And nvidia colntrol panel doesn't save anything anyway. The list is empty after you switch back to 60hz. So there is nothing to delete. Edit: This is the error that I get when I try to tweak the settings to get perfect 1080P@23.976hz Doing this worked fine with previous driver. nVidia changed something and broke it. And this is what happens after making a new custom resolution with nVidia Control Panel. Nothing happens, the list is just empty after applying the changes.

The Nvidia CP never worked for me, I tried to use it to create 1080p23FP (3D) custom res and it doesn't save anything.
MadVR custom res (At least the one I made for 4K) sticks though with 391.01.

But it always worked fine for 2D @1080P This HDTV is not 4K so I can't test 4K. |

Sorry for asking but it's impossible to follow this thread- to big
Does current madVR pass full display mastering info to HDMI on GTX 1080? Is there a way to "see it", other than some HDMI analyser? Can anyone confirm that this actually is used (for example I can flag P3 gamut instead of Rec.2020) by HDR TVs eg. Samsung KS8000? |

What the display does with this information is up to each display. If you want to inject specific metadata you’ll have to use another device, as far as I know MadVR doesn’t allow custom injection.

Thank you.
Yes, I'm mainly interested in Pass Through mode. So if file has some meaningful metadata then it's passed. If metadata is missing or "bad" then it's replaced with some default one (do we know what it's?). In the same time there is no way to specify "custom" metadata which would overwrite original one in the file. Yes, there are tools for this, like HDFury box or AJA converter: Do you know if HDR TVs really use this metadata? All sample files made for TV manufactures seems to have them. In the same time when you play file inside TV (through its own player) mastering info seems to be fully ignored, at least on Samsung KS8000. I don't know if this is different in case of signal coming over HDMI. Do you also know if Pass Through mode is 100% "lossless" except format conversion (e.g. YUV420 10bit to YUV422 10bit). I'm interested in mode which will guarantee me that signal is really passed without any unnecessary "touches". I would also rather prefer to stay in YUV and let TV convert this internally.

Hmmm... this is interesting and bit "crap", specially when many modes for HDMI are only possible as YUV.
I assume RGB<->YUV conversions are accurate. I'm sure I've read that LAV passes all HDR metadata from x265 encoded and flagged streams, so we should have precise path (except those YUV<->RGB conversions). Last edited by kolak; 1st March 2018 at 21:29. |

The way displays handle HDR metadata is fairly OT so I'd rather not engage in this discussion here.

Useful info.
Have you done some more advanced measurements and can confirm that madVR preview is 100% accurate for HDR? (for me this would be capturing HDMI signal as v210 or at least ProRes etc. and then comparing it to original file which was used for playback). |

What I can tell you is that MadVR in passthrough mode gives me as good as my UB900. That's good enough for me. If you want to perform further tests, why don't you do so and report back for those who might be interested? I'm not but others might be.

By accurate I mean if data which I play is passed over HDMI to TV untouched for Pass Through mode (goes through proper and accurate YUY<=>RGB conversion, etc). How it looks and is processed on specific TV is a different matter.
I want to make sure that correct signal hits TV, like I have in case of pro SDI/HDMI card. I assume this is the case, which is great. I hope we will get custom HDR metadata injection soon, which can be sometimes useful. |

If the format is some variant of YUV444 the quality loss won't be very big, but there might still be rounding errors from the roundtrip conversion.

Dear Friends
I would like to ask, if I can use madVR without dedicated GPU such as GTX 1070 etc., only with CPU with integrated GPU like Intel 630? What is the best choice of CPU to use with madVR to UHD (HEVC), to have rendering lower then 41,71ms for 3840x2160 @ 23.976 (no dropped, repeated, delayed frames)? Thank you in advance.

Perhaps the i5-8400 or better (the 192 core UHD 630)? Get 3200 MHz memory too. 4K HDR->SDR with madVR is hard with the memory bandwidth available on iGPUs.
The Ryzen 5 2400G might also be a good option but I haven't heard many reports about it yet. It is also important to give it 3200 MHz ram. NGU likely being slow on Vega isn't a problem because you aren't running NGU on a iGPU anyway.

So at least here, Asio4all and Asio2wasapi don't work with 39x.xx on Windows 10 Pro x64 1709 16299.248, and it's not only with REW, jRiver doesn't see the nVidia HDMI out either. So this points to either nVidia or MS. As I don't know which build of Windows 10 Necairiel is using, I have no idea which of these two is at fault, but it's neither the Asio driver nor the application itself. Anyone with relevant info on this please PM me so as not to clutter the thread.
