The refresh rate should be 60Hz also and the resolution should be approx. 1024x768. Give that a try and see how it goes.
I just bought JVC's 46" LCD TV, model # LT-46FN97
The manual says to set the resolution to 1024 x 768 and refresh rate to 60 Hz. I did this, and continued to hook up the PC to the TV's VGA input. However, all I get is the screen with squiggly lines. Any other ideas on what the problem could be?
