things have taken a turn for the worse.

well, here's a grim development.

everything worked fine for a while...but now things have gone awry.

the display on my tv...still seems to recieve what my computer's telling it...but the left and right edges are no longer straight vertical lines. Instead they sortof bulge and curve in (not by very much, mind you, but even the say, quarter of an inch on each side bothers me). The display on my pb is still perfectly normal...and i haven't changed anything...but, still, the display on the tv has edges that aren't as they should be.
does anyone know what the hell is going on?

thanks for the help, guys. *crosses fingers*

hm. this wasn't where i planned to post this at all. i'm sure i didn't mean for this to be a new thread. sorry.
