HDMI cable - How long?

Should be getting a projector soon, which will cause me to need a long HDMI cable. What is the longest I can go before I start having problems?

You won't have any issues up to at least 50 ft. with a digital cable. Probably even more.

You may want to start thinking about going to a larger gauge wire as the length increases. Possible something like 22AWG or so.

Other than that it won't be a problem.

Thanks for the help. I had read that longer runs can cause a problem with video dropout. Some places recommended things called a restorer, extender, etc to enhance the signal. Are these just gimmicks or only useful on really long runs?

Also - my processor has an option for 'HDMI Repeater' in the video section. Would this help, or is this for something else?

Thanks again.

The cool thing about digital is that weak signals dont hurt the picture. A weak 1 is still a 1. A fuzzy 0 is still a 0.

They're not gimmicks but from what I've seen 35 ft shorter on dvi or hdmi no issues at all, and like he mentioned I've seen few people with 50 ft say no problem but that depends on the device.

Yep the better cords lower the AWG(gauge) meaning thicker wire for longer run.
Heres the place most people like I use them or pccables.com both quality product for decent prices.

If you look around monoprice, some of the longer runs of smaller wire suggest a repeater or equalizer. The 22 AWG does not. You have the option of silver plating if you want to spend a bit more.

I don't really think the processor as a repeater would really do anything, since the run to your projector will still be 50'.

It is the run from the processor to the projector that will be long.

Right, you would want the repeater in the middle of a long run. I think in the beginning isn't much of a benefit. It could increase the signal in the line, but I think with a quality cable it shouldn't matter.
