I had to stop playback and restart. Very inconvenient.

Do such things still happen on Windows 10?
Yes, I sometimes have the same problem, but it only happens if you leave the PC long enough so that Windows turns off the display. So one workaround would be to increase that time or disable the function completely.

The latest version is slightly over one month old and development has stalled?

No idea if this is even correct.
2016 LG Oled owner here.

Do you have the color gamut on your TV set to something other than normal? With normal you should get correct colors in madVR with calibration disabled.

If you set the color gamut to wide than madVR set to DCI-P3 looks correct, not sure if it's 100% though.

that was my first thought but I've got it set to normal even on my HDR preset.

I didnt actually notice this until I watched star wars the phantom menace recently, the scene where the princess is called an Angel by Anakin when they meet for the firs time, their faces are really red.

i'll try get some pictures.

note, it cant be my TV as when I switch renderer to something else its fine, its just MADVR.

Even allowing for my crappy mobile photos you can see a clear difference, top is standard EVR renderer in MPC-HC, middle is MADVR+ MPC-HC with calibration disabled, bottom is with MADVR calibration enabled. In situe the top one look most accurate, followed by the bottom with the middle with blown out reds.

Again, i'm only seeing this in MADVR, all other renderes are fine so its not my TV or GFX card. I've tried a full wipe and reinstall of MADVR, i've had this issue for the last few versions.

I just tried EVR and madVR side by side and the colors look identical so there must be something wrong or buggy with your setup. Did you check the "color and gamma" tab in madVR? Maybe you messed around with it and then forgot about it?

How did you show them side by side, when I come out of full screen any processing MADVR is doing is removed so they do look iddentical, has to be in full screen.

Also, is there a performance hit when you use calibrated settings?


EDIT, this isnt quite right, it does look correct out of full screen and if I change to BT2020 I can see the change, the colors are becoming overblown only when i'm in full screen, whats going on there then???

There is a small performance hit when using a 3DLUT but "calibration disabled" is actually the same as the default already calibrated setting (BT.709, pure power 2.2); there is no change in performance between already calibrated and calibration disabled.

There should be no difference between fullscreen and windowed.

ok found the problem - this happens only in full screen and when i have DIRECT3D 11 for presentation enabled in rendering, which I need enabled for HDR playback, ideas anyone?

I don't think that is true. In calibration disabled mode I don't think madVR remaps gamuts.

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'm pretty sure it was changed to BT 709 for no calibration settings.

this should be very easy to test.
i have no bt 2020 file on the Pc i'm currently at.

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

closest i cant get to EVR is using display calibrated to BT2020 using BT709 transfer function 1.08, no idea if this is correct but it looks pretty good to my ageing peepers

Hmmm...I'm assuming you're not using passthrough...if it's overblowing, then your TV is set to some native (full gamut) mode or P3 mode (if you choose DCI P3 in MadVR and it looks the best, then this would prove that the TV is not in Rec709 but in P3 or native mode)...madvr is unaware of the color gamut of your TV, with no conversion it just send color as is, or converted to rec709 if it's HDR video (I assume the latter from my own testing)...

Hi, PASSTHRU? this is SDR material i'm talking about, havent even looked at HDR yet, that may also be problematic.

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?

Yeah that does work - when you turn calibration off / on you have to reload the image though.

@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...
