How to Force a Resolution in Windows Using the Registry

Although Microsoft Windows operating systems come with specific resolution settings already installed, you don't have to stick with them.

To change registry resolution settings, use the Windows registry editor utility that comes as a standard feature with all versions of the Windows operating system.
