Problem: After the startup screen, or after display settings are changed,

the screen image is garbled or unusable

Cause

The MGA display driver may be trying to use settings your monitor doesn’t support. This

can happen if a monitor was never selected in the software and the display resolution was changed to

one your monitor doesn’t support, or if the monitor connected to your computer was changed without

it being changed in the software.
