If you are looking to push 4K HDR content from your PC to the projector - get this cable.4K 10 bit at 60Hz no issues at all.Great build and quality. Highly recommended.

No reviews for Koreans who bought this productI worriedButIt connects to my Radeon 7+ Samsung TV and it works very wellgood

Excellent

Great picture

This cable replaced a 40 ft Monster Cable standard HDMI I had been using previously; that super thick cable would have dropout (black screen) issues at 4K / 60. The ATZEBE Fiber Optic 50ft ft cable is very thin (due to the fiber-optic construction), so it\'s very easy to route behind my couch and through wire management channels.This cable is uni-directional (as are most fiber-optic HDMI cables), so make sure you have it setup correctly: plugged the "Source" labeled HDMI into my receiver and the "Display" HDMI into my 4K projector and it worked right away with both my HTPC and PS4 (tested 4K/60 w/HDR on both). I can\'t attest to the reliability since I just received it, but 8 hours of use so far and not a single dropout/black screen. Good value for the money! Now if they would only change the brand name...ATZEBE?!?
