To change the size of a screen on a PC, If you are using a Desktop then configure the settings with the buttons on the screen... if there are any...



If you mean Screen resolution, right click the desktop and select properties. Then go to the last Tab (Settings) and you should be able to change the resolution there....





On a Mac: Hold down control and scroll inwards to zoom and vice versa for going out....



Or go to System Preferences (to change resolution) and click on Displays.



Hope this helps
