Re: you wouldn't use a cat 5 patch lead and expect 10Gb/s performance
HDMI, last time i looked, doesn't even have error detection never mind correction or retries, so if the data is wrongly received it stays that way.
Which you can see, with your eyes....
So better make sure you use a decent cable. Or maybe not.
True, but 'Decent' just means 'up to the job', and the cheap 2 quid HDMI cables are up to the job.
I have a friend who works for an A/V place, and have stopped asking him for free HDMI cables as he always gives me some super thick braided mostrosoty, which I find generally worse than the cheap 2 quid amazon basics ones I buy. They're too thick so don't stand a lot of flexing and break quite easly, and in some instances are so heavy that they slowly work their way out of any verticle HDMI ports I have.
Cheapo amazon basics tend to just work.
