I have a Gateway GT5692 Vista
It gives a selection to make screen fonts larger. I chose the largest, 120 dpi I think or maybe larger than that. Anyway, screen suddenly went so large it overextended the computer monitor, that is, the button to change it back to normal went BELOW the screen so I am unable to get screen back to a size that is readable, in other words, I can do NOTHING with it because there is no way to make a CHANGE, all I see is a giant red screen. Surely there must be a way to get it back to a normal size. Any help? Thanks.
Surely there must be some method to

Right click on the title bar of the window and select Move, then use your cursor keys to move it up until you can see the button.

Also should be able to right click anywhere on the screen and change the resolution size. Display / settings.
