like 2 months ago i had this option enabled that didn't let my fullscreen modes scale to my full res (1440x900).
when i went fullscreen the window was just moved to the upper-left corner of the screen and the borders disappeared. sorta like this:

without the borders. this was fullscreen mode.
the thing is, somehow the settings got mixed up and the scaling is now enabled. so the image stretches to fill out all the screen, making the graphics horrible.

i heard there is an option on NVIDIA Control Panel that lets you uncheck the scaling options.
i tried going in nvidia control panel, but the driver doesn't recognize my monitor as a LCD, but as a CRT, so i can't uncheck the scaling options under Display (scaling options are not even shown). any ideas on how do i get my graphic card to detect my lcd, if not, is there any other way to disable fullscreen scaling?
specs:
Windows XP, 1GB RAM, NVIDIA 6200 graphic card (latest driver), LG Flatron L192WS monitor.
