First of all, what's the difference between a normal tube HDTV and a "multimedia/monitor hdtv"? Just the VGA inputs? Anyhow, the problem is something called "drag-lines". Check the link to see what I'm talking about: http://www.geocities.com/josh_qs/index.html If anyone has ANY idea what to do (other than call Zenith, of course), PLEASE let me know. I would appreciated it very much. I've been trying to figure this out for about a month now with no luck. I really like my HDTV, but this anomoly is driving me crazy! Thanks in advance!
