Extended length HDMI cables

post #1 of 6
Thread Starter 
So HDMI cable is "rated" to send 1080p only up to 25ft. If running longer, say 30ft, WITHOUT a extender or other device in between, is it still possible to achieve 1080p?

Yes. Once you start hitting 50 feet the signal is not as good. I know places like blue jeans cable sell longer cables that don't have to have an extender

The HDMI spec, in fact, gives no explicit length limit, but the requirements of the spec implicitly give rise to some length limitations for "compliant" cables. A cable isn't permitted to degrade the signal past a certain point--that point is a bit hard to put one's finger on, because a cable is deemed spec compliant if it meets either of two tests: an "eye-pattern" test which measures the overall shape of the HDMI waveform at the cable output, or a set of parametric tests which measure the attenuation and other losses in the signal.



Basically, a signal begins be degraded by noise immediately. Better quality cables introduce less noise and provide better shielding.

I picked up a 50 ft hdmi cable from newegg (link depot brand) for application in our conference room to connect an overhead projector to an under the table PC ... getting 1080p no problem.

The cable i speak of was less than a dollar a foot... completely wiroth the money.

Well i bought the cheapest 35ft cable I could find, $10 shipped from ebay, and it works flawlessly. Compared it to shorter higher quality cables and picture is same. thumb.gif
