So, I just purchased my first 4K HDR tv. I also will be buying a 4K Blu-ray player and a 4K cable box. My HDMI cables have been in place in my stand for at least ten years or so and have worked without issue. I believe I purchased them at Monoprice way back then. I had a peek at them and it says HDMI 1.3 on the jacket.
My question is simple - will these cables be able to transmit 4K HDR images or do I need to purchase new HDMI cables? Thank-you in advance.
Depends- are you sending the signal through an AV receiver, or straight to the TV? In either case, I would say that you may have problems because HDMI is a buggy system. If it flashes on and off, turn off Deep Color. I can say with certainty that if the cables are ten years old, they may or may not work. That's about as certain as anyone can be- sometimes they do, sometimes they don't. 4K requires much wider bandwidth than 1080.
I installed a Key Digital cable in 2014 and last year, it stopped working. It was a Redmere cable, but it's no longer usable with the changes that have come from the HDMI idiots, so I had to drive three hours to reach the house and replace the cable with one that cost less (a different brand), but it has worked flawlessly since. Key Digital told me the cable wouldn't be covered by their warranty, even though it had failed in less time than their warranty covers (three years). The warranty guy told me that since it has four shielded conductors, I could use an RJ45 to terminate it and use one of their HDMI extenders. Right- he wants me to try to sell the customer on a $300 POS from the same company whose cable couldn't provide the video and who wouldn't honor the warranty. I asked him what kind of hillbilly he thinks I am.
See how this works, Key Digital? You piss off a custom integrator and they post bad things about the experience and your company online, for everyone to see.
