I am trying to replace a Gateway FX Laptop screen.  the new one is a 1400 x 1200 screen it is off an identical laptop as the one that needs replacing.  The have identical video cards but the one I want to upgrade only shows support for the screen presently on it ( 1400 x 900). What will I need to do to be able to utilize the new screen at 1400 x 1200 ?
