Once you go over 1080p, I found that most (>50%) HDMI cables that advertise HDMI 2.0 (or even 2.1) either do not work at all, or have constant cutouts at 4K@60. Also I found that there is no correlation between how nice cables look, how expensive they are and how well they work.
The only HDMI cables that I had 100% success with, were the ones that came bundled with A/V equipment, even if some of them look like bottom shelf stuff.
