Don't be duped into paying too much!, August 17, 2005
This review is from: Monster Cable M1000DV HDMI to DVI Cable, 2 Meters (123165) (Electronics)
There is no need to buy such an overpriced cable. They are making a fortune off of marketing and making you think you need such a cable. Just get a generic that costs 1/8th the price. You won't notice a difference.

You Decide, August 20, 2006
This review is from: Monster Cable M1000DV HDMI to DVI Cable, 2 Meters (123165) (Electronics)
I wrote this review simply to correct the individual who wrote "Digital cables either transmit the bits or not." Uh... not quite ... it might surprise you, but there is science behind this stuff. That is why certain cable companies - not just Monster, mind you - charge more than $20 for a cable. If interested, read on.
"Digital" refers to an encoding technique where a signals are composed of a stream of high and low logic levels (0 = low and 1 = high). People who haven't studied microprocessors like to stop there and say "heck, any cable can transmit 0's and 1's! Why should I pay more?" What they don't understand, however, is what constitues a 0 or a 1 or how these signals are interpreted by a modern microprocessor.
Without going too heavy into this ... most people have heard of logic "gates" (transistors) - extremely large clusters of transistor form the backbone of CPUs, etc. Just as it takes energy for you to open a door, these "gates" are "opened" and "closed" by energy, and it comes in the form of voltage. Bare with me...
"Noise" is impossible to completely eliminate in any circuit. As a result, logic high (the digital "1") has a certain threshold that must be met in order to "open" the logic gate - this prevents noise from corrupting the signal and injecting false positives. What does this mean?
Well, it means that a certain level of voltage must be present for a microprocessor to detect that there has been a transition from logic low (approx. 0 volts) to logic high (above the threshold voltage). -----MAJOR----- This is where the non-initiated are mistaken!! Digital is NOT simply a finite 0 or a finite 1, at least not during tranmission. There are transients (i.e. time where the voltage increases and falls) during transmission.
A good cable will A) shield the main conducting wire from more noise and B) have less impedence which will, in turn, make the transients more true - 0's and 1's on the source side will correlate better to the 0's and 1's on the receiving side. This will maintain the fidelity of your signal and allow your digital stream of 0's and 1's to sound and look nice.
Over short lenghts, you'll have to decide if there is a difference. For long lenghts, you might be surprised. HDMI traditionally tops out at 5m. Anyhow, as the title says, You Decide.
