HDMI Cables
Effective 7/24/18, our dear friends at Spectrum are going to require a digital box on every TV.
Been using the HDMI cables that come with their boxes, and I'm wondering if upgraded HDMI cables would improve video performance.
Any thoughts?

Re: HDMI Cables
Supposedly, if it's a short distance, like 2 meters or less, it shouldn't. Also, on paper the way HDMI is supposed to account the digital packets sent and received it shouldn't.
If you are going to view 4k, you want a HDMI that says "high speed" and I believe 18g compatible.
Some years back when I first bought my processor, I bought a $40 I think Belkin HDMI. The audio wasn't right. I tried everything to cure it. I was about to take back the processor when I had an idea to try another cable. I bought a good quality Tributaries and it worked, problem solved. My vision, even then, wasn't good enough to tell reliably if any video benefit. I suspect if the audio was poor, the video probably was affected in some way.
I've also had HDMI cables, cheap ones, go bad. It made the picture go black intermittently. I thought the TV was messed up, come to find out problem cured after replacing the cable.
So I don't go crazy on cost, use mostly a mid price Tributaries. I'd rather spend the money than have issues I have to deal with.
Back to the processor for a moment, that $40 cable worked when I tried it from a BDP to TV in my daughter's room. So either the satellite receiver stream wasn't on par or maybe the Marantz demanded a certain quality signal. Not sure. But, I am admittedly one of the suckers that will spend for better HDMI. .
On longer runs where the signal is getting weak it's said to cause like white flecks to show on screen. If one goes bad, or, the run just too long, you'll just get a black screen.
If you have a shop you deal with they should be able to lend you something HDMI to see if you notice a difference. If you do a comparison I'd be interested in knowing what happens.Aurender ACS10 w/Audioquest Diamond USB, Esoteric N05xd

Re: HDMI Cables
In order to better comprehend the HDMI optical cable, the meaning of HDMI is the first thing we should get to know. HDMI stands for High Definition Multimedia Interface, featuring the extraordinary capability of signal transmission. For example, the latest specification HDMI 2.0, which was released in 2015, supports a maximum bandwidth of 18 Gb/s. HDMI interface has become a mainstream solution for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for analog video standards. As the data amount is increasing day by day, a new demand for larger and faster data transmission has shown up, which means the copper cables are far away from satisfaction. Therefore, companies with vision, like 10Gtek, has released its HDMI AOC (active optical cable) series products in a bid to win the market.

Re: HDMI Cables
Fiber optic is not really needed unless it's going to be a long run.

Re: HDMI Cables
In my experience, upgrading short-run HDMI cables resulted more in a slight improvement of sound quality with no discernible difference in video quality. Upgrading a longer run, 7m, resulted in a slight improvement of both sound and video.

The original BD "Dunkirk" has a known defect where the audio cuts out on loud battle scenes. It's been corrected on the 4k version. I've had maybe 1% defective discs out of about 500 or so,...
