Right click the Desktop and choose Properties then Settings and set the Screen Resolution.

If by "few" you mean "view" than you have to reset the computer press F8 before windows starts and choose "start windows in safe mode". After windows starts up you can revert to the original display setting by using what rokytnji adviced you.
