'Positioning' moves the viewing area around on the monitor screen.
When making changes to either the 'Horizontal' or 'Vertical' settings, no changes
will occur to the size of the viewing area; the image will simply be shifted in
response to your selection/change.
Minimum is '0' (-). Maximum is '100' (+).

Image settings:

Auto Adjust Even though your computer system can recognize your new flat pa nel monito r on

startup, the 'Auto Adjustment' function will optimize the display settings for use
with your particular setup.

Pixel Clock The 'Phase' and 'Pixel Clock' adjustments allow you to more closely adjust your

monitor to your preference. These settings are accessed through the main OSD
menu, by selecting 'Image Settings'.
Use the - and + buttons to adjust away interference. Minimum: 0 ~ Maximum: 100

9

Phase If satisfactory results are not obtained using the 'Phase' adjustment, use the 'Pixel

Clock' adjustment and then use 'Phase' again.

Color Settings:

'Color Settings' adjusts the color temperature and saturation.

Normal Preset 'Normal Preset' is selected to obtain the default (factory) color settings.

Blue Preset 'Blue Preset' is selected to obtain a bluish tint. This color setting is typically used

for text based applications (Spreadsheets, Programming, Text Editors etc.).

Red Preset 'Red Preset' is selected to obtain a redder tint. This color setting is typically used

for color intensive applications (Photograph Image Editing, Multimedia, Movies
etc.).
