Selecting the Brightness option (as in Figure 3) allows you to adjust the brightness
of the display. Adjust the brightness using the
UP
and

Phase
If the phase of your monitor is not fine-tuned, you may observe unstable
horizontal noise lines and cross-talking, stretching from the edge of small
windows on your display.
To reduce this horizontal noise, follow these steps:
1. From the Windows desktop of the host computer, select
Start
and then select
Shut Down
. The Windows Shut Down dialog box appears on the monitor’s
display. (Visual noise is more visible and easier to eliminate if the display is
in Windows Shut Down mode.)
2.
Press the Menu control button to call up the OSD main menu, select the PC
icon, and then select the Phase sub-menu.
3. Press the
UP
or
DOWN
control buttons to reduce the noise. To confirm a new
phase setting, press the
EXIT
control button.
4.
After adjusting the phase setting, select Cancel in the Windows Shut Down
dialog box to return to your original Windows display.
Frequency
If the Frequency setting is not fine-tuned, you may observe periodic vertical bars
of video noise.
To reduce this vertical noise, follow these steps:
1. Select AUTO in the OSD menu to auto adjust the monitor’s display (see
“Auto adjustment” on page 16).Vertical noise is usually adjusted out
when the display is auto adjusted.
If there is still noise after auto adjusting the display, adjust the OSD
Frequency setting.
2. Press the Menu control button to call up the OSD main menu, select the
PC icon, and then select the Frequency sub-menu.
3.
Press the
UP
or
DOWN
control buttons so that the vertical bars of noise
disappear completely or so that an even amount of noise is distributed
across the entire screen. To confirm a new frequency setting, press the
EXIT
control button.
4. If there is any remaining noise on the screen, adjust the Phase setting (see
“
Phase
” on page 17).
H-Position, V-Position
Selecting the H-Position or V-Position sub-menu allows you to adjust the
horizontal/vertical position of the displayed image. Press the
UP or DOWN control
buttons to adjust the position of the video image. To confirm a new position
setting, press the
