If the display image is not aligned with the screen, use the display's
controls to center the image (refer to the display manual for
instructions). If the screens generated by the applications do not appear
to be correct, check the application's manual to find out which video
standard is required. Also check your display manual to find out which
refresh rate is required. Use your operating system's procedures, to
select the correct refresh rate.

If Your Keyboard Does Not Work

Ensure that the keyboard is correctly connected (a keyboard icon

will be displayed on your screen if the keyboard is not connected).
If you turn on your PC Workstation, the operating system boots, and

the keyboard is correctly connected but still not available, the
power-on password may be set to "keyboard locked". You will need
to enter a password to unlock the keyboard and mouse. You can
change this setting in the Setup program. Refer to the Power Menu
in the HP Setup program.
