Recently I got a new 65" TV, but the PC input only goes to 1280x728 or something along those lines, so I had to scramble to get a dvi to hdmi converter. I bought hdmi to dvi converter that was monster brand(that was all I could find) and used the monster hdmi cable from my projector(that I bought for a couple bucks at flea market in package:P) About the same time I ordered one of the ebay cheapy cable that is DVI to HDMI. I had been using the monster cables for 3-4 days when the other showed up. I hooked it up and I can't tell the difference. I know the monster cables are thicker, and they could potentially last longer. Is there any possible reason for me to keep the monster adapter as opposed to the cheapy ebay cable?

If you aren't getting sparkles or worse, the picture is as good as it is going to get.

FWIW if you bought a Monster cable in the package at a flea market it is probably counterfeit.

It wasn't an entire table of monster cables, it was a single one in a beat up package on someones table.

Being digital if it works it pretty much works, right? I was looking at some tests of different cables on a plasma using a analyzer and it showed that there was no difference between cables in the realm of picture quality. They just aren't like audio cables I take it. I also took note that there really isn't anything that interferes with HDMI cables as it is a digital signal and not coax.

There are many environment conditions that can interfere with a digital cables, which include HDMI cables. Electrical noise is one of those. In this forum we mostly hear about using too long of a cable and having the digital waveform become "rounded". However, in all of these case you'll know you have a problem if it were to happen. The effects on the pcture are not subtle as Colm said.

These are not like analog cables. These are just transmitting the electrical equivalents of 1s and 0s, but at a very fast rate.

The sparkles would be ones that didn't transfer correctly? The TV's automatically fill in and fix missing information, right?

That's incorrect. There is no error correction for video and audio with HDMI. The sparkles are the results of the bits in error.

All cables transmit voltage/current. This can represent the output of an analog transducer, or it can represent two distinct states (digital) in both cases, the signal on the conductor is 'analog'.

Any conductor can have induced interference, it depends on the receiving circuit to get rid of the noise.
Your comparisons between 'audio' cables, HDMI and coax are not correct.
