Screen Resolution Changer

This project demonstrates how to change screen resolution (i.e. screen area in display settings) to any supported value on your machine.

Original Author: Vince Soto

Inputs

User sets screen resolution.

Assumptions

There are some extra API calls which are not used in this project because it is going into something bigger which uses several other graphics capabilities, such as recreating TransparentBlt from msimg32.dll because of the memory leak in the function in win9x.

Returns

Sets screen resolution based on default refresh rate values for resolutions.

Side Effects

Note: This is a basic sample, and does not prompt the user to insure the resolution chosen is compatible with the monitor (or monitor driver) installed on the computer. If you are unsure about your display capabilities, do not set the resolution higher than what you are currently using!
