Question

I have a sharp aquos 92 series hdtv and a dell latitude d630. I have a DVI to VGA cable, and connected the vga to my computer and the DVI to the tv and now what do i do?

Answer 1

now put your laptop in dual display mode by pressing fn+F4 key and see your hdtv is showing what laptop is showing or not.............it has to show.

by the way pressing the keys again will make laptop to go to  no screen mode and again pressing means it will go to single screen (Laptop) mode.
