HDMI Cable Output Problem

DJDAMNAGE 9:19 PM - 2 March, 2010
I recently purchased the mini-DVI adapter to HDMI for my macbook. I had been using vga to run into the projector at my gigs and wanted to upgrade. I just bought a 100 foot HDMI cable with the intentions of using it instead of VGA. Problem is when I tried plugging in to the HDMI port in to my gigs projector (the projector model i'm not sure but I'm assuming its a quality one, its main purpose is for movies at the movie theater where I'm using it) nothing is detected. It has two hdmi ports, a composite, and a vga. I tried both hdmi ports while clicking detecting displays on my mac and still nothing. The VGA input works fine with a 100 foot VGA cable keep in mind. What's really confusing is when I plug in to my home HD LCD TV HDMI port with a 6 foot cable, it works fine. Is the 100 foot hdmi cable too long maybe? I returned the 100ft hdmi cable and am awaiting a 10 meter (30 foot) hdmi cable hoping this may solve the issue. Thanks for your help

I am wondering if the last "detected" display that you had on your mac is set at a higher resolution that the projector can handle. this has happened to me before.

you need to change the 2nd display to something very low resolution then try to plug it into the projector.

one last thing that might work, just plug everything in, then reboot the projector and the laptop with it plugged it. i have had this work too in detecting extra displays (where i have 1 projector and 3 tvs, but the projectors resolution isnt as high as the TVs.)

sup homie. i know we talked about this on the phone but i'd thought i'd post so others can benefit. it's probably the length of the cable. i found an article that explains in more detail.

good luck.

the only reason i didnt suspect the cable length is i have ran a 100ft s-video cable and it worked fine, and thats way lower quality

Nice reference Itchie Fingaz!

Dang man I tried that method you mentioned Hes but no go. Could it be the projector?

Hmm, thats odd? so 2 things you can try:

1 - plug in the projector to the laptop with a different, shorter HDMI cable, see if it works.

2 - use the same HDMI cable that doesnt work on a TV or something else to see if it is detected.

that sucks man, hopefully its just the cable or something.

this is what i use. a bit pricy but see if you could get owner to pay for it. it would be a good investment for their system.

this logic is backwards. a lower quality (less information, lower frequency, simpler signal), will carry longer than a higher quality signal on a cable.

100ft is way longer than you can expect to get reliable HDMI signal on a cable natively. the best way to do this would be with baluns or convert the HDMI to a fiber optic signal or something like that.

even if you do get a 100ft hdmi to work, I wouldn't depend on it.

good to know swift. I'll stick to my VGA for mobile gigs

If you really wanted to run 100 feet of HDMI, the most reliable/inexpensive way to do it would be to use the converters ("baluns", as a-swift mentioned) that send the signal over a pair of CAT6 Ethernet cables.

Not only is the connectivity more reliable, the combination of the two baluns and two runs of CAT6 would probably cost the same or less than 100 feet of high-quality HDMI cable...and the two runs of CAT6 will also be easier to deal with than either HDMI or VGA (thinner, more flexible, easier-to-replace-cheaply cables).

100 feet of VGA may have its own problems. It's an analog connection, and I think with that length you'd be likely to see some picture degradation.

HDMI being digital, you won't see degradation...the image will either be there or not.

I've used baluns for a 100ft run of HD for well over a year, twice a week. It's rock solid, not once having a picture issue.

I just bought a 100ft hdmi wire with "booster" from Amazon and it works fine off of a powered 4 hub hdmi splitter using Serato video mix emergency... Try this out and see if it works for you.. U can buy one for about $65.00

If you read the history of HDMI cable, you will find out it was a hurried up profile and was only good for 100 feet. I found that even adding a 90 degree turn at the wall was enough loss to cause lines and noise into a video picture. I got rid of the 100 foot and put in a 60 foot which was enough and it works just fine. I have been installing HD over coax surveillance system and I find they work as well as IP with a lot less BS with the internet.
