Brightness Control
Use the brightness control to adjust the overall intensity of the display.
After allowing the CRT to warm up for at least a minute, adjust for the
least amount of brightness needed to make the display clearly viewable.
Adjust the brightness to match the brightness level in the room so that
the level will be easy to see.
1. Display the OSD.
2. Use the arrow keys (
>
or
<
) to select the brightness adjustment box.
3. Adjust the brightness value to its lowest setting. (For example, black
background with no text).
4. Adjust the brightness until black changes to dark gray.
5. Adjust the brightness down until the bar changes back to black. This
is the optimal brightness setting given the current lighting
conditions.
Note: Pressing the arrow keys simultaneously while the
brightness adjustment box is displayed sets the standard
level.
6. Proceed to make other adjustments as necessary.
Note: If you wait ten seconds, the display will automatically close
the window, memorize the settings and complete the
adjustments.
