Truth on HDMI

Lots of HDMI cables are made to such poor tolerances that simply changing the distance between one of the conductors and the insulation will have a demonstrable impact on performance.

Yes, but that's *during* the bending (this "loss of quality" is due to lost frames, maybe a dropped keyframe in the signal while bending it). The "performance" will be either 1080p or nothing once you're done moving it, and I don't shake the cables while watching TV.

You can pay for a good cable construction (say, the difference between 12$ and 25$ for a 4-foot), but gold plating or EM insulating don't have any "noise" between 0s and 1s to shield the cables from.

I bought a 6 foot HDMI cable on Invalid Link Removed
I paid more for shipping than the cable and the cable works perfectly.

Screw Monster....and all their lawsuits against anyone that even thinks of putting the word "monster" in their name.

Thank you so much. I would never have worked this out for myself without your help, I'm way too old to understand basic differences between analogue and digital signals as clearly as all you clever younger folks do. I'm sure our black and Asian members here will find this equally useful.

:D Yeah, those of us who took courses in transmission line theory and digital electronics back in the 60s are so behind the times.

Yet, I've had problems with some of the cheap HDMI cables I've purchased. Still, never paid more than $10 to get a good one and picked up a bunch cheaply from Dayton Audio when I had to replace the tweeter in my Schroeder 1212r and they work fine.

I don't have a citation for you, except to recall mainstream digital signal transmission theory. The big difference between analog and digital signal transmission is a feature called "noise immunity."

With analog transmission, small amounts of noise, or small amounts of loss, are directly converted into proportionate amounts of noise or loss in the final reconstruction of the input signal (e.g., the sound coming out of a speaker). You hope that the noise and loss remain below a reasonable threshold of audibility (or visibility for video, I suppose).

With digital transmission, noise and loss have no effect on the reconstructed analog signal until they cross a threshold. In a well designed system, the signal is transmitted with considerable headroom above the threshold. This is why digital transmission can be noiseless and lossless.

Transmission standards such as HDMI and Cat-5 impose requirements on the properties of the cable, which can be compromised if the cable is damaged.

It's a bit more complicated for some forms of extremely high density storage or high bandwidth comms, where some level of errors are tolerated, so long as they are correctable at the receiving end. For systems that need absolute 100% error free recovery, such as a USB hard disk drive, a combination of lossless transmission and error correction -- perhaps even with redundancy -- is employed.

A 250 dollar HDMI cable is rediculous. But I do like my Monster instrument cable, with the lifetime warranty I've had replaced about 3 times already.

The cheap "Live Wire" cables that Guitar Center sells come with a lifetime warranty, as does the house brand ones that the local mom & pop music store has. A lifetime warranty on cables isn't a big deal. Besides, a decently-built cable that isn't abused should actually last a lifetime

I've never understood the whole 'lifetime warranty' argument from Monster cable defenders. Wouldn't it just be wiser to buy a cable that won't fall apart?

I'm hardly a "Monster defender" -- I think they're one of the most unscrupulous, amoral pieces of feces on the face of the earth -- but fwiw I got a Monster bass cable in 1991 and have proceeded to use it for probably every gig I've ever done since, dragging it around on tour through several countries and a third of the states in the US, and it has never failed. Not once.

I'm kinda pissed; I want to take advantage of my Lifetime Warranty!

A few folks I know make their Monster Cables "fall apart" when they want a new one.
