Recently took delivery of a Samsung 4K TV screen after our old one went “Pft-fizz” and died a few weeks ago. Lovely definition, terrific picture, decent sound and intuitive setup with our DVD player and AppleTV box. One problem. When streaming a movie or TV show, every so often, the sound blanks off and needs to switched out to the main menu and back again. An evening with a stop watch found no pattern. Swapping the ports likewise. A total pain in the bum and an annoyance because as is the nature of these things, it always failed just when on screen stuff was getting vaguely interesting. Mrs S was reduced to snarls and loud shouts of “Bill!” Sometimes less than two minutes after I’d got the sound working again. Dark noises were being made about “Taking the bloody thing back.”
So I did what I always have when stumped for an answer, gone and checked out the support forums and tried all their solutions. HDMI connections were checked. Ports swapped (again). Firmware updates checked (Both for set and streaming box). All the suggestions on the Samsung support forums were tried and failed. Then I checked my cable specs. I’d bought my HDMI cable at the same time we bought the AppleTV box some five or so years ago. At the time it had been top of the line, 12Gbps full bandwidth and operated flawlessly. So what had changed? In the end I went shopping to one of the local electronics emporiums and put my reading glasses on. The answer had been staring me in the face. My old HDMI cable was not fully 4K compliant. Almost, but not quite. So I got out my wallet and stumped up for a full on 18gbps HDMI cable with gold plated connections (All right, it was on sale). A couple of hours after fitting I’m fairly sure the sound is fixed and domestic harmony is restored to the Sticker household. Well, for now. Until the next wanked-up Windows 10 upgrade.
