Don't Waste Money on Pricey Cables (Tip of the Day)

No matter what the salesman tells you, don't waste money on pricey HDMI or DVI cables. Unlike analog cables, digital ones pretty much either work or they don't, and unless you're running more than a dozen feet, you'll never see a difference.

Monoprice is good for speaker wire and 1-off stuff. However, HDMI and subwoofeer cables, I prefer BlueJeansCable.com

It does make a difference. I've gotten burned with cheap cables purchased off eBay and they were shorter than 12'. They worked fine at 3' but the 6' cables crapped out on me. I don't believe in spending $100 on an HDMI cable, but sometimes the $29.95 is necessary. And I've learned to stay away from the $5.95 cables.

I gotta agree I just bought 3 6' HDMI cables from MeritLine for $12 delivered and they work perfectly!

Untrue. In fact, it's a myth.
Lower quality cables may have greater attenuation over long distances, which basically means the signal shrinks. If it shrinks enough, pulses may fall below the threshold needed to register a '1' signal.
This is completely untrue. You guys are thinking in the time domain, in which case, signals look like pulses and flat lines between them. In the frequency domain, digital signals are a mass of lots of different sinusoidal (analogue) waves at various frequencies and amplitudes. If the frequency response of the cable does not allow these signal frequencies to pass at lowest attenuation, the whole signal will be screwed.
Digital signals actually require much higher bandwidths as a result of this - it takes a lot more frequencies to make the pulses, leading to signals needing a greater share of spectrum. Also, if cables are being used in a high interference environment and are unshielded, frequency components may suffer interference which causes the signal to be damaged.
Research something called the Fourier transform. This is a complete myth. Digital transmissions are more resilient, but saying the cable makes no difference is just plain wrong.

I should add that the capacitance of the cable is also of high importance, especially with digital transmissions. Digital signals in particular are much more susceptible to slewing.

Digital transmissions have Error Correction built in. If you buy a rated cable that meets the specs set forth by VESA or IEEE - then you will be fine.

Like they say, digital is digital you either get the signal or not. $100 HDMI cables are for suckers. With digital, there's not interference to deal with, phasing, cable quality, etc... Signal is either there or not!

Check out Bluejeanscables I have a 50FT HDMI and it works perfect.

My experience is that you do get what you pay for. I have just bought the following HDMI cable http://www.digitaldirect.co.uk/cyberdyne/hdmi-1m.html . Cheap cables dont have the same quality shielding so may suffer from electrical interference

The problem is - there are no profits in televisions anymore so the sales people try to shove high profit cables and warranties on us. I cant say I blame them in a way, as how is anyone going to make any money on selling the monitors?
As sorry as I feel for them, I bought my tv one place and bought the cables at http://www.multiconnects.com for a fraction of the price. As long as the cables are made well, proper gauge for the length they need to run, and the store guarantees them (multiconnects has a lifetime guarantee on all their cables) then why spend the extra.
I have yet to see the difference on screen between the $400 cables and the ones I just got.
