For some time, a "Class 2" HDMI cable (part number BN39-01583B) supplied with a Samsung 4K 60 Hz display sometimes causes the display to overlay a few horizontal lines of flickering pixels of random colours and sometimes drops out, particularly on content requring HDCP.
Since changing the cable to a thicker Class 2 unit, this problem has not occured again - do you know of other marginal "Class 2" HDMI cables supplied with displays?
