Laptop Resolutions are Set by the LCD used. As an example my IBM ThinkPad 31P is set to 1400 x something. If i reduce the Resoltuion to 800 x 600 than the screen looks Fuzzy Anti-Aliased, because the LCD is not designed for that resolution. I hope I'M making it clear. Laptop LCD's have a maximum resolution that they are set too anything lower looks bad. Now for Contrast, usualy its a combination of FUNCTION Key (FN) plus some symbols that look like Brightness / Contrast like on your PC Monitor.
