Manual image setup

If automatic image setup does not establish the image that you prefer, perform manual image

setup.

Note: Have your monitor powered on for about 15 minutes, until the monitor warms up.

1. Press at the bottom of the monitor to open the OSD menu.

2. Use or to select and press to access.

3. Use or to select Clock and Phase adjustment.

Clock (pixel frequency) adjusts the number of pixels scanned by one horizontal

sweep. If the frequency is not correct, the screen shows vertical stripes and the picture

does not have the correct width.

Phase adjusts the phase of the pixel clock signal. With a wrong phase adjustment, the

picture has horizontal disturbances in light picture.

4. When the image no longer looks distorted, save the Clock and Phase adjustments.

5. Press to leave the OSD menu.
