QualGear High Speed HDMI 2.0 Cable with Ethernet (3 Feet) - 100% OFC Copper, 24K Gold Plated Contacts, Triple-Shielded. Supports 4K Ultra HD, 3D, 18 Gbps, Audio Return Channel (QG-CBL-HD20-3FT)

Quick delivery, all look heavy duty and like they will last. Took my old cable only able to put out 60hz and brought my refresh rate up to 120hz on our 4k TV! Unfortunately only 5/6 of them work, however for the price I'm willing to accept the one cable not working.

I initially tested this cable by hooking up my laptop to my standard 1080p computer monitor and there were no issues, so for that application it seems fine. However, after using the cable to hook my Xbox One S up to my 4K TV, it soon developed problems. The HDMI signal keeps flickering on and off, making it impossible to play games. I swapped cables and the flickering issue stopped. I suspect that this cable isn't actually HDMI 2.0 as advertised, but an older spec.Will likely return it.

They're cables and they work. They move signal from one end to the other.

Not HDMI 2 compliant despite advertisement.Using 4K 60hz at anything above 4:2:0 causes the display to flicker and glitch when connected through my A/V. A shorter cheap cable works far better without issues.Not impressed.

Works
