So i have a 35ft Kanto installer series hdmi cable
its 24 awg and supposedly 1080p capable

i hooked up an xbox 360 to a 42" 720p tv using that cable and compared it to cheap 6 ft cable i picked up for $10

now the problem is that the 35footer seems to have more jagged edges and what looks like a little artifacting or static. not too noticeable but once its on a 110ish projection screen im sure it will get annoying.

going from a 720p 42" to a 100+ 1080p will only amplify what im seeing right?

is this the case will all hdmi cables as i understand at long distances some loss is inevitable since im comparing a 35ft cable to a 6ft cable.

im thinking on buying a 35ft monster cable just to compare it with mine and then returning it.

any ideas?

What do you mean? Do you actually see serious snow and noise issues, particularly in dark areas of the picture?

HDMI is fairly all or nothing, if there is a cabling problem you will get no picture, severe snow and lines, or very rarely, minor sparklies (hard to hit that sweetspot where things are juuuuust sort of over the cliff but only just beginning to cause problems.)

No. The picture doesn't get progressively worse like analog at distance. It will continue to be perfect just until there starts to be signaling issues, in which case you'll begin to see noise (pause the image and you'll know it's not source/content noise because the sparklies will still be there), and then very quickly beyond that you'll get very severe snow, total snow, or no picture at all. If the image is clean and no noise, you're getting everything just fine, 100%. If you have no picture of obvious noise, then you have a problem. It's kind of all or nothing, that in-between zone is very small.

Thanks for the clarification chris.

Turns out my friends tv has a messed up hdmi port. Even the short cable has weird things happening.

Tried again today and the cable works fine. :D
