I meant exactly what I wrote to help you. It helped me. https://www.tomshardware.com/reviews...60,4063-4.html
This is a 4GB card fwiw.

Yeah, mine is SSC 8-pin so yours will be different. Oh well, happy new year.

@ace I have watched many UHD Blu-rays in SDR via madVR (with Mediaportal and MPC-HC) and have never seen anything like your screenshot (which is massive btw, not great to insert inline in a post).
That looks to me like a decoding problem. Are you sure the output of the decoder isn't truncated to 8-bit or something like that? Please link to a screenshot with the madVR OSD visible during playback, and if possible a screenshot of the video decoder filter's config/its output pin properties.

Truncation would not result in something like that, the extra bits are not for brighter or extra colors. It would look posterized or banded if it was truncated but not darker.

Well look at the lighter parts of the sky and the Fox logo, it is posterized and banded.

the shown effect shouldn't be from truncation or rounding alone but that doesn't matter. it's clearly not what should happen.
the video result is similar to the days when 10 bit x264 was new and older software couldn't handle it properly while still accepting it. i pointed to DXVA2 decoding in the original post of him and he ignored it so... |

HLG support
Greetings madshi. As you know, most 1st generation HDR displays lack support for HLG. This is especially true of low cost projectors. ATM it seems only the Panasonic players have the ability to convert HLG to PQ so that these can be displayed properly on such devices. Would you like to look into the possibility of adding HLG-->PQ mapping curve to the madshi renderer so that HLG content will be output as PQ? Many thanks and best regards, |

If my display has better WCG coverage in DCI-P3 than REC.2020, is it possible or wise to convert rec.2020 into dci-p3 with MadVR?
And what's the recommended settings for 4K content to a 4K display? edit: just did some "simple" calculations on the WCG info I found, so it seems there's no point to do conversion, but my calculations method on the matter could be totally wrong!? dci-p3 - 45.5% perceptible to human rec.2020 - 75.8% perceptible Q70R ------ DCI P3 xy 87.83 % DCI P3 uv 93.67 % avg: 90.7% 45.5 * .907 = 41.2685% avail Rec 2020 xy 65.37 % Rec 2020 uv 73.92 % avg: 69.645% 75.8 * .69645 = 52.79091% avail

i have to miss something important because turning HLG to PQ is trivial and madVR doesn't support HLG yet so sounds logical to me to add this.
you convert it to linear to get linear 1000 nit then you divided by 10 to get linear 10000 nit and now you turn it to PQ set the meta data to 1000 nits and you are done. |

Of course for this to work, you would also have to tell your screen that its receicing DCI-P3 data, if you can't do that, its not really a good idea to set it up like that. Another option would be to calibrate your screen with a colorimeter, but that requires having such a device, of course.

Hi huhn and El Filou, okay under "Built-in Video Decoder Configuration->DXVA2 Copy-Back" I changed it from "D3D11: Nvidia GeForce GTX 1080" to "Do Not Use (Recommended)" and the banding/posterization went away which is a huge improvement. Now Movies & TV player: Vs PotPlayer: Windows Movies & TV player still gives a more vibrant, less dull image with a bit more detail, even without me trying to set the peak nits or any other setting. Here's how I set it in MadVR: Edit: Okay after changing "desired display gamma" from "BT.709/601 curve" to "pure power curve" and "tone mapping curve" from "BT.2390" to "clipping" my PotPlayer image is nearly identical to Windows Movies & TV so I'm happy Thanks again huhn and el Filou for the excellent diagnosis.

you are missing white point which can play a huge rule in this depending where you got the numbers from.
bt 2020 is currently used so the TV knows the input format it usually only holds DCI P3 D65 information the rest is blank. the point of BT 2020 is that the TV expect this format when an HDR signal is send to it or you can tell your TV the signal is BT 2020 so it can color match it that's not the case with DCI P3 which is D65 D63 or D60 and the "gamma" is 2.6 or sRGB. it's a mess. |
