as contrast, brightness, clock phase, and image position. To access the menu,
press and hold the minus (−) and plus (+) buttons at the same time. The OSD
menu is displayed (see Figure 51).

the display and at any time the video mode is changed, or the 4820 is
moved to another host system.
Manual Adjust
Allows you to modify the clock, phase, and image position.
Brightness
Allows you to modify the display’s brightness setting.
Contrast

frequencies.
Reset Presents Yes or No dialog box that allows you to reset the menu settings to
the default values.
To exit the OSD menu, press the minus (−) and plus (+) buttons at the same time.
The system saves your values.
The OSD menu times out after approximately 20 seconds of inaction. The system
does not save any of your values.
Using Manual Adjust: Normally, you do not need to use Manual Adjust because
Auto Adjust sets the parameters at the optimum value. However, Manual Adjust
allows you to fine-tune the display timings.
