These HDMI cables are doing their job. Beautiful film display, and good sounding audio.No problems / no failures, whatsoever, at this time.Very good cables!!I will follow up in the future, with an update on their longevity.
I recently purchased a new 65" 4K Ultra HDR LCD TV. After installing the new TV and going through several procedures to "fine tune" the unit, I was unable to attain the quality of picture that I was expecting. After further research I decided to purchase new HDMI cables even though my old cables were fairly (about 2 years) new. Long story short, the new Monoprice cables made a significant positive difference. As an added benefit, my HDMI ARC signal to my stereo system had been unstable and the new cables completely eliminated that issue. My recommendation is, if you are experiencing poor video or HDMI ARC audio issues, change your cables with HDMI certified cables. Monoprice prices for certified cables can't be beat.
