EDIT I have more info. The movies that are being upscaled to 2160 (but displaying correctly on the TV) are being received by the TV as BT2020. The movies that are switching to 1080 and getting zoomed by Windows scaling are not showwing BT2020. Does this clue anyone in? EDIT2: OK I set MadVR to 8 bit and although it now does not say BT2020 on the movies that upscale it continues to upscale them so not the cause that I can see.

You go in---->devices---->your monitor or TV----->display modes You do that only if you wanna use 24p Example : 3840x2160p23, 3840x2160p25, |

OK I managed to figure out one part of the scaling issue but it's still not right. When it switches to 1080p (for those movies it allows it to) the 1080 scaling was at set above 100% I moved it back to 100% during playback and applied it. Now instead of zooming 1080 when switching from 2160 it is shifted to the right of the TV display by one half. The left half is black.
For now I will have to leave the display at 1080 in Windows settings as it is mostly HD stuff I play and only switch to 2160 when I want to play UHD/4K videos. But this is really annoying. I am not sure if it's a bug in Windows display otions, driver bug(s), a MadVR issue, The TV scaling or a combination of all of them. Last edited by oddball; 26th February 2017 at 12:57. |

I had a thing some time ago and TV with AMD was reporting the wrong resolution of 4096x2160 instead of 3840x2160.Make sure that this isn't happening to you.Whatever happens set video card to 3840x2160 and then when playing the files you want check what resolution TV reports.
Skip this video to 12:01 and go fullscreen to check what happens https://www.youtube.com/watch?v=HKRcpCQJW8M (there is a download link also if you want to test with Madvr.) Quote:

OK this is just damn weird and I think it's either a Windows 10 bug or a driver bug.
If I set the TV to be the 'center' display everything works. It switches to the correct resolution from MadVR and scaling does not move the video or zoom it in any way shape or form. But here's the rub. My TV is off to the right of me and my secondary monitor is off to the left. So it's the wrong way around when mousing from left to right (I have to traverse the TV display as screen 2 to get to screen 3 on my left). The other snag is when I finish playing a video and exit the resolution stays at the last resolution played. So the TV will stay at 1080 if the last movie played was 1080 and visa versa for 2160. For some reason it's not switching back to what the default resolution was. |

You can use win key+p to switch between displays.Choose the correct side in amd radeon settings.
Set resolution to 3840x2160 in video card/windows and make sure restore original display mode... is ticked in Madvrs display modes. |

OK a hard reset fixed the switching issues. Scaling is still screwed but I can just leave the TV at 1080 since I am not using it as a PC monitor anyhow. Windows scaling is a bit busted for multiple displays if switching resolutions on-the-fly. Just a quick note. When I say Windows scaling I mean text DPI (the slider).

This Wednesday I am finally getting a projector with lens memory function (jvc x35) and I am now making different profiles according to aspect ratios. However I wonder whether madvr after playback automatically changes the lens memory back to the whatever it was before playback.
Example: I use memory 1 for viewing the windows desktop in 16:9. A cinemascope movie is started and madvr activates lens memory 2. After playback, will madvr be stuck on memory 2, or will it change back to memory 1? Yes I know, I could wait until Wednesday, but I'm curious. |

Unless loading custom shader presets such as those at https://github.com/libretro/slang-shaders and https://github.com/libretro/common-shaders is added, I may have to stick with madVR v0.93.1 indefinitely. Actually, that would be an awesome idea. There are tons of awesome shader presets there that would be nice to use in a media player. |

I am guessing "luma" here is "image upscaling". You're saying "keyboard shortcuts" contains an "image upscaling algorithm - set to 'Nearest Neighbor'" entry, even after the version that removed the radio button selection for it from the GUI? If so, thanks for the info. I'll check that out when I have a reason to update.
Also, why do you seem so embarrassed about using nearest neighbor that you have to write "which is not often and mostly for testing purposes"? Nearest neighbor is the only truly sharp algorithm provided by madVR for low-res pixel art video (256×224, for example). There are better shader presets for non-integer upscaling like "anti-aliased nearest neighbor", "pixellate", and "sharp bilinear", but madVR has never provided any of those so nearest neighbor will have to do. There's no shame in wanting to use nearest neighbor for some video content, to be able to inspect the pixels clearly. Nearest neighbor is perfect for integer upscaling, too. I don't see an option in madVR for that though. |

Yes the "luma upscaling" wording has been changed to "image upscaling" now but that is what I mean. And I have made shortcuts for those in the latest madVR version so yes it still works (even though it has been removed from other places in the GUI).
Mind you it will reset to your settings from the "scaling algorithm" section when you close madVR. Not a problem for me but if you need to have it enabled by default it's not an ideal solution. And I'm not "ashamed" of using it It's simply not very often that I want to. I mean, I mostly use madVR to watch blu-rays upscaled to 1440p so it wouldn't really do much good for that purpose Last edited by kalston; 27th February 2017 at 03:47. |

Is there any reason why with the following in madvr's monitors display properties, it will select 2160p30 for 25hz material?
2160p23, 2160p24, 2160p25, 2160p29, 2160p30 If I remove 2160p30 then it will choose 2060p29 fullscreen, only after I remove 2160p29 also will it correctly set the refresh rate to 2160p25. |
