One of the best HDMI cable?

For 4k the quality of hdmi does matter: http://archimago.blogspot.nl/2017/01/quickie-post-yes-cables-matters-for.html

Don't look now, but there is a new and improved HDMI cable that is 2.1 !   If you care to, you can  read an article from Dec. 4, 2017 from TechHive entitled "2.1 HDMI specs and features : Everything you need to know."

I have been through a dozen high end HDMI cables, purely for Videophile useage, not audio. Most made no difference. Some expensive cables were worse than stock (Chord HDMI Active, i'm looking at you).

But the best was the Mapleshade Vivlink 2 with Plus Upgrade. And its affordable. Only negative is Mapleshades usual ridiculous construction technique, but that is a necessary part of their performance.

It really depends on cable length. For 3-6 feet any decent cable will do. For lengthier ultra HDMI certified (Blue Jeans and others mentioned) will be more solid choice. But from 20 feet and up - no copper wire will push "full 4K resolution", ie. 18Gbps. Only newest active fiber optics cable would work without Metra Gigabit Accelerator
I changed 2 monoprice Redmere and Audioquest Forest cables before I finally got full 4K to my projector via 50 feet HDMI - RUIPRO HDMI Fiber Cable. For more information -avsforum has huge thread dedicated to tests of HDMI cables throughput, guys did an amazing job measuring and comparing, an absolute impossibility in audiophile world.

yes, Belden - get one that is certified for high speed and don't waste $$ on things that don't work

what you may need tho is outstanding HDMI interface - read the white papers for the new Oppo 205 and it's carefully engineered HDMI interface
