Basically, I don't think anyone should really be using calibration disabled, if you don't have a meter to calibrate, then just set it to "display already calibrated" and typically BT.709, unless you know otherwise from your TVs specs.

I think it is BT 709 as my reds are overblown using DRECT3d11 in both calibrated off and calibrated to BT709. If I use DCI-P3 it is better but its still quite red compared to EVR rendering, if I use BT2020 its a bit far the other way but look more natural in a way.
Can anyone tell me what this should be set to and why having DIRECT3D11 ticked is causing my colours to overblow in red? I have a LG OLED EF9500 HDR TV Last edited by mclingo; 9th March 2018 at 00:40. |

After some more fiddling I updated which settings a couple of posts up, I found the most accurate picture was BT2020 using BT709 transfer function 1.08. I still think its odd that this problem goes away when I deslect DIRECT3D 11 in MADVR, I feel this is where the problem lays,nobody has explained that yet, could be other people have this problem but just havbent noticed yet as its not that obvious in most movies, this particular scene is very noticeable. If this were an issue with my TV then EVR would also look bad, there must be something wrong with MADVR's calibration off settings, whatever they are they should surely mirror what EVR renderer is doing when off, surely? Could do with some feedback from @MADSHI on this really |

actually, isnt is possible to do this from a screen dump, I cant test this from work, you should be able to open with and choose MPC, it will load this as one frame and process it full screen?
https://www.dropbox.com/s/mvq9zy92uh...33%5D.jpg?dl=0 Yeah that does work - when you turn calibration off / on you have to reload the image though. Last edited by mclingo; 9th March 2018 at 15:22. |

@mclingo: sorry, somehow I missed that conversation had progressed quite a bit since the quote...still, I find it odd that, in my case any changes in transfer function/gamma section does nothing for SDR video but indeed does something for HDR, other than that I find no difference regarding color between DX11 and DX9 modes...

link to clip, note however I can see the difference on any movie, its just more obvious in skin tones on this clip. Last edited by mclingo; 9th March 2018 at 16:22. |

That's strange, MediaInfo says it's flagged BT.709

so what? is it a container flag or a stream flag?
madVR doesn't get the needed information so most likely not a stream flag. @chuchicoupe if you are using an nvidia card check the power settings in the NV control panel make sure it is >not< optimal. |

The most likely reason for such color differences are bad configuration on the GPU control panel though, and not in madVR.

yes it falls back to bt 709 for this resolution but is this file really bt 709 and not smpte C?
in term of faces colors i don't think bt 709 is correct. with a proper flag there would be nothing to argue about (which would be BT 709 nearly for sure...). doesn't fix the issue anyway d3d9 or d3d11 are the same for me so this is something todo with the screen settings or GPU driver. |

Thanks for the info anyway. (I might take a peek at RS4 anyway, well isolated form everything else) Last edited by mzso; 9th March 2018 at 20:55. |

well thats interesting, it does the same thing with my 40" samsung MU7000 plugged so that rules out my LG OLED TV, could be my receiver though I guess, I'll bypass that next.
reciever also bypassed same result so it has to be my settings of a problem with the GPU, everyone else is testing this with NVIDIA cards? Anyone got a similar setup to mine? AMD RX 550 18.2.2 LG OLED 2015 4K Win 10 creators up to date Last edited by mclingo; 9th March 2018 at 21:39. |
