I have a new 27" Samsung HDTV Monitor (HD Ready). When playing from my digital cable connection, it sometimes acts weird. First, it seems to degauss like when you turn it on or off, but it also does it while the TV is on. Like right at the start of a commercial break when the show ends and the screen goes black before the start of the first commercial, the screen sometimes degausses. Also, sometimes, at seemingly random times, a display pops up on the screen in front of the picture and says my sound source. It will say "Sound: Sterio", stay for a few seconds and leave, then another will pop up and say "Sound: Speakers + SAP". It always does these two in a row. I don't know what either of these mean. I've never seen it doing this when I play games, it only seems to do it when playing from the coaxial input. I've never had an HDTV before, so I really wouldn't know what is normal or not, I just know I never got anything like this on my old normal TV.
