The edid says my TV accepts pixel clocks up to 600Mhz but no single one madvr calculates seems to be accepted. EDIT: @Warner306 Do you use FullHD or 4k resolutions? Does it matter at all? Last edited by waldnebel; 5th July 2018 at 08:54. |

@MADSHI - AMD have been in contact with me regarding the two main issues we have with MADVR - 1. HDR toggle no longer working since 18.3.4 and blown out reds with SDR material @23,976 - since 16.8.1.
Is there anything you can tell me that you've tried or anything I can add to my replies, they are asking what diagnosis has been dont with MADVR itself being that both of these issues only seem to affect MADVR right now. |

"too many issues with NVIDIA right now, AMD have their own issues too but I have workarounds for all of them" https://forum.doom9.org/showpost.php...ostcount=51658 Seriously though, maybe your spare nVidia with a custom resolution is a better answer for you at this time.

If this persists, I would guess something in the Windows Update is causing problems, or something in your configuration is different, but I couldn't guess what might have changed. I would try to avoid having madVR put any custom resolutions into the control panel that can't be edited or overwritten. Trying an 8-bit resolution might also help. Don't know.

@Warner306 He probably used the checkbox "clean installation" during install.
@waldnebel use DDU in safe mode to remove all traces of nvidia files. Then install the latest driver. Before creating a custom res, try the default refresh rate first. Try playing a video for AT LEAST 15 minutes. The latest few nvidia drivers have improved something. |

I know this has come up in the past but I've run into it again: Weeding out some of my collection I came across Children of Dune (2003) encoded in 720p @50Hz. My intention was to see how CGI on this looks with madVR. Instead I was met with judder. Knowing I have a 2160p25 display mode madVR may switch to added, I checked NCP current resolution. It was 60Hz and my panel was reporting the same. 50 is a multiple of 25. nVidia and my panel should have switched but it didn't. My display is capable of 25Hz and 50Hz. So, I added 2160p50 to the list of resolutions madVR can switch to and everything then matched refresh rate and switched to 2160p @50Hz and the judder disappeared.
Fwiw, using match refresh rates with official KODI VideoPlayer also does not switch rates for this particular title and there is no where to tell it to. Thank you madVR. Other rates do switch. I'm pondering if displays that only have rates of 23, 24, 25, and 60Hz take advantage of multiplying while displays that handle all refresh rates need to be specifically told which one even if it is a multiple. My current list madVR may switch to now looks like this in case anyone notices the same and I don't think there are any side affects: 2160p23, 2160p24, 2160p25, 2160p30, 2160p48, 2160p50, 2160p59, 2160p60

Nothing switchs to a 25 Hz mode when playing 50 Hz content. You would have to drop half the frames.

Gonna make the jump to 2160p and my 7850 won't hold a candle to it, FWIR here Polaris isn't too happy about NGU so how about a 80 bucks refurb R9 380 with 6 months warranty?
I only care about mVR so benchmarks appear to be irrelevant for mVR purposes? 7850 is da bomb with 13.12 drivers @1080p, I want the same but for 2160p and not for 200 bucks either if any possible Any advice fellas? |

dont think that card is a true 4k card, you'll only get a sub 60hz desktop at 4k, fine if you're not using your HTPC for anything else but I wonder if you'll have other issues with it not being a full 4k card with the increased HDMI bandwidth, you'll need to look into that.
you could pickup an RX 460 for about 60, you'll get NGU sharp low around 30ms rendering, that What I was getting prior. EDIT pretty sure its HDMI 1.4 spec, unless there was a late HDMI 2.0 version? Last edited by mclingo; 5th July 2018 at 21:40. |

I suppose you have enough GPU power for very high for chroma but even using low for chroma upscaling you cannot use NGU very high for image upscaling? Also the hardware decoders are not as good, 4K 10 bit HEVC takes a lot of CPU if you have to use software decoding.

It’s a card that could make you take up video games. With games, it sometimes outperforms the GTX 1060. It’s not surprising that it has enough power to handle madVR.

Perhaps with crappy subsampling and at 23,967Hz. Considering a large portion of this thread is about how practically none of commercially available screens are able to properly display >8bit colors and reduced picture quality because of subsampling I would count this as irrelevant, but that is just my opinion. Oh and I almost forgot the potential for flickering when the camera is panning if the display isn't able to properly display 23,976Hz since higher refresh rate isn't possible at this settings.
