Laptop screen guide and graphic cards reviews

I am in the process of buying a new laptop and was a bit confused while choosing the screen resolution, specially as Dell do not show pixels resolution but abbreviations like XGA, SXGA, WXGA, WUXGA, ... which don't make any sense.

So I was happy to find this Notebook Screen Guide:

Here is the interesting part:

XGA / 1024x768 / 4:3
SXGA / 1280x1024 / 5:4
SXGA+ / 1400x1050 / 4:3
UXGA / 1600x1200 / 4:3

"Widescreen" Screens
