HDMI Cable

The other day I was looking for a HDMI cable to connect a laptop and a monitor. Although the standard has been there for years already, I never had to actually buy a cable before, therefore I didn’t know anything about it.

Turns out, there are a lot of expensive scam (like with Ethernet cable category): a HDMI cable eieither work or it does not. More expensive mostly doesn’t correlate with better quality 1 .

The fact is, HDMI is digital, meaning you either get the feed or you don’t. High prices and gimmicks like gold-plating don’t affect 1s and 0s.

As shown by this picture 2 , it’s pretty clear when a HDMI cable is faulty:

Basically, the main (and shall I say only) factor for choosing a HDMI cable is its length: longer means more attenuation of the signal. This is true above 7.5 meters. In that case a more expensive cable may be worth it 3 :.

The next criteria is personal preference: I found out that nylon braided cables are a huge improvement and are much sturdier than the standard rubber or plastic material used in most cables. Fortunately they aren’t even more expensive than their plastic counterpart.

“Mostly” because some more expensive cable are still a good investment under some circumstances.
In that case I’d probably go with Blue Jeans Cable which proved itself to be a reliable and trustworthy company.
