HDMI-HDMI cable length

Solution 1:

According to these Gizmodo articles (The truth about Monster cable, Part I, Part II & Part III), for a short 2m run practically any cable will do, but for 10m runs to 1080p you might run into problems with lower quality cables. They suggest trying a cheap cable to start with and if you have problems look for a certified HDMI 1.3a "Highspeed" cable.

The Monoprice 35ft ($35.17) and 50ft ($53.64) cables they tried both failed the 1080p lab tests though the 35ft cable passed the real-world test when connected to a TV (rather than a signal analyzer), possibly due to error correction built in to the TV. So that cable might be a good one to try.

Solution 2:

I just installed a hdmi cable over a distance of 20 meters. At first I bought the cheapest 20m cable I could find -> 50€. Somehow it didn't really work. It worked for my tv, but not for my work lcd (which was the primary target). I then bought a cable for 100€ (again 20m) and that one is high speed certified (whatever that means) and has a build in repeater. The second cable worked just fine. It can transmit sound and video in full hd resolution - can't test any higher resolution.

I have a similar experience with dvi cable. Which tough me one thing: If in doubt, buy a reasonable cheap cable. Non cable is worth a fortune, but the cheapest one never works.

Solution 3:

There is no definitive max length specified in the HDMI specification. I'm using a 5m cable myself to transmit 720p without issue.

There's usually not any difference in quality between cheap and expensive cables. I would go for the cheapest cable I can find at the length you want.

Solution 4:

I recall a study where cable quality only matter when the length is insane, like 50m+. Sadly, I can't find the study/review right now.

If I were you I wouldn't be worried and I'd run right over to monoprice.com
