Use the UP and DOWN buttons to move to the relevant setting. Press
the SELECT button, and use the UP and DOWN buttons to alter the
setting. Press SELECT to confirm the change. Once you are satisfied
with the contrast settings, press MENU to return to the main menu.
Geometry/Positioning
To alter the position and horizontal size of the displayed image, select
the geometry option from the menu. This will bring up a sub-menu
allowing you to alter the horizontal size, and the horizontal and vertical
position of the image.
Horizontal Size Adjustment
If the Horizontal Size setting of your image is not fine-tuned, you may
observe periodic vertical bars of video noise. These bars of noise are
usually adjusted out when an Auto Adjust is performed. If the bars of
noise are still present, this setting can be adjusted manually.
Adjust this setting so that the vertical bars of noise are replaced by
either an even amount of noise across the whole screen, or the noise
disappears completely. Any remaining noise can be eliminated by
adjusting the Fine Phase Setting.
Fine Phase Setting
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. This noise can be eliminated by
adjusting the Fine Phase setting.
If you change your display to Windows shut down mode, this noise will
be more visible, and easier to eliminate. Click on the "Start" button at
the bottom right side, then click Shutdown. This will bring you to the
Windows shutdown mode. After finishing phase adjustment, click on
"Cancel” to return to your original Windows display.
If you do an Auto Adjust, the monitor will try to find the best Clock
Phase setting. If you are not satisfied with the auto adjust, please fine-
tune the phase manually as described above.
Sharpness
The Sharpness option can be used to adjust the sharpness of the picture
when lower resolutions are being displayed.
