Gain signal rumor...

[Geoduck]

Just to verify a rumor.

According to a friend, some flat screen TV's have particularly strong gain signals that cause screen distortions when viewing from external devices (DVD players, game consoles, VCR's, etc.) Whenever he enters a save menu of a game, or when a dialog box appears on the screen, the right side of the box was slanted--I saw it myself.

He took the TV to a servicing center, and the technician said it had to do with the TV's strong gain signal, that there was nothing he could do to fix it. Supposedly, this was a common problem with 50 hrtz flat screen TV's, but not with 100 hrtz TV's.

This news came just in time, since I was about to buy one myself.

In short, was the technician speaking out of his hiney, or is there really such a thing (gain signal issue?) If so, how can I avoid buying one of these wonky flat screen TV's?

FYI, the one I was planning to get is a 21" Phillips 21PT3324/69S (anyone using one of these?)

Thanks!
