Introducing a new surface format doesn't really require anything. It could happen tomorrow. It would just need to be specified somewhere officially and implemented by the graphics drivers.
But since 12-bit content doesn't really exist, or game rendering would want it, its doubtful anyone cares.

For optimal results, DWM would probably need to learn about it, not sure how dynamic it can use GPU compositing functions.

Set 24Hz 12 bit in NCP. Then 60Hz 8 bit. When you play a 24Hz video, it will use 12 bit. If you use madVR to control refresh rates and resolution, it will auto switch desktop at 60Hz 8 bit and video at 24Hz 12 bit. Be aware the setting does not survive a reboot using any newer drivers. You have to reset it or use 385.28 which does retain the setting. 12 bit will most likely introduce banding and you are better off with 8 bit unless you have a rare true native 12 bit display. Most are 10 bit at best.

Because if I select the nvidia default 23hz 4k, it will let me switch between 8 bit and 12 bit rgb full

Now what you actually get out of 12bit is another matter, but no banding that I can see on my setup.

You need to use CRU to create custom res that work at 12bits with recent drivers. Or use 385.28 if you want to use madVR's custom res at 8bits and 12bits.

Hi all. I have just bought my first projector, 2018's JVC DLA X7900 (as it is known here in Australia). It is yet to be installed but, in the meantime, I am upgrading my HTPC and installing MPC-BE with MadVR to ensure the best video quality on what will now be a much larger screen than I am used to. I have thousands of DVDs and blu-rays that I have ripped to a NAS - so I have many video files in 480p, 576p, 720p and 1080p. The JVC has a kind of 'faux' 4K called e-shift, which, as I understand it offsets 2 1080p frames to make up 4K. Is it best to have MadVR just upscale the lower resolution files to 1080p, and possibly save on processing power (and heat/fan noise), leaving the frame doubling to the JVC or get MadVR to take all files to 4K. Whatever I do will need to be 'set and forget' as my wife is only interested in turning the system on and pressing play - not fiddling about. :-)
PC is Windows 10, Intel Core i5-8600, Gigabyte Z370N WIFI Motherboard, Corsair Vengeance LPX 16GB DDR4-2666, with a Gigabyte GeForce RTX 2060 6GB Windforce OC Video Card. Appreciate your advice. Cheers, Allan Last edited by fourbigkids; 15th March 2019 at 23:34. Reason: To add PC details. |

I am using the latest 419.35 drivers and in Windows 1607 there is no issue with remembering madVR-set custom resolution, but in Windows 1809, it stops working after a reboot, even though it seems as if it was saved (at least in madVR settings)... I have to delete it, reset GPU, re-create it, and reset GPU after every reboot...

Pixel shifting looks a little more blurry upclose, but from further back, it's not bad. You have to determine for yourself if pixel-shifting looks sharper at the distance you watch the movie. But if you downscale 4K, that's extra processing load, which may require lowering the NGU chroma setting.

Hi @tp4tissue
As I understand it, you're suggesting that the JVC pixel shifting may be something we like or don't like depending on viewing distance (and probably screen size and throw distance I expect??). We'll be about 3m from a 96in screen and the throw distance is about 3.5m. Not big numbers. We'll have to check it out on installation. Thanks. However, I am not sure I understand the bit about "downscaling 4K". 50% of our viewing comprises old movies, many from the 40's and 50's ripped from DVDs, so in 480p, 576p and 720p. What do you think I should be upscaling those to with MadVR? Or does it all depend on whether I like pixel shifting or not?? Cheers. Allan |

Hey Allen, since you're not displaying a true 4K video and the projector is also not displaying true 4K output, I think you'll find it's not worth the extra processing power to upscale large amounts with a demanding upscaler but you could quickly compare it and see how it looks. You may need to take screenshots to properly know what to look for. NGU standard and sharp should be your go to's depending on your sharpness set on the projector and done with post-processing within madVR.

I have a question about BT.2020, how did I know that I can use it? Does the monitor need to support BT.2020 or the GPU? Or can everyone use the new BT.2020 and it works?
