Image Controls - IBM Aptiva Hardware Handbook

To adjust the contrast and brightness controls:
1.
Be sure the monitor and system unit are turned on.
(The power indicator lights on the monitor and
system unit are lit when they are on.)
2.
Adjust the monitor controls until you get the effect
you want.
Adjustment tips:
•
Set the brightness level so that the background (the
black visible area just outside the data/text area) just
disappears.
•
Set the contrast level so that text does not appear
fuzzy. The edges of the characters should remain
sharp.

shape and position of the images you see on the screen.
These image controls are located on the front of the
monitor underneath the screen, typically behind a door.
The following are symbols for common image controls.
The symbols are located next to the controls. Your
monitor may have some or all of these controls.

image.
