Not too long HDMI cable issues

I think you are barking up the wrong tree. If the cable works before you run it behind drywall, then it should work afterwards too. There is something going on. See if you are putting it through tight bends that are kinking it. There could also be interference like from a power wire running in parallel with the HDMI. That should cause noise, not a blank screen. Also, it could be a really stupid mistake like setting something up wrong. Check the input on the projector to make sure you are using the right one. Sounds dumb but silly things can mess you up and it's hard for us to diagnose this over the Internet.

Why spend so much money on cables? Monoprice is a lot cheaper. I have a 35ft and a 30ft run near power wires without a single issue. Are any of your cables run parallel with wiring?

WAY too much. HDMI of that length is about $15 on amazon.com (and any other reasonable e-tailer). Decent build quality, too.

HDMI is the latest version of the Monster Cable speaker cable scam. There's nothing magic about it, other than it's ability to generate obscene profits.


As for your failure mode, the posts above are on target.

Jeez guys, how about toning down the personal crusade against over priced cables and taking a bit of effort to help the guy with his problem?

To the OP, I have an AE3000u and a Denon AVR connected with a 35' HDMI cable (a 22AWG Monoprice cable) and I have been fighting issues with the connection too. I can get the signal to pass, but it will drop out randomly and sometimes be almost impossible to keep locked on. Some nights I would spend dinking with the cables and never be able to get a singal to come through on the PJ.

I wouldn't worry that the Denon AVR isn't powerful enough to send the signal that far, mine does it just fine when the stupid connectors are seated properly. (Do make sure that you do not have a large section of the HDMI cable coiled around into a pile. If the cable is all coiled up on itself, then the signal will likely not get through.)

First and foremost, HDMI connectors are a crap design. Most times, it is not too bad to cause problems, but when you get one of these 22AWG in-wall rated cables, they tend to be very thick and heavy. It is very difficult to get the connectors to make proper contact unless your cables feed to your components just right so that there is no strain on the connection.

Before buying anything further, I would test just to make sure your AVRs HDMI circuit isn't hosed. If you have a monitor with an HDMI input handy, put it next to your AVR and hook the two together with a short, lighter weight cable to make sure your AVR is passing the signal.

If that works, then start dinking with the connectors. If possible, strain relieve the cable coming into both components. There are adaptors you can get that are built specifically for this. I've bought a couple of these:

The articulating adaptor helped some, the 8 port saver cable really helped a lot, but still hasn't completely eliminated the dropouts. I can wiggle one of the terminations on the 35' monoprice cable and make the signal come in and out. But it is still far from what I would call a robust connection.

I have a 20-25 foot cable installed in the wall. Can not recall where I purchased the cable. I have had similar problems. Cable feeds a Mitsu projector. All examples are fed with 720p. With input from Directv HD DVR I see no problems. With input from a popcorn hour there is red splotchy noise in dark scenes. With new Oppo player there is what I would call dropout snow (white noisey areas intermittently on screen). I would guess the combination of driver hardware and my cable are being marginal. I don't mind trying a different cable. I would like to know who has used a 25 foot plus cable with a popcorn hour and an oppo player with success and what brand cable was it.

achi,

If it fixed your problem then thats all that matters.

In the past I have used BlueJeans [longer runs] and Ethereal and they work well.

For the amount of money that we put into these theaters, to get it working right for $200 = priceless. Enjoy.

Wire is bi-directional. Copper doesn't care what direction the electrons are moving. Unless there's an active component in there somewhere, "unidirectional cable" makes no sense.


(There is the case where you prefer to connect a single-ended shield drain to the source component ground, but I don't think that applies to HDMI.)

It would have been an active cable. They can use thinner wire (cheaper) and then add an equalizer to compensate.

We import and sell HDMI cables (thousands of).

For runs upto :-

15m (50 ish feet) we use 26 AWG
20m (65 ish feet) we use 24AWG

These will pass 1080p/60 without any help.

We can goto to 40m (133 ish feet) on 24 AWG if we only require 1080i/720p.

A thicker cable does not mean higher performance. It may, but since this is digital it pretty much works 100% or not at all.

The OP had a 22awg cable which should have been more than up to the task, but as it wasn't it would suggest either a faulty wire (unlikely) or a faulty connection (bad solder joint).

As an aside, the majority of Chinese manufacturers won't even offer 22AWG as a standard option. It has to be ordered to your spec. Why ?? Higher costs / no real performance gain and a stiff bulky cable that doesn't want to stay seated in the HDMI socket.
