Seems not all "HDMI 2.0" or "High Speed 18Gbps" HDMI cables can carry 4:4:4: at 4K@60Hz and it's seem to be hit and miss depending on brand and length. I recent got this: HDMI 2.0 Cable - Braided Cord 15 ft - Ultra High Speed 18Gbps Wire - Gold Plated Connector Tip(s) - Ethernet / Audio Return - Video 4K 2160p @ 60Hz:

I'm using mine to connect my PC with a EVGA GTX 970 to a Pioneer VSX-830-K receiver then a 6ft HDMI 2.0 (I know this one works as I used it to connect between the PC and TV before I got the receiver) to my Samsung 4K display.While it works at 4:2:0 at 4K@60Hz. The moment I switch over to 4:4:4. the screen start cutting in and out. Does anyone have links (Amazon if possible) to a known good 10ft HDMI cable that will work at 4K@60Hz at 4:4:4?

It's the same story with DP 4K@60Hz. It would be great to collect the cables that actually work.
So far the only cables that worked for me were the ones bundled with the monitors. At 1440@144Hz and 2160@60Hz, the ones I purchased couldn't hack it. Either the video cutting in and out, or no signal at all.
 
HDMI is a lot more forgiving than DP. Anything at least 28awg can handle up to 10 feet at 4k 4:4:4. 24awg is good out to 25 foot runs.


Chances are your receiver does not support 4:4:4. The Silicon Image Sil9777 chipsets were only finalized at the end of 2014. Only a few TVs do hdcp 2.2 and 4:4:4 right now and they only started coming out a few months ago. I suspect no receivers are 4:4:4 capable until holiday 2015.
 
After trying two $40 cables from the local electronics/appliances box store, which only worked intermittently, I got the following, which works perfectly.

AmazonBasics High-Speed HDMI Cable - 6.5 Feet (2 Meters) Supports Ethernet, 3D, 4K and Audio Return

I was curious as to whether I just got lucky, so ordered and tested two more of the same and they work perfectly too.

Note that I got the 6.5 feet (2 meters) length. They offer other lengths, which I haven't tried.

This is with a Nvidia Geforce GTX960 graphics card and Samsung UN50JU6500 television (on HDMI1 port on the TV). I don't know if there are any graphics cards out there, other than those in the Nvidia Geforce GTX900 series, that support 4K 60hz 4:4:4 HDMI.

Good luck.
