Adding a Monitor for a 9300 that doesn't support 1920x1200.

[MowrMowr]

You cannot get your 9300 to function at 1920 x 1200 unless you bought the WUXGA screen. The video card can handle that resolution (meaning if you plugged a 2001FP into it, it could run at 1600 x 1200), but the screen you have there cannot handle it. You can buy a WUXGA version of just the screen portion (i.e. the lid of the laptop) off eBay or something similar if you can find one then just swap out yours for the new one. Might be cheaper to just get a new laptop though.
