Hi, Just bought a Sony LCD HDTV, however when I watch I see a lot of grain. The TV is connected to a HD cable box from comcast. it's fine with HD channels but on normal channels, the picture looks grainy, also what is this HDMI? I was reading the manual and it's supposed to be connected to my TV but comcast didn't put it
thnks in advance

Yes the cause is because in normal channel the information is not enough, it's like to stretch a picture so it can fit to your screen. It's best to use HD signal, and this thing only look obvious in large screen TV usually over 40" the bigger the worst. HDMI (High Definition Multimedia Interface) is a digital connector which contain digital information for Video and Audio, it's the most advanced connector that use in TV now days. You can find this on PS3, New DVD player, HD-DVD player, BD player.

The graininess is the noise that is present in all analog signals. The amount will vary depending on the source. Your new TV has a high enough resolution to reveal more of that noise than a poorer resolution tube TV. The only way to avoid this is to go digital. If it is offered, get digital cable from comcast. Eventually all broadcast TV will be digital, and perhaps cable will switch to all digital also. Satellite TV is all digital.

buy an hdmi cable, it carries the best signal.
I also bought a sony lcd hdtv, but still waiting for the backordered hd dvr from directv. Right now it looks like crap, i don't even have component cables, so i'm just using an anolog signal into a hdtv, it's horrible.
Point is: I believe most non hd channels will look like crap on your tv.

I even have certainly experienced this... i will anticipate there isn't something incorrect which include your television. you have not yet experienced your television in digital / HD mode as you observed at Cosco. Sony television's are waiting to view channels, even though in the event that they don't convert them to digital or HD photos without cable card or a digital cable container. attempt a DVD on your television. If the image nonetheless sucks, then its the television. yet maximum possibly it would be a great image. If the image is large, call your cable corporation and get a digital cable container or a cable card. stable luck!

Ok on the new HDTV's on a regular signal the tv picture sucks becasue the tv isnt meant for that signal so it wont process it properly.
