You really need a minimum of 1000 nits otherwise you need to make compromises somewhere. With regard to applying the HDR LUT it won't auto apply at present and you will need to use the one in the DisplayCal folder |

Since following that little nugget of advice I'm not getting all that red crap in my highlights like I was before |

If you don’t care about the extra luminance in the highlights I suppose you could use 10k but then it is much darker than passthrough is, at least on my OLED with it peak brightness just below 700 nits after calibration. My display is already struggling with brightness for HDR, a 3DLUT that dims it more is not a good option. Harry Potter, for example, is very dark with a 3DLUT generated with peak nits set to 10K but looks normal with passthrough. It is not a really small change, it is quite significant and much more noticeable than improved hue, etc. Right now a 3DLUT completely ignores the video’s metadata doesn’t it? There is a reason HDR is moving to dynamic metadata and tone mapping that changes for each frame, not just every video, and a 3DLUT that does 1 tone map for everything cannot be as good or there is no point in even having metadata for HDR in the first place.

The next madVR build is supposed to add a profile rule for the peak luminance of the video. This should make it possible to use multiple HDR 3DLUTs for multiple HDR standards. Not perfect, but an improvement.

No. Don't listen to foozoor, he is just constantly trolling.

At the moment the best way to use a 3D LUT with MadVR for HDR content is to use a BT2020 SDR calibration (with a power gamma of 2.4) and use the pixel shader HDR to SDR conversion. If you set your display to its peak brightness (or whatever you're comfortable with with HDR) you're still watching HDR (it's just that the conversion is done in the source instead of the display). You can then create different profiles for various values for peak brightness, according to content. And you only need one SDR BT2020 3D LUT to get best accuracy all the time. Madshi didn't have the time in the last release to include the peak brightness variable that will allow us to use profiles to select automatically the best profile, but you can still switch manually with a key combo (or iRule). I'm still using passthrough because I have implemented in the Vertex with HD Fury a way to automatically select the best custom gamma curve for my JVC according to the content, but as soon as MadVR catches up I'll most likely use pixel shader (provided we get 10bits back as there is no banding in pixel shader, unlike passthrough), as having a 3D LUT significantly improves results, even on my autocal'ed JVC. Ideally the next step will for MadVr to dynamically adjust the curve to the content, so we won't need profiles anymore, but we're not there yet.

I have following setup
- HTPC (i3, 8gb RAM, Nvidia 1050) - Yamaha A3070 AVR - JVC X790r Projector I recently started using madVR with Kodi and MPC-HC and having a lot of issue playing 4K mkvs with HDR. When I play a file using MPC-HC (with madVR set to pass through HDR and no other settings changed), my projector automatically switches to HDR mode indicating that HDR signal is being received but the whole pictures has dark pink/purple tint on it. As soon as I end playback, everything goes back to normal. If I select Enhanced Video Renderer (Custom Presenter) in MPC-HC, video plays correctly but HDR tag is not passed so no auto switching is done by projector. HDR is turned off in Windows settings (and I am unable to turn it on because when I try to do that, everything goes black and by the time pictures resumes the prompt to confirm selection is gone) I have also played with setting in madVR to convert HDR to SDR but the results have been less than ideal with more prominent noise and depending on the settings colors ranging for overly saturated to very pale. I have already tried different HDMI cable and doing a clean install of Nvidia drivers but not much luck. Separately, I'm having another issue which may or may not be related and that is I cannot set the resolution in Window or Nvidia control panel to 1080p/60. For some reason it keeps getting back to 4K/24. When I try to set the display setting to 1080p/60 the screen goes black and when it comes back I usually have a second or two to press a button to confirm changes otherwise it reverts back to 4k/24 setting. If in case I successfully change the settings it works for sometime and then randomly changes back to 4k/24. I have checked on the AVR and video is set to "Pass through" on the projector it shows that it is receiving "4K signal". So there is something in the HTPC which keeps switching the resolution/frame rate. For the most part I can live with that setting but some of the programs (like Nvidia Control panel) do not scale even when scaling is set to 300% so they are impossible to use on 120" screen.

custom mode problem
Hi everyone!
Please someone could help me. I have tv Samsung UE55J6200 which connected to PC by hdmi cabel. I tried to make right settings for watching movies slightly on 23,976 ghz. But i have problem with custom mode. My adapter is GTX 770. I heard that NVIDIA has problem with right 24 hz. So in MADvr there are 23 hz mode is active, when on NVIDIA in custom mode is 24hz. Than I tried to optimize settings, watch film for 30-40 minutes than i go to settings and see this: I picked mode without frame drops and repeats, push Test mode and screen of my TV becomes black. I suppose GPU are not supported right mode. But why? How can i solve that problem? Someone has it? So how is right to calibrate this? |

Not this time. Madshi did say he was getting external help to deal with 3dlut stuff I think it was. Speculation is gonna happen in a forum.

On another note I was playing with FSE to test out 10bit color and noticed that the composition rate was listed as 60hz even though I had the screen at 24hz. Last edited by ryrynz; 25th May 2018 at 00:15. |

I know what madshi said, he is still using that information to troll.

This is by far the most undesirable aspect of display calibration, even if you manage to understand all of the different aspects of display calibration (there is no button that says, "push here stupid"), you're still at the mercy of people who are supposed to know better, but still **** it up.

I had no joy with the custom side of MadVR, if I tried anything else apart from the custom res that I set up in Nvidia that MadVR saw, then I just had a fuzzy screen mostly.
Best I could get it to was 1 Frame Repeat every 38 minutes with Custom res and Nvidia, better if I took some settings down, so just learnt to let that go. Had to roll back to an earlier driver with Nvidia to get the custom res to stick as have many. |
