i have a used dell laptop c640 that is giving me display problems. During boot the display for the bios is one quarter the size of the screen, the whole picture is there but small fonts and display. In the bios i could'nt find an adjustment for video at all. I reinstalled XP and all through the installation the screen size was small. After it installed i could adjust the resolution to fit the screen, Now the screen is full size but the colors seem off, the icons are sharp and the fonts are good but the display somehow is bad. Does anyone know why the initial boot is small cause i think this is the root of my problem. i have flashed the bios but still have the same problem.
