Abstract
A method of resetting the screen display mode in a computer system having a display monitor is disclosed. The method is arranged to reset the display mode while a designated operating system such as a windowing environment based operating system is running, without requiring the operating system or any currently running application(s) to be exited and reloaded. The method includes the step of receiving a user initiated input requesting a change in the display mode. After a display mode request is received, the operating system display characteristic variables are reset to values that are appropriate for the requested display mode. Additionally, the display driver display characteristic variables are reset to values that are appropriate for the requested display mode. Moreover, the hardware mode is set to a mode that is appropriate for the requested display mode. After all of these resetting steps have been completed, the display screen is repainted to display the images dictated by any program(s) that is/are currently running in the requested display mode.
