OT:
Sadly, it's getting damned hard to find 1920x1200 even in full-blown monitors, let alone laptop panels. I'm holding onto my BenQ FP241W monitor for dear life since it has that resolution and is an MVA technology. (The reason 24"+ monitors got so cheap suddenly is everyone's been using low-quality TN screens with horrible viewing angles, but I digress...) Barring being able to find a current-gen laptop with 1920x1200, your next best bet might be trying to see if any of the panel manufacturers still make screens at that resolution which you could buy separately. You could get it installed to replace a stock 1080p one.
