Just a heads up Monoprice has a three pack of 5' ultra high speed hdmi cables on sale for $9.45 shipped. Not a bad price if you are upgrading to 4k and need new interconnects.
I think you're right, John. I replaced my collection of cheap, mismatched HDMI cables with new high speed cables a couple of months ago and I went by speed and not product description when purchasing them.I think it's best to go by speed (18Gb/s) rather than vague descriptions. If they're certified 18Gb/s then you should be set for 4K/60 HDR. Monoprice always includes a certified bandwidth, as I recall.
