Spoiler REFERENCE :

So, are there any potential issues when gaming (games use 4:3 aspect ratio) on the native WUXGA display systems (namely laptops)... or, please tell me the software/hardware is smart enough to just leave black space at the flanks (L & R) of the screen. In this example, let's presume the game is running in 1600x1200.
No resizing necessary, right? The 1600x1200 is nice and centered on the 1920x1200, with all pixels (for the game) in perfect use, with some black space on the sides. And please - certainly no... *gasp* stretching.
Please tell me that's how it works.
