Does anyone know how to adjust the screen saver settings to make the 3 boxes fill up my entire tv screen?  They seem to "bounce" about an inch to two inches before they hit the edge and I am concerned about burn in.

 Thanks for the help!
 

Anyone have any advice on where to start on fixing this problem?

 

Thanks!

Can you turn off the TV when you are not watching it?  That would seem to be the most effective way of avoiding unnecessary aging of the screen...
