Try HDR passthrough as well before you use the newer HDR options (which you have switched off in Trade for Performance mostly) and work from there, but do what the others have said first. Last edited by madjock; 20th January 2019 at 18:09. |

your lav filter setting are showing software decoding and you have a select a hardware decoder so this looks like an incompatible file format. |

Checked now. It's HEVC, mkw and HDR file. You can download it there....

Any idea to activate it? Any option under nvidia control panel? |

Showing proper aspect ratio/zoom on Ultrawide Monitor for content that changes Aspect
Hey all,
So hopefully this is a simple question to answer, but I've been fighting this for some time and I don't seem to be any closer to solving it. I have a 21:9 Ultrawide monitor. It works great watching films that are shot in CinemaScope. Some films (mostly Nolan films) will change aspect ratio from 16:9 (for IMAX shots, for example) and then for normal shots will be 21:9. I'm trying to figure out a way to show all content with as few bars as possible. This would mean: Zooming 21:9 shots to crop the letterboxes NOT Zooming the 16:9 footage and showing pillarboxes. I can't seem to get MadVR to do this. I've tried dozens of combinations of settings and the best I can do is have it either zoomed to 21:9 all the time (losing picture during 16:9 shots) or just showing pillarboxes ALL the time and then also showing letterboxes during 21:9 shots. Here are the settings I have: *Disable scaling if image size changes... Tried all different settings, currently on 3 lines or less * Move Subtitles into active area * Automatically Detect hard coded black bars (yes) * if black bars change quickly ... don't switch more than every 5 seconds (tried disabling this too). * Notify ... immediately after every change * Zoom small black bars away * crop black bars With these settings, nothing seems to be happening at all. Dunkirk will just play in 16:9 with pillar boxes and letterboxes in 21:9 scenes. If I enable: * If there are big black bars... zoom the bars away completely Then I get the entire movie at 21:9 with no boxes anywhere, because it's zooming them away... but then I'm losing a chunk of the frame. Basically - MadVR either lets me have no boxes (pillar or letter) or just leaves it alone. This would work if I had a 16:9 monitor and I was playing 16:9 content that switched to 21:9 because the bigger frame is my native aspect ratio, but when the native ratio is wider than the film ratio, it seems like this causes issues. For now, I have to flip in and out of zoom levels with keyboard shortcuts, but this sucks. Am I screwed? Is there no way to fix this? |

This says that native dithering is possible with NVidia Linux drivers and Windows Quadro drivers and now regular GeForce cards, but I can't get it to work or figure out how to test it https://steamcommunity.com/groups/Sp...8172123104780/
Is this how it is supposed to look like in the registry https://drive.google.com/file/d/1uin...w?usp=drivesdk ?

nvidia is using dithering in like forever and it's very easy to test.
the examples are more about the the type of dithering in an ideal situation we don't want the image from madVR to be dithered by the driver. so the only useful situation i can see here is the 6 bit dithering which madVR can already do... |

not selecting a GPU results in native mode which is supposed to be faster but you can't use all blackbar detection features and other stuff like deinterlancing.
selecting a GPU is better for compatibility but DXVA copyback does the same and DXVA copyback was faster than D3D11 copyback if i remember correctly but not that it matters. |

but the non-selection of the GPU in the lav is for 4k hdr files or for everything? me with 1080p material I feel very comfortable with DVXA copyback and I have no problems, reading the message of warner I came the doubt

Perhaps this was not the most appropriate place to post that info, but I generally wanted to know how to truly enable NVidia dithering for desktop. That way Netflix content gets dithered... I doubt we will ever see madVR support for Microsoft Store Netflix App. Therefore driver-forced dithering is the only way to enable it for Netflix...

you missing the point there is nothing to dither after your netflix app/browser.
and games send presentation frame to the driver if they are not before that then there simply isn't anything to dither which wouldn't be dithered anyway. it is very simple to test if nvidia is dithering. you take a gray scale load it in madVR with 10 presentation and you force your GPU driver to send 8 bit RGB. if you don't see 256 steps the driver is clearly dithering.

God Damn It, just noticed AMD Dxva 4KHDR causes banding.. That's it, Final Straw, I'm selling my RX580..
Not going to sit around waiting for fixes for 3 years.. Sad, because I got a great deal on this card, Overclocks like a champ and runs super cool. Gonna have to buy another 1060, sigh... all these ebay miner 1060s look so ragged/shi77y ..
