There are extreme cases where you get no signal but if the monitor is revealing enough on a high res signal you might get a compromised signal. There are lots of 50’ cables out there but not everyone is certified to deliver 4K or 8K resolution in that length. Mono Cables and others decent manufacturers out there will only even offer longer lengths in certain models if they can guarantee it will pass a full res signal that far without issues.
Again, shorter lengths you won’t see these differences typically.
Sure, but to clarify, it's not a continual degradation... it's either getting a signal or not, for the most part. It not like there's a low, medium, and high options with a sliding scale of picture quality, like there could be with speaker cables.
