Optimizing Image Performance

Two controls in the on-screen display can be adjusted to improve image performance: Clock and Clock Phase.

NOTE: The Clock and Clock Phase controls are adjustable only when using an analog input. These controls are not adjustable for digital inputs.

The Clock must first be set correctly since the Clock Phase settings are dependent on the main Clock setting. Use these controls only when the auto-adjustment function does not provide a satisfactory image.

●Clock—Increases/decreases the value to minimize any vertical bars or stripes visible on the screen background.

●Clock Phase—Increases/decreases the value to minimize video flickering or blurring.

NOTE: When using the controls, you will obtain the best results by using the auto-adjustment pattern software utility provided on the CD.

When adjusting the Clock and Clock Phase values, if the monitor images become distorted, continue adjusting the values until the distortion disappears. To restore the factory settings, select Yes from the Factory Reset menu in the on-screen display.

To eliminate vertical bars (Clock):

1.Press the Menu button on the monitor's front panel to open the OSD Menu, and then select Image Control > Clock.

2.Press the + (Plus) or – (Minus) buttons on the monitor's front panel to eliminate vertical bars. Press the buttons slowly so that you do not miss the optimum adjustment point.

1.Press the Menu button on the monitor's front panel to open the OSD Menu, and then select Image Control > Clock Phase.

2.Press the + (Plus) or – (Minus) buttons on the monitor's front panel to eliminate flickering or blurring. Flicking or blurring may not be eliminated depending on your computer or graphics controller card installed.
