I'm quite certain my GTX960 4GB can't switch to UHD 4:4:4 12 bit @60 Hz...

no it can't do that you need a profile for it. don't think to much about it.

BTW the nvidia setting doesn't do anything the last time >i< checked. if you send 10 bit to the GPU driver it was sending 12 bit to the screen when possible even when set to 8 bit. my current TV doesn't tell me the input type so i can't do new tests.

BTW if you guys have so much trouble with banding try 6-7 bit it's hard for bad processing to add banding there. and no this is not a bad joke and no dithered 6 bit is fine not perfect in term of banding.

and when we are already talking about bit deep stuff it should be possible to change the EDID in a way that it reports the TV only supports up to 10 bit in this case nvidia doesn't have a chance and has to send 10 bit.

@huhn: I'm not interested but just curious. Is it possible to analyze EDID TV report with some tool and verify if TV supports 8/10/12 bits (I mean through EDID info) or they all accept 12 bits in EDID whereas it's not true in reality ?

Yes, madVR's "identification" shows the EDID info. My TV reports 8bit, 10bit, and 12bit for supported bitdepths but really it isn't very good at anything over 8-bit (2017 LG OLED).

Just use 8bit RGB @60Hz.

And it shouldn't. Nothing can. Anything above 30Hz is not within the current HDMI spec.

I know, but wasn't it you who said above that it works with your GTX 960?

No. I have my desktop set at 60hz 8bit and I match refresh rates at 10bit, usually 23.976 as studios intended them to be played. An occasional 25fps title usually from Europe eBay. All within HDMI specs below 30Hz. Everything is and has been in my sig below.

I think a lot of this fervor surrounding 60Hz is because some displays are limited to it and require it to produce a semi watchable picture vastly improved using madVR fixes. Fortunately, madshi supplied them. I'm all for it and support it although I have no need for these fixes since my display is 120Hz, thus I can use native source rates fluent. The general consensus here does not apply to all users. Those just getting to understand madVR and settings in conjunction with it should be informed imo. To raise fists and start name calling when a spade is called a spade is not becoming nor informative.

Since we are on the topic of colorspaces i have a samsung 6 series 55 inch (mu6300) i5 3570k(overclocked to 4.8) 32gigs of ram on a asus p8z77lk with a rx 560 on windows 10 now idk if im not doig something right or what but i have my amd color settings set to 10bit full rgb and res is at 23.97585 but now when using mpchc or jriver no matter what i get stuck with 4:2:0 ..res is still at 23.97585 output is 10bit the only way i can get it to output 4:4:4 while whatching a movie is to use dxva copy back if i use native or d3d11 no matter what it always defaults to 4:2:0 and won't budge ..now id be totally fine with copy back if I could have not offload to the cpu cuz there is no reason for it at all...not only that if i say switch to 4:4:4 i get micro stuttering and it off synchs the audio but about 2 seconds...no dropped frames just the ques wont fill .4:2:2 will play fine ..i just wanna know if im doing something wrong or . missing something...sorry im on my phone at work so i can't give screenshots atm but i can explain anything that maybe needed as far as my setup gos...im connected from gpu into my sony 7.2 receiver (which supports 4k hdr 8-10-12 bits 4:2:2 and 4:4:4@24/30/50/60) then into my tv

How do you know you are "stuck with 4:2:0"? Are you looking at the MadVR OSD? You may be looking at the wrong information. If you can post a screenshot (link to image sharing site) that may help clear up any misunderstanding.

So, did anyone ever answer why sometimes the "1 frame skipped/repeated every X seconds" is sometimes shown and sometimes not shown on the HUD? Where does it depend on to be shown or not shown at all as info?

it needs time to get calculated. it may have to do with your audio renderer too.

is your TV in PC mode, if not some TV's will lock you mode at 4:2:0. I have my TV's HDMI set to Bluray, in this mode my GFX card locks at 4:2:0 when i chose 10bit. If I drop to 8 bit colour space it opens it out again.

I use bluray setting on my TV as motion controls are disabled in PC mode.

I'm using an RX 550 and find no loss of image quality on my TV when using my desktop colour space set to 4:2:0 60hz, real world viewing anyway, dont doubt there would be some minor differences in slides but the convenience of having everything running without having to create CRU's and profiles works better for me.

As a test, set your desktop colour space to 4:2:0 60hz and see if your problems disappear.

The alternative would be to sack of 10bit and stick with 8bit as most people on here would recommend.

The newer Sonys only display 4:4:4 in game or graphics mode. While in either of these modes you can only adjust BFI. Motion interpolation settings are grayed out.

My 2012 Sony also disables motion interpolation in 4:4:4 mode, I would wager that most displays actually do that.

That might be true for flat panels, but my JVC projector is happy to do motion interpolation with 4:4:4, either 12bits 24p or 8bits 60p.

Panasonics don't do MCFI in 4:4:4 as well...only they call it 4K/1080p direct mode so that's probably the logic of a direct signal path, like direct on AVRs - you're not supposed to touch it, to the extent that 24Hz input is pulled down to 60 Hz because it's can't natively sync to 24Hz but must do some motion processing...What would be the difference between a flat panel and a projector in that regard...price vs expectations?

just to understand, as motion interpolation do you mean soap opera effect mode ? are you all using that for movies?

Motion interpolation in the sense of producing a framerate that looks smooth instead of stepped compared to original, yes.There are other motion compensated algorithms that reduce the blur but keep the original framerate, on many panels it is required to have proper pulldown-free 24 hz....
