|
|
I posted this in the HD Fury forum but have not gotten a reply. I currently run 50 feet of diy rgbhv cable from my rack to the projector. It is driven by a NEC ISS 6010 switcher and works well. I will soon be replacing all my source equipment and they will all have HDMI connectors. I plan on replacing my older Yamaha receiver with a Pioneer Elite VSX-94TXH receiver which will supply all the HDMI switching. I'd like to pull out all the old DIY cable and run one 50 foot HDMI cable direct to the HD Fury connected to the back of my projector using the factory provided external power supply. Will this work OK or is 50 feet to much.

I think as long as you are using the power supply and the run from the fury to the pj is with the very short cable they supply then the only thing that might be a problem is if the 50 footer is poor quality. if it is a good hdmi cable you should not have any problem. I'm running the same setup with a cheap 25 footer and it works great.

OK, so who makes high quality HDMI cable? I've been in analog land to long. The last time I had a question about a digital cable it was for audio  Being that it's digital wouldn't it simply work.....or not?

I noticed today at AV123.com under the accessories area that they have a powered hdmi extender.

I'm using a 35-foot HDMI cable supplied by Ethereal and I've experienced no problems at all. It looks the part, too...larger diameter than most, good heavy connectors...I'm quite pleased.

50 feet is well over the HDMI spec max length. We have a local guy with a G90 and a 45' run. First he used a high quality cable. Then a 25' and a 20' cable with a booster, then a fiber optic. With each change, the picture improved.
Why do you want to replace the RGBHV run which is more robust over long distances? Why not just put the fury by the equipement and send it through an extron or kimcoder to drive the run? I've had good success with this approach as have many others such as Kal.

I don't have a problem staying with RGBHV other then I home brewed them with crude tools. The Fury can screw right on a VGA input port right on my ISS 6010. I just thought the signal might be a bit cleaner if it stayed digital all the way to the projector. I have been thinking of replacing my diy cables with better ones though if the 50 foot HDMI run won't work.

Hmm, is Wikipedia wrong on this front? They are telling people the HDMI specification does not include maximum cable length. BTW, I found (acquired) a copy of the specification (1.3) and couldn't find anything as reference in it on the subject in a brief scan. And since DVI is only a small subset of the HDMI spec one cannot go by that either.

Gee, I will strive to use more accurate terms. HDMI spec does not have a max length since the max length is bandwidth dependent. They have "certification" for cables. There are no certified 50' cables. Read this:
