address as the integrated video interface (03B0h to 03DFh).

use the display's controls to center the image.
Refer to the monitor manual for information about the controls.
3. If the screens generated by the NOS do not look right, check the operating system manual to
find out which video standard is required.
Also check your monitor manual to find out which refresh rate is required.
4. If the screen goes blank after the NOS has booted, contact your HP support organization.
