HDMI cables used to be a great example, but now there are something like 8 different levels of certification and only the highest have the bandwidth to carry a 2160p, 60fps, 10 bit, 4:4:4 signal. And as far as I can tell, they are all passive so your source or sink can't warn you that your cable isn't compatible. You'll just get artifacts.
The AmazonBasics cable will do 18Gbps, so it can do 2160p, 60fps, 10 bit, but only with chroma subsampling (which is fine because most video sources have chroma subsampling). The Amazon cable may work with a 4:4:4 signal, but it's not certified for it. There's a level above that for 48Gbps cables.
I totally agree with the general idea, though. As long as a cable for a digital signal meets the specifications set by the standards body, you're good.
- walrus01 8y agoOkay, so the last time I bought hdmi cables I got 2.0 rated. Just looked and HDMI 2.1 rated 48Gbps cables are $25-35 each for 6 foot. That's not totally unreasonable. Now how is a $350 cable or a $800 cable any better?
