It has been mentioned that only the nVidia Geforce GTX 900 series has an HDMI 2.0 output, necessary for 4K/60/4:4:4.

If any information in this post is inaccurate, please say something and I will correct it...
The following computer "video" cards will do UHD/60/4:4:4 via SDI and HDMI 2.0 connections ...

Blackmagic Designs:
DeckLink 4K Extreme 12G and 4K Pro
UltraStudio Thunderbolt 4K Extreme

AJA Video Systems:
KONA 4 Card
Io 4K and XT

There are several more video cards from both manufacturers that will do 1080p/60/4:4:4

I would guess that Matrox also has video cards that will do UHD/60/4:4:4, but I'm not familiar with their products.

Those are capture cards, not video cards. It's confusing to refer to them as such when that term almost always refers to computer graphics cards.

Since I work in professional post production my home-user vernacular might be off ...

In my circle these are referred to as video cards, video I/O cards, or occasionally SDI cards (from the pre HDMI era). I've not heard them referred to as "capture" cards for 15+ years. Actually most of the newer cards do not "capture" video anymore - almost everything is direct to/from disk these days.

I just checked the Nvidia and ATI websites ... both refer to their computer-monitor-driving OpenGL, Cuda, etc. cards as "Graphics" cards, and not video cards.

Whatever you want to call them ... these cards will allow one's computer to correctly output a 4:4:4 signal to test monitors.

Let's move on.

To get back on topic, it looks like the low-priced Sharp Aquos 2015 models don't support 444 at UHD 60, making them unsuitable for computer monitor use.
The 70ud1u does in fact support 4:4:4 @60hz on hdmi input 3. I can only assume that the 60 would as well as the only difference is the obvious size.

No confirmation. I found it on google but I can't post the link because I don't have enough posts.
If you google "Xiaomi's smart Mi TV 2S is almost ridiculously thin" it's the first hit.

You can only order within asia right now (china?). If I could order it I would! I'm hoping it becomes available outside asia soon.

The motion rate and PQI of the 6400 is less than the model 1 step up fyi. Hope that helps your research.

Question Please help...

I just bought a XBR75X850C. Absolutely love the TV. Construction is what I love and has me completely bummed out. I love the fact that it's all metal and build quality is top notch, but it fails at 4:4:4... I bought this to run on a PC and I have to run 60 Hz.

Looking at this list is seems the JU7100 is my only option for a 75in that will do 4:4:4? I don't do curves at least on TVs. Anything else going to have it that size or greater in the future? The curved TVs I e seen have warped bezels and it really bugs me.

Thanks so much for the help. Is the JU7100 a plastic frame?

Love this thread.
Would welcome all discussion & verification of sets.

Keeping this thread up-to-date would be a big help to those in the market for 4K televisions that want true 4:4:4 and 60Hz.

The AX800 Panasonic also does it via HDMI Port 4 with a Nvidia GPU 900 series or above. I am currently running using a Nvidia Titan X GPU in SLI. I have a Denon 4k receiver that does 4k/60fps 4:4:4 passthrough, so enjoying 4k 4:4:4 60fps gaming at 7.1 audio through my receiver hooked into port HDMI port 4 on the AX800.

The newer Panasonics CX850u has the ability on all HDMI ports as Rlindo mentioned above.

I just bought the Samsung 40JU6700 to use as a monitor and I have not been able to get it to display [email protected] with 4:4:4 chroma. The signal defaults to [email protected] wit 4:4:4 but when I switch it to 60Hz it drops to 4:2:2 (as verified by the test image posted here).

I may be doing something wrong but if I cant get it to work it is going back soon.

FYI I am using the HDMI1 port labelled STB/DVI and have tried the PC, Game and DVI PC modes. None of them display 4:4:4.
I have tried PC mode on all the other HDMI ports as well with no luck.

[Edit - Solved! I had to enable the UHD Color setting for the HDMI1 port]

I have a Samsung UN65HU9000 hooked up to a custom pc with a 980ti card doing [email protected] 4.4.4 and the screen goes black for a few seconds and then back on at random times. I have changed HDMI cables and have turned off numerous settings on Tv with no help. This has happened with other video cards on the nvidia 900 series also. Thanks in advanced with any info/help provided.

That is the exact behavior I have seen with 4K TVs and a cable that can't consistently carry 18Gbps.

How long is your cable run and what kind of cables are they?

First one was monoprice Highspeed Cable about 10ft I think, second one was twisted veins about 3ft but got no signal most of the time. Now I have a Amazon basics highspeed 6.5ft cable. Thanks for the reply

All Vizio 4K TVs are 4:4:4 capable. The test patterns everyone has been using test for 1:1 pixel mapping and not 4:4:4. The Vizio 4K TVs scale the pixels ever so slightly and that causes them to fail the test patterns that everyone is using. However, they are certainly 4:4:4 which is far more important than the 1:1 pixel mapping.

A lot of people have been saying that 4:4:4 isn't important because the TVs that the reviews said weren't 4:4:4 capable still looked identical to the other TVs for desktop use. The only thing they fail at was showing the test pattern. However, the test pattern does not tell you if the TV is 4:4:4 or not. It just tells you if it is 1:1 pixel mapped.

Don't take my word for it. Go try it yourself. The new Nvidia drivers allow you to select 4:4:4, 4:2:2, and 4:2:0. Just have a look at what the text on the screen looks like when you switch between those settings. You will see that at 4:4:4 everything looks great even on the TVs that are said to only be 4:2:2. However, once you actually force 4:2:2 mode on those TVs you will see the color bleed that the 4:2:2 and to a greater extent 4:2:0 compression causes.

These pictures are all from a Vizio M80-C3. It is 100% 4:4:4 capable for 1080p @ 60 FPS, 1080p @ 120 FPS, 4K/UHD @ 24 FPS, 4K/UHD @ 30 FPS, and 4K/UHD @ 60 FPS. The reviews are simply testing for it incorrectly.

4:4:4 on the Vizio TV


4:2:2 on the Vizio TV


4:2:0 on the Vizio TV

Your Nvidia GTX 970 is capable of outputting the full 18 GB/s. It can do 4K/UHD @ 60 FPS 4:4:4 to any TV.

The 2014 Nividia cards do not present the option to do 4K/UHD @ 60 FPS 4:4:4 to the user. Instead they only offer 4K/UHD @ 60 FPS 4:2:0 which is terrible and looks extremely bad.

However, the 2014 Nvidia cards allow the user to select either 4:4:4 or 4:2:2 for 4K/UHD @ 30 FPS. The 4:4:4 option is very good there.

Can anyone else corroborate the Vizio 4:4:4 claim?
I'm specifically interested in the VIZIO M-Series M43-C1 43", can it do 4K @ 60 FPS 4:4:4?

If you have a 2014 Nividia card it will not do 4K @ 60 FPS 4:4:4 because of bandwidth issues. The only option for 4K @ 60 FPS with the 2014 Nividia cards is to use 4:2:0. It looks terrible and is not usable at monitor sitting distances.

The 30 FPS really isn't that bad. I am not saying it is ideal like 4K @ 60 FPS is. However, it isn't as unusable as 4:2:2 and 4:2:0 are. I would take 4K @ 30 FPS 4:4:4 over 4K @ 60 FPS 4:2:0 every time for monitor use and I bet you will say the same thing if you try it.
