HDMI 2.0 4K 4:4:4: cable

[qubit]

I am desperate for 444 because my TV supports 60hz 4k&1440p only with 444.
Thank you for your suggestion i will follow your words.Can you please suggest me a 5m quality hdmi cable?
I found a repeater that i think will work.

Nothing wrong with wanting to use the best quality signal, I'd do the same myself. That repeater looks like it would do the job and is quite cheap, so I think is worth a go, even if you find a single cable later on.

I'm not really sure what brand/model of HDMI cable to recommend for long lengths, but I suggest googling for it. I've seen articles about this sort of thing where they do name such cables. Monster cables are likely to be good, but you could end up paying silly money for it (perhaps a 100 Euro) so aren't worth it. There should be good quality alternatives that cost much less.

Make absolutely sure that the cable is labelled as "High Speed".

I had a quick google for "good quality hdmi cable" and came across the article written below by Geoffrey Morrison, who knows what he's talking about. It will make a good starting point, too. Also check out those active (signal booster at the plug) Redmere cables as I think they have ones made specifically for long lengths. Again read up on them before spending lots of money.

Hope you find it.

After trying two locally purchased $40 supposed HDMI 2 18gbps cables that worked only intermittently for 4K 60hz chroma 4:4:4 with an Nvidia GeForce GTX 960 card, I had success with various length versions of the AmazonBasics High-Speed HDMI Cable from Amazon. That includes the 25 foot version, that I bought out of curiosity... worked fine. It appears to now be discontinued, in favor of a new model which presumably will work just as well. The link to the new model is on the page. Very affordable and can always return if doesn't work out.

Yeah, the Amazon stuff is good quality. Glad you eventually found a cable.

I have tried so far 5 cables including a 70€ (18gbps/600Mhz/5m) but nothing worked in 4K60Hz 4:4:4 only up to 4:2:0/8bpc.
I have been reading from people that the Nvidia 10xx series have problem with hdmi 2.0 and i should try Displayport to Hdmi2.0 adapter.
An other strange thing that is occured is that TVs HDMI2 port plays with all cables till 4:2:0 (supports only hdmi 1.4) but HDM1 port (that supports hdmi 2.0)
doesnt play with all cables at 4K 4.2.0 only with 2.With the other 3 cables till 1080p.
That is strange
Maybe thats a TVs HDMI port failure?

@Philippos Have you tried an AmazonBasics HDMI cable like @SpringfieldMH did? Seems that's the solution, see his post 27.

Yes i tried the same cable but doesn't work for me with the GTX 1070 and LG 55UF6809.

The manual is very sparse on details about HDMI. The only place it gets specific is in relation to the "ultra deep color" options.

Manual is very clear that 3m cables or less should be used.

HDMI Licensing also certifies cables for compliance. Basically you have to go to a store and look for the premium high-speed cable anti-counterfeit sticker.

I went almost to all the local stores but i found only expensive high speed hdmi cables and none premium certified.
I live in Germany and i thought finding a premium certified cable would be easy but it is thougher than i thought...
Also there are people that claim a amazon basics HDMI cable at 7.6m/25ft worked so maybe lengthier cables than 3m work at ultra deep color.
I hope that isn't a TV or a graphics card problem.

It's really a crapshoot because HDMI doesn't have strict cable specifications like VESA has established for DisplayPort, DVI, and VGA.
