has anyone tried running HDMI over a long distance?

I was wanting to possibly make a HTPC, but I figure why not just run a 30-50 foot HDMI cable and get a video card that will work with it to connect to my tv.

Shouldn't be a problem provided you get a HDMI cable with a sufficiently large AWG for that distance.

You have to be very particular with cable at that length. Some will work with 1080i or 1080p24 but fail at 1080p60. Make sure you test the latter before finalizing. You'll need at least 24AWG, maybe 22.

I run a 35 foot cable from my projector to my equipment, and it's from Monoprice.

Two things to be aware:

1. As stated above, the more data going through the wire, the higher the chances it will have issues (sending a dvd - 480p - signal may be successful where 1080p high def may not).

2. Devices are not all created equal. Some players/projecters/hdmi switchers, etc. can be very finicky, and others will handle everything you throw at it. The HDMI standard seems to be getting much better, but I have experienced a lot of frustration with certain devices. Just because you know someone who ran a 50 foot cable successfully doesn't mean your equipment will do so without issues.

doesn't large awg mean thinner cable?
or do i have it backwards?

in any event, i'm running a 25 footer from my pc to tv without problems.

Yeah AWG is one of those odd measurements where the smaller the number the larger the wire. 1 AWG is really big where as 28AWG is really small.


If you are running a HDMI cable a long way try to not bundle it with power cables and also try not to coil the cable up as it can cause reflections.

AWG is essentially how many times the wire can be wrapped around some standard measuring barrel - so smaller AWG means thicker wire.

so wouldn't you want a smaller awg for more shielding and signal loss?

I was just asking if anyone had used it, but you can do HDMI over cat5.

Link

You can do 1080p up to 130ft. Especially easy to do if your house is newer and has pre-run cat5.

Smaller awg would give less signal loss , shielding is independent of the wire gauge that is up to the manufacturer.

so why did purdey recommend a large awg for greater distance?

Lower gauge = thicker wire. The longer the run, the thicker you will need to successfully transmit the signal.
