The HDMI specification allows 1 bit error every 8 seconds with a 1080p {1920x1080 pixels} @ 60 frames/second image.
At higher image resolutions that error rate would be found in fewer seconds (however long it takes to transmit 1 billion pixels). For example for a 4K display that would be maximum allowable error rate of 1 error every 2 seconds, and for an 8K display it would be no more than 1 error per half second.
HDMI cables must be as short as possible, but no shorter (ie no stretching of cable to reach your display; cables should be able to route without stress). So choose the length carefully by measurement. (An excellent means is to use string or small diameter rope and go from source to receptor, which will soft lay like a cable should, and then measure the string).
Always good practice with any cable, this has been found to be even more important with HDMI, as the connectors (both cable and component) have proven to be weak and prone to damage. Bit errors increase with HDMI cable length.
Do not listen to anyone who claims that HDMI is a digital signal or that "bits is bits". They are wrong. ALL digital transmission is via an analog signal that represents digital data. All digital data cable is subject to the same criteria that any analog signal is subject to, and can be damaged in the same ways. So handle gently, don't bend too tightly, and in general don't treat a digital cable like it owes you money and won't pay.
I know this site in general has a lot of Monoprice love and Audioquest hate, but I've never seen an Audioquest speaker cable made of Copper Clad Aluminum, like Monoprice's 12GA speaker cable is. So, buyer beware. There are many alternative suppliers of known good cable at reasonable prices, if that's what you are looking for.
I can't buy a Monoprice HDMI cable and cut it open, like I do with many commercial cables for my own personal reference, because Monoprice charges $50 shipping for any package, no matter how small, if you live outside the US. But my trust level of Monoprice has fallen a few notches; I would want to know what I am buying before I would recommend them in the future. Maybe someone here can do so and report back.
