To the point...yes, it's what you need, what you're looking for to build up or enhance that home theater of yours. I use it for mine. Yes, it does 4K flawlessly as advertised! All other reviews are accurate and dead-on. I would buy this HDMI cord again. Worth the wait of shipping to get your HDMI cords in bulk from Monoprice as opposed to the price in your local retail stores. The HDMI cord is durable and great quality. I'll definitely buy more here again if/when needed.
Monoprice has the best HDMI cables -- period. Bought two 4 ft male HDMI cables to hook my laptop up to my TV and works perfectly. Gave one to a friend. For the price of the two cables and even with S&H the total cost was less than one HDMI at Wallyworld or anywhere else.
