It’s a LCD monitor and there for it is highly recommended that you do NOT change its resolution. This will lead to ugly random pixels around things like text making it near impossible to use the screen. Sony may also have set it so it can only display 1024x768. If its done like that, a driver will not change anything, you'll still be unable to change the res. Unless, of course, its a driver that’s not made by Sony and is designed to screw w/ your monitors resolution settings.
