Pick a resolution, and then a refresh rate.
An incorrect Monitor Type setting may damage your monitor. Review
your monitor specifications before making a selection from the Monitor
Selection Menu.
A scrambled screen indicates your monitor is not capable of the selected
display mode. Immediately press ESC to exit.
If the monitor produces a scrambled display, try a lower refresh rate. If
it is already at the lowest refresh rate, set that resolution to Not
Supported.
