differences in displays

First off, please don't crosspost.

TrueLife is just a glossy finish over the screen. I think UltraSharp is just referring to the WUXGA display.
WXGA, WSXGA, and WUXGA are resolutions. WXGA is 1280x800, WSXGA is 1680x10??, and WUXGA is 1920x1200

To see the difference between resolutions, see if there is either a Dell kiosk in a nearby mall or go over to your local B&M electronics store and take a look at the notebooks they have to get a feel for different resolutions.

Integrated intel graphics = ABSOLUTELY NO GAMING.

If you want to play games, the MR X1400 is the lowest card you should pick, and realistically, you should go for the 7900GS if you can.

Thank you for the information.

if I undrstand this correctly then

Truelife is just the glossy finish, nothing to do w/ resolution

Ultra Sharp has better resolution that the standard XGA

 

Yes, that is correct. True Life is the glossy display. Ultra sharp is more of a marketing term. The thing to focus on with resolution is whether it say WXGA+ (1400 x 900 in a 17" panel) or WUXGA. WUXGA is the higher resolution, which you may or may not have trouble reading since the text size will be smaller.
