Power on the monitor and the computer.
To install the monitor driver, insert the Reference and Driver CD, click Install
driver, and follow the on-screen instructions.
To optimize your monitor image, press the Automatic Image Setup key. Automatic
image setup requires that the monitor is warmed up for at least 15 minutes. This is
not required for normal operation.
Note: If automatic image setup does not establish the image that you prefer, perform
manual image setup. See “Manual image setup” on page 3-4.
