Cables, especially ones of high-quality like the ones Cable Matters sells should not simply go bad, as long as you treat them well. There is nothing about a cable which inherently means it will break down. ... The reason cables like HDMI are so durable is because they are designed to be.
How do I know if my HDMI cable is bad?
Common problems that may be signs or symptoms of a bad HDMI cable include:

How long should an HDMI cable last?
Like many audio, video, and data cables, HDMI cords can suffer from signal degradation at longer lengths—50 feet is generally considered the maximum reliable length. And it's rare to see an HDMI cable longer than 25 feet in a store.
