Re: DCIP3 vs BT.2020 vs BT.709 vs Disable calibration control for HDR and SDR (all resolutions). I don't have an "enhanced" setting on my display? I don't have a "wide" setting? If you mean FULL aka Normal aka 0-255, yes I have that and I use 0-255 in all my hardware and all my software.
I was not limiting my questions to HDR only. I was pointing out that a correct value of BT.2020 for HDR sources is not a correct value for SDR sources in my display. Using that, SDR looks under saturated. When viewing SDR, if I change the value to BT.709, DCIP3, or disabled, it looks much better. I am using "passthrough HDR content to the display" and am allowing the panel to convert and process HDR. So, these settings in madVR for HDR don't apply. What will apply is SDR calibration settings in madVR. Again, what looks the best to me are BT.709, DCIP3 or disable. I can't see a difference between any of these. BT.2020 on the other hand, looks under saturated. It also isn't reported in the OSD for SDR. BT.709 is. In the past I simply chose DCIP3 and it looked good for HDR and SDR. Now you're telling me HDR is best with BT.2020 and not to use DCIP3 for those. I can't use BT.2020 for SDR so I guess I have to separate HDR from SDR and apply accordingly. All of my HDR titles are UHD HDR 2160p and they are all BT.2020 and they all report they mastered in DCIP3. All of my SDR are 1080p, 720p, 540p (SD) and they are all BT.709 (best guess). I created a profile for 2160p through SD resolutions. 2160p (all HDR) calibration I set to BT.2020. (not that it matters since everything is passing through so why create separate profiles other than you say to use BT.2020 even though I'm passing through) All the others I set to DCIP3. I can also set all these others to BT.709 or disabled. Which would be more correct, for these others, DCIP3, BT.709 or disabled? I assume BT.709 since that is the 'best guess' reported but you say DCIP3 is better so I'm using that. Or, am I completely doing things wrong here and if so how would you do it if you were me? Describing various branched off scenarios is not me. I'm not using HDR to SDR conversions. I don't use 3D LUTs. I'm in standard mode and asking about SDR, not HDR. I don't have meters and such to measure and track gamut widths. I'm asking specifically for my setup if you were me. If you need further details, I'll be happy to oblige.

My display is LG E6 so im sure it support 30hz though, i thought you mean to change refresh rate in nvidia control panel so there i can change but only when not playing any movie, once movie is on refresh automatically change to 59hz in nvidia panel. I will try to check on windows display settings, and see there. The part about image i was just curious why i cant see any numbers on madshi chroma pattern test when i have set full RGB with black levels on high in TV settings, once i set black levels to low i can see both number 4:2:2 and 4:4:4... but then black is way to bright, i though maybe this is a bug or something. |

It sounds like your TV's processing is 4:2:0 when you set black levels to high. 4:2:0 should be the only time you do not see either number in the chroma test pattern (just in case, make sure you are viewing it 1:1).

But doing this makes the picture a little bit strange, it is a bit blurrier because the resolution is no longer a native one. Also even with 1920x1079 madVR cannot switch to this mode because when trying to set madVR to 1079p24 when it goes full screen it will mark this setup as invalid and does not let you apply this mode. So it just defaults to 1080p24 with non of the settings applied even if you keep the 1920x1079 mode set up in nvidia control panel. So it looks like nvidia did something that locks the native 1920x1080 resolution so it is no longer possible to tweak unless you also change to non native / non standard resolution.

If u mean by 1:1 fullscreen then yeah i always look at the pattern in fullscreen. It's quite funny cause this is the only mode i can't see any number on it. When i set Ycbcr either 4:2:2 or 4:4:4 there is always visible one or both numbers depending on mode. So my question is, should i worry about it ? shall i leave it like this ? or i should change something ? what i should see when i set to full RGB ? I need to check if i have same issue on PC mode input on TV when set to Full RGB. Thanks buddy for all your effort trying to explain all this to me, appreciate it |

You need a GPU with HDMI 2.0 and an HEVC decoder. Does your GPU qualify with these specifications? This would not explain your issue with refresh rates, however.

For SDR calibration, if your TV doesn't have a gamut setting, it can be assumed it is BT.709, as this is the correct calibration for SDR content. I could be wrong, but that is most likely. Check your display on Ratings.com for more detailed discussion.

Ok will do, once i get to home. Just to make it clear in my head, so my refresh rate should change automatically to a movie fps? or what determine which refresh rate should be at the time? cause im kinda lost here... At what shall i look at madvr osd info to see if it's correct or no ? cheers |

Hello.
1 HTPC using madVR / Lav filters and possibility to run movies either with mpc-be or potplayer (with exactly the same settings) With Potplayer, Clock deviation is always at 0.00000% (after few seconds) ==> Great ! With MPC-BE , clock deviation is always not null et does not converge to 0.00000% This make the consistency between the counter "1 frame drop/repeat every" and the "display" information wrong with MPC-BE. 1. Have you some information on the root cause ? 2. In case of display frequency optimization with an HTPC using MPC-BE, what is the counter that i need to follow ? (The value of drop/repeat per time or the value of the display) i think , base on the comparative test i have done that it is the "display value" but need confirmation because in this case, even in case of perfect settings of display resolution frequency at 23.97602, the value in Drop/repeat is far away from "no drop/repeat frames expected") Last edited by Polopretress; 28th March 2018 at 20:57. |

Ok. The "wide" color gamut on my Samsung is called Color Space, specifically Native. So no, I'm not limited to BT.709. The Native setting brings it to BT.2020. This is how I've always had my settings. It covers 91.7% of DCI-P3 with my 'Native' color setting aka 'wide'. Given I do have a gamut setting and I am not limited to BT.709, which of the settings I inquired is best?

Your's is similar to my display, for SDR using "this display is already calibrated" set madVR to DCI-P3.

Yes, back to original. Thank you for the confirmation.

It actually might be better to use use "normal" gamut but then set madVR to BT.709. There is no reason to disable madVR's calibration if you know your display's gamut, it will only convert something if it not the correct gamut. This is important for SD material, which is often PAL or SMPTE-C, so madVR converts them to BT.709.
Edit: Which is better depends entirely on your display. My TV's calibration is better if I use "wide" and compare it to DCI-P3. If I use "enhanced" and compare it to BT.709 it is pretty over saturated. However, if my "enhanced" (your "normal") option was closer to BT.709 it might be better to use that and have madVR set to BT.709.

Ok so this trick did the job now i have in madvr osd : display 59.9hz clock deviation -0.00000% when i added 2160p24, 2160p25 then display it's showing actual refresh 23.976hz clock deviation 0.0000% but when switching off mpc-hc refresh rate doesnt change in windows though, it stays in 23hz Now i did try to check chroma pattern test image over PC label on tv and this is what i can see, please see attachment. So what i should leave and how, cause im really confused ??? 1. Shall i leave those two strips too in madvr 2160p24 and 2160p25 but then i need to manually change refresh rate for my desktop. 2. Shall i leave PC input mode, cause then i can clearly see both numbers in chroma pattern image ?? 4:4:4 is bold 3. Or i can just leave hdmi input on tv and not bother about chroma image pattern ?

quite funny cause those were ticked switch display when player start and restore when player shut but didn't kick in. Once i changed for second apply and then back to first option, now it's kicking in properly |
