Personally I can only see a difference between Ordered and Error Diffusion at up to 6-bit at normal vewing distances on film content. When using 8-bit I don't see the difference unless I have my nose on the screen. I didn't test anime yet. Colored Noise and Change Dither for Every Frame are just personal preferences, I personally can't stand them especially Colored Noise.

Windows 10 works perfectly for me with multiple displays running different refresh rates so I am not sure what the relative benefit of 8.1 would be, it is probably very minor or use case specific. Edit: Both are much improved over Windows 7. I agree! Especially about colored noise!

On top of that, Windows 10 is playing a bit of a catch-up game with HDR. Microsoft is changing how HDR works every Windows 10 release, and the video drivers are only adapting to that slowly, leading to bugs (both in Windows and the drivers) Windows 10 has some advantages, like the 10-bit fullscreen windowed mode, which is kinda neat, but it also has its share of issues still. Hopefully that changes over time, though.

Dithering mostly depends on your screen, there is no universal answer - different panels make dithering noise look different. There is only one choice, to try and judge with your eyes. Theoretically Error-Diffusion is better, in practice however most people will never be able to tell any difference, and it costs quite a bit of performance.

When playing 4K 24fps HDR content I get continuously dropped frames with jerky playback, however average rendering stats is below 30ms. My display is an older 4K LG TV without HDR function, so I let madvr convert HDR to SDR.
I didn't have such problems with other content. Any help would be appreciated. |

I'm trying to play a 2880x2880 file on a 4k LG OLED, but I'm getting a black screen instead when going fullscreen on the TV. Sound plays, no image though, but if I move the mouse over the lower part of the screen, the MPC-BE playback bar appears fine.
The TV is connected via HDMI to the PC. The same file plays fine on my PC monitor when going full-screen on 1920x1200. I'm using: MPC-BE 1.5.1 (b2755) LAV 0.70.2 madVR 0.91.11 All of the above are x64. Any idea what the problem could be? Could it be madVR? |

Currently the following hardware, software are in use: Kodi 17.3 Dsplayer version Windows 10 64 bit OS Nvidia Geforce GTX 1060 6GB LAV 0.69.0.81 madVR 0.91.10 i3-6100@3.7GHz During play my CPU is on 100% utilization, however I am using DXVA2 for hardware decoding. Sorry for asking, but regarding OSD, do you mean a screen shot of rendering stats during play? |

I know, but I do not understand how this could happen using such a hardware and software configuration. In case of upscaling HD to UHD, the CPU average utilization is ~20% with high quality settings used. In case of no any doubling (when source is 4K, output is 4K) the CPU seems to be "exploding"...I assume madvr/LAV filters/Nvidia drivers has some problem with high bit-depth HEVC streams to decode/render them correctly.

No need to quote when replying directly after my post. UHD is generally quite demanding and you only have a dual core CPU which is insufficient for the tasks you require of it, you need to upgrade to a recent quad core at least.

Could be more demanding than doubling a HD source using the same fps, codec, bit-depth?
P.S. I have never been noted not to quote when replying directly after a post (deleted the quotes). Furthermore, I do not really think it has much of interest (but surely can adapt to it if required). Anyway, thank you very much for the help. Last edited by mparade; 3rd September 2017 at 11:20. |

@mparade: 1. check in LAV Video properties the 'active decoder' during playback, to make sure that DXVA is indeed used. GeForce 1060 can't play VP9 10-bit (Profile 2), for instance, so if your HDR file is coming straight from YouTube it won't be decoded in hardware. 2. Check the queues in the OSD. When testing, I encountered situations where the rendering times were confortably below the frame time but either the decode or the present queues were not filling up and frames were being dropped. 3. Do you use Copy-Back? Try Native just for a test. On my system I can't watch 4K using Copy-Back. Your system is very recent but test it anyway, you never know. Note: if you update to latest madVR version and LAV nightly, you can use DX11VA Native, which doesn't have the quality issues of DXVA2N.

I am going to update LAV filters and madVR now. Give you a feedback shortly. Only SMplayer could play correctly these 12-bit HEVC HDR files. According to the specs of my GTX 1060 and the latest Nvidia drivers this card does support 12-bit HEVC decoding: https://forums.geforce.com/default/t...-a-k-a-h-265-/
