Guys, For HDR 10bit, on nvidia 1060, Does setting 4:2:2 10bit/ 12bit on the NVIDIA control panel make a difference ? OR, does it auto pop to the correct output setting when NVHDR is engaged..
And also, does setting 10bit in the Madvr control panel cause issues for 8bit outputs ?

madVR's dithering is better than the GPU's, and you don't want to double dither if you can avoid it, so it is better to set madVR to the same bitdepth as the GPU (or lower).
For HDR I much prefer sending a display 8 bit RGB over 10 bit 4:2:2, madVR will not change the GPU output at all.

Madvr will be sending 4:2:2 12bit ? I'm confused as to how this works, because it's suppose to output -Limited- range, but the desktop looks exactly the same as full range. And in madvr control panel, if i set the display to limited range, it's actually too bright. So, How does it all line up. ?

this is the 3rd time i tell you that madVR will always output RGB to the GPU driver with either 10 or 8 bit no matter what if the GPU can send it is nothing for madVR to be bothered with.
the GPU driver always expects the input RGB to be full range. and sending YCbCr is always limited range only RGB has too ranges. so yes the GPU driver is doing the conversation not madVR. |

Huhn, I still do not understand this entire chain clearly. Is there a diagram for where the conversions happen end to end. Not so much that I don't understand what you're saying, but I can't seem to confirm the difference in end result visually. For example, if I set the NvidiaCP to RGB 8bit, FULL range, When NVHDR kicks in, my Display only tells me it's HDR10.. Madvr top line says RGB 8bit But how could RGB be 10 bit if it's set to 8. How do I know for sure, what the gpu is outputing.

1) LAV video can do a conversion if the render does not support the source format. When using madVR this should never be needed and it is not ideal. 2) madVR will output RGB at whatever bitdepth is set. 3) The GPU driver will do a conversion to whatever you set in its control panel. madVR will never change what it outputs based on what the GPU is set to and the GPU will never change its output based on what madVR sends it. All these steps simply convert any input to their configured output format without a lot of smarts involved. For example the GPU is happy to convert madVR's 8 bit output to 10 bit. You know for sure what the GPU is outputting based on what it is set to in its drivers. Also, I can send my TV 8 bit RGB HDR and it will say HDR10, that is just a brand label for the metadata standard, it works with 8 bit RGB too.

I did try the HDR set you mention, but I could not get the clipping ones to work, or rather get my TV to adjust once in HDR mode, unsure if this was me, or that adjusting for black crush is broken for me on my TV as I read is common in HDR mode. |

I see you are using 385.28 so I presume you have specific reasons for that, but maybe another driver version would help with this? Also, it may be an option to use the High Performance power setting if you have a dedicated HTPC that doesn't see long idle times.

What am I seeing, still 8 bit HDR ?

OK guys, tahnx, I am understands now.. My TV has been Lying to me, that cheatn' whore.. Which driver are y'all guys using for 12 bit ? (nvidia) Does 10 bit work on all drivers ? (nvidia)

You should look and carefully compare 12bit vs 8bit. Many TVs will show colour banding with 12bit input which isn't there when given 8bit. Last edited by iSeries; 25th January 2019 at 17:40. |

For HDR that's a problem that you don't know very well where to start. Obviously it's not very reasonable to ask madshi to support tonemapping for input that doesn't identify itself as HDR, and ffdshow is no longer being developed, so there's not an easy solution. I'm testing now DmitriRender and it seems better than SVP in both performance and visual quality. Unfortunately it doesn't support HDR metadata passthrough either, but at least the developer says he's working on it. |

It is mostly useful to select the output SDR gamma curve for HDR -> SDR. With most HDR displays, it is not advisable to change the brightness or contrast controls because you can offset the display's tone mapping, which is based on the default settings for both.
