Long Distance HDMI cable causes quality degrade?

[albasbal]

I have heard mixed things about hooking up a projector with a long 40’+ HDMI cable that is will degrade the picture quality. I have recently spoke to a sales rep at my local HT store and he told me that since the cable is a digital cable the signal will not degrade at all. “The 1’s and 0’s on one end will be the same on the other”.

Is there any truth to this?

Well, longer cables do degrade the signal, even the digital ones. Best to get a cable with the largest gauge wires in them, 22ga at least. Some are advertised here or check monoprice on line and look for ga specification.

The picture will either get there or it won't. A degraded signal will mean no picture at all.

I am running a 35 ft HDMI cable that I bought from blue Jeans cable. Not one issue do I have. You also will not beat their price.

High Quality HDMI Cables

I have a 7.5 meter cable from DVI Gear. My previous cable was from Monoprice. The difference in construction quality is very evident. The DVI Gear cable is a beast. I didn't notice any difference in video quality, but 7.5 meters isn't very long. I would assume a degradation in signal would be a partial/complete loss of signal or picture.

DVI Gear offers some VERY high quality cables. They offer their SHR HDMI cables up to 15 meters (though they say they will offer longer lengths). For very long runs they offer a fiber optic system. If you're worried about the signal, buy one of their cables. They use 22AWG silver plated copper wires in their SHR HDMI cables and heavy duty connectors.

To use HDMI at long distances,

You do need a very good cable! The bandwidth for digital is higher than analog and will attenuate faster with longer cables. John

...and Bluejeans cables state that you are ok within 50ft. After that you should use an inline signal booster.

I just bought a couple of cables from Blue Jeans (15' and 6') and they are very nice and reasonably priced. I originally had Monoprice cables in the same length and found that the 15' worked OK when hooked directly to the TV, but introduced some sparkles when going from the DVD to the receiver, then to the TV. These were the 28 awg with ferrites.

Hello,

Check out our day one EHX coverage. Impact Acoustics will be introducing their new Digital Rapid Run. When I spoke with the manufacture they indicated that the system has been tested at 60ft at 1080p resolutions with no signal degradation. BTW you can get signal sync and degradation with HDMI. We have tested long cables that produced an image but had timing issues, sparkles and resolution choke points.

Ever heard of artifacts?
