4K TV's with 4:4:4 subsampling available in SA

[donaldza]

Hi everyone,

I'm trying to see if anyone here is using a 4K TV as a computer monitor here - and, if so - are you able to get subsampling 4:4:4 on it @ 60Hz?

If you're not using at least HDMI 2.0 or DisplayPort 1.2 - your answer is no

Please share model numbers - I'm trying to source on in SA.

Cheers,
D

Cool beans, are you connecting to this over HDMI 2.0 ?

I don't suppose you could load this torture image on that screen : http://www.ozone3d.net/public/jegx/201412/chroma-subsampling-test-4k-tv.png and take a picture of it so I can check quality?

What size are you looking at? There is a 40inch 4K monitor available in SA. It's priced very well, however, it's like a hit and miss. Some people have issues some don't. I was lucky, mine works brilliantly and no issues at all.

40" is what I'm after, still has decent pixel density at that size

Had this now for more than month and am very happy.

I was also thinking about this recently. Only problem was, my GPU doesn't have HDMI 2.0, and finding a display port TV is not that easy locally.

A 40" 4K panel has higher pixel density than a 21" 1080p display(probably the same as a 20"), and you will probably be sitting further away from it. So you should be good.

I'm using a 49" LG. 49UF68
Port 1 is HDMI 2.0, connected to a MDP 1.4 to HDMI 2.0 adapter. Got both the HDMI 2.0 cable and MDP adapter on Amazon.

Getting my full 60Hz after some tweaking with SwitchRezX.

Yeah I am too, but not chroma 4:4:4 - can you check that torture image and see if you can read all lines clearly? (share pic of possible)

I had my eye on this one but came across some mixed reviews, do you know of any stores that carry these so I can check it out?

+1, I'm also shopping for a 40" to use as my gaming monitor.

I don't play competitive FPS and as long as I have >40fps @ 60hz I can't be happier - so seems like better value than paying 12k plus for a monitor right.

Anyway, I came across this page which seems to have some decent data

The LG EG 9600 seems like the way to go - but 55" won't work.
So the next best going for a 40" looks like the samsung JU 7500 - but I'm a bit concerned over the response time.

I use a Samsung 50 inch JS7200, the JU6500 also works. Basically all J series Samsungs. The only issue with Chroma is that you have to switch it into pc mode which sacrifices a lot of eye candy. So I rather go 4:2:2 with UHD color on, looks amazing and for some reason red text etc still looks great

What do you mean by losing eye candy? Surely Chroma 4:4:4 would be sharper ?

Dynamic Contrast, Black levels, those things looks much worse and the sharpness does not compensate for that. Running a Samsung Tele in 4k makes it look like a Hisense, takes away all the processing and gimmicks that makes a Samsung stand out. A Samsung tele is only rivaled by the LG OLED tvs, check rtings.com for scores to get an idea

OK, but you CAN actually do 4:4:4 @ 60Hz on this screen ? Could you perhaps do a me a favour and try that torture test at 4:4:4 on your screen?

I've done the test can guarantee you that it works, it's what the UHD color option is for. Will take a pic for you tonight when I get off work, I was in the same boat as you but I wanted a 50'' from the get go since I use my tv for console gaming as well. Had to import a hdmi 2.0 cable from Amazon just to get 4k to run @ 60hz. But that was last year when HDMI 2 cables were almost none existent in our country

Cool man thanks, just wanna be sure before I spend a fair amount of cash

If you do decide on one, let me know how it goes for you. I have the Samsung HU7000 (got it for R8k on a takealot special) and while its decent, and I use it, I really want chroma 4:4:4 for my photo editing.

Pics attached! 2 are 4:2:2 and other 2 are 4:4:4 both with UHD color on (check bottom right corner in image then you'll see 4:2:2 or 4:4:4). Struggling to get good pics really, looks way better in person

Where did you buy this TV? And how much did you pay if you don't mind sharing?

Sorry, forgot/missed this thread somehow.

Pic opens top left corner in browser and full screen in OSX Preview. Images of both attached. Much clearer in real life though.

this looks like 4:2:2 IMO - still good - I ended up going with the Samsung SUHD which can do 8bit 4:4:4 @ 60hz (confirmed) - also 10 bit color but not 4:4:4 @ 60hz

 

[Dirtdiver]

how do you tell if its 422 or 444 by looking at the pic?

I'm also looking for a 40" UHD TV to use as a monitor, but it seems like there are no options locally
