I have a feeling that some folks that are having (cable related) issues is due to EMI interference that may be affecting the signal from the adapter to TV.  Since the CA-1070 is an active adapter, there may  be a possibility that EMI interference could be being introduced unless the adapter is filtering as well.  I can say that the cable with Ferrite Choke worked when 3 other cables worked up to a certtain point.   Some systems may not introduce as much interefence as others and also depends on if cables cross power cables from PC or other devices..
Amazon Basics Std cable: 4K/50Hz and 4:2:2 color
Amazon Basics High Speed: 4K/50Hz and 4:4:4 color (unstable)
HDMI cable with good sheiding and Ferrite Choke:  4K/60Hz and 4:4:4 color (stable)

I was able to achieve a stable 4K/60Hz with 4:4:4 color on my nVidia Titan + CAC-1070 + Samsung JU6500 using a ferrite core EMI shielded HDMI cable.  I was only getting 4K/50Hz and unstable 4:4:4 with Amazon Basics High Speed, but with a better shielded cable and ferrite core I was able to get a stable signal at the higher bandwidth.  The Ferrite core attenuates high frequency EMI/RFI electronic noise.
