loader, make sure those things are not doing corrections, because you may have created them in the wrong display state. <so the corrections are borked> Also select disable gpu ramp in the calibration tab If it's still doing the crush, try full screen exclusive mode.

[QUOTE=GoodGravyMan;
Thanks![/QUOTE] I'm not convinced its a driver issue, I think more people would have noticed this, feels like an issue with your setup as I used an RX580 for ages and never had this issue, however I was nearly always just using 8bit. Problem is there probably arent enough people here with AMD cards that are using a full 10 bit setup as its just not necessary really, however OLDPAINLESS does have a similar problem with the latest driver where when he seeks it drops to what looks like limited output, but he's using a NAVI card. I'll have a play with 10 bit and see if anything crops up.

GPU gamma ramp is disabled in the MadVR settings already. Exclusive and non-exclusive mode also do the same thing. I don't remember setting anything with any gamma table in the GPU loader, how do i reset that? |

yes that does sound the same, which windows version are you on?
Thinking back there was a time where I've had something similar with my RX580 but it it always when I dropped out of full screen when using FSE, it was like MADVR was dropping back to limited as coming out of full screen was breaking the processing chain. With later drivers I didnt need FSE. If you are getting it with FSE turned off then i'm not sure whats going on. I still cant help feeling both of you have got something in your chain causing this, whether its a duff cable causing a bandwith issue or a setting in you video player, lav or MADVR settings I dont know but here are my old settings when using RX580. Windows 1809 graphics set to 8 bit full RGB but link ass off scaling full panel MADVR everything (relevant) unticked unless stated PC levels - 0-255 native bit - 10 bit (not auto) calibration - disabled diaply modes - 2160p23, 2160p24, 2160p25, 2x160p30, 2160p50, 2160p60 HDR 113 beta - output in HDR enabled. use DIRECT 3D 11 for pres - ticked trade quality for performance - all unticked apart from comp HDR luminance as my RX580 couldnt handle that Lav - D3D11 installed players for MADVR: KODI DS better GUI version - windowed mode turned off MPC-HC with external lav filters used

Is there a way to take a screenshot of a video upscaled with NGU in a MPC-HC window? Full screen is easy with Print Screen, but when I use MPC-HC to capture a window, it seems that the video is upscaled with bicubic or something else.

have you set your upscaling method in screen shots section of MADVR?

Yes thanks, I had forgotten that, but you still can't tell if it's using very high, high, medium ...
EDIT: It seems that at least for "sharp" it uses "high" although the result is not identical. I wish I could use "very high". Last edited by Alexkral; 19th March 2020 at 00:15. |

I am running Windows 1903
outputting Full RGB 10 bit from the AMD drivers link assurance is off GPU scaling is off MADVR (92.17 + beta 113): Properties: outputting PC levels 10bit bit depth Calibration: I normally have calibration with LUT enabled but i've tested with calibration disabled and i see the same thing. Disable GPU gamma is enabled. Display modes: 2160p23, 2160p24, 2x160p30 HDR: tone map using pixel shaders. i am not outputting in HDR format rendering: delay playback start use Direct3d 11, with vysnc checked everything else unchecked only item checked in trade quality for performance is the HDR luminance as well LAV 74.1.34 D3D11 with the GPU selected, making it copy back. I have tried native and that doesn't make a difference. "RGB output levels" is set to untouched. I am using MPC-HC with external LAV filters. I've also tested MPC-BE and that does the same thing. One thing i have noticed is that when i am full screen in 10bit my projector says that the incoming video signal is in BT2020 when playing back SDR BT 709 content. When in 8bit mode it remains blank. I think i read in the driver thread there might be an issue with Windows 1903 and it correctly outputting BT2020. Maybe this is related to what I am seeing. |

bt 709 and bt 2020 have nothing todo with levels.
and only the video driver is in control to send this type information. not saying something else told the driver to do that but it is is control to do that. there is no point in measuring anything this is an very obvious level issue. if you want to see if the 3D LUT is related press control+shift+3 or control+alt+shift+3 to check. what so ever the different flag should not be used outside HDR API with HDR API that should be bt2020. unlike nvidia madVR can't tell the driver what is is supposed to output that part doesn't work back when madshi was implementing it for nvidia. |

I created my LUT when the output was set to 8 bit when i don't have the level issue, and i think its created correctly as when i do a full measurement in HCFR everything is under a deltaE of 1.
I wondering if the driver and/or Windows is doing something behind MadVR's back when in 10 bit mode. There shouldn't be any reason to output the BT2020 flag but something is setting it. I wonder if this same path is breaking the level output as well. Either way for now i'm just going to stay with 8 bit output, its not worth the headache for 10bit . |
