MacBook 13.3'; changing display settings to default?

i accidentally changed the display settings, so i put it back to the highest resolution (1280 x 800) which im pretty sure was the default, and it looks the same, but in applications like firefox and when i play the sims 2 through VMware Fusion their like half normal size. So if i zoom in once on firefox its fine, but the sims only takes up half the screen, and before i accidentally changed it it took up the whole screen.



so if anyone could help me find out what to do to get it back how it was it would be greatly appreciated, and of course there's the 10 points.

thanks :)MacBook 13.3'; changing display settings to default?
Not sure what the ';default'; is but to change the settings its System prefs%26gt; Displays%26gt; choose your prefered resolution.
