The projected image may not fill your screen if the resolution is set incorrectly. To correct this:
Right-click on the desktop and find “Screen resolution”.
Select the projector from the options offered and change the resolution. NOTE: Make sure that the new resolution setting is within the recommended resolutions for the projector or monitor being used.
If the projector is still not filling out the screen as desired, confirm that your projector is mounted the correct distance from the screen. DO NOT CHANGE IN-GAME RESOLUTION settings without first changing resolution settings on your computer to insure compatibility with the projector.
