Do you need any special type of HDMI cable to connect from a High definition Digital Satellite Receiver to the TV? or is a stock standard one ok

cobber,
"Under five metre an HDMI cable made correctly cannot introduce any degradation to picture and sound quality,"
quote taken from:

Don't get sucked in with information that suggests that a more expensive HDMI cable will give a better signal quality. They transmit digital data, not analogue, so better copper does not equal better picture. The only reason you might need a higher grade cable is if you're using HD above 1080p, which I doubt that most people do with a standard HD sat receiver (even then, your cheap cable will probably work fine).
The only reason that you may want to spend a few more $$'s is to get a cable with better quality connectors. Some of the cheaper cables have cheap, fragile connectors that break with the slightest strain. Make sure you get one with a fully molded connector, rather than one made with two plastic halves glued together.
My experience is 15 years as a tv/video technician + professional engineer (electronics & computer).

Absolutely right, it's digital - either it gets there, or it doesn't.
The ONLY WAY that a poor quality cable (or fibreoptic, or air) can 'degrade' any digital signal (other than total or intermittent failure) is if the equipment is designed to detect the available bandwidth and negotiate a lower signal format accordingly. Your TV and DVD don't do this.

Geez Guys, you really have me scratching my head now.........
I bought a Sat TV setup recently with the Altech Vast system. I tried to set it up at
home using an HDMI connection from the decoder to the TV.
I could not get it to work, so I rang Vast and they firstup asked if I was using an HDMI cable, and then advised me to disconnect the HDMI and use the composite connectors, and it worked immediately.
I asked the person I spoke to why? but they refused to discuss this further.
I received all channels OK and the picture looked good, so I packed it all away ready for an upcoming trip.......
Has anyone else had this problem?
Cheers, Dalb

I have used both a AV connection am a HDMI on a Altech Vast System and they both work - you need a HDMI for good quality HD

If the system is still new go to your supplier and ask for him to fix it.

My guess would be an output or input menu selection

Thanks for your help Guys.....
I am still working on the problem.
The first HDMI cable does not work at all. The second one I tried works sometimes and not others.
I am reluctant to purchase yet another cable but I guess I will have to, as Access, the WA supplier, said that because it works the problem is not the decoder.
