Mode and Image Adjustment
Not all video controllers produce exactly the same video output levels or the same timing.
The VT1040 uses onscreen programming to make setup and adjustment easy. The menus
are selected and the menu items are adjusted using the buttons located on the monitor
front panel. These buttons are enabled or disabled by a rocker switch labeled SET UP
located on the side of the monitor. This feature is provided to inhibit tampering once the
monitor is in actual use. Turn the SET UP switch to the On position to enable set up and
adjustment. Prior to adjusting your monitor you should initialize the display settings in
the Windows control panel to the following choices:
Note: The monitor type option is not available in Windows NT.
Once the monitor is powered up, you can access the onscreen display (OSD) functions by
pressing the menu button. After the menu appears, select the Auto Setup function
following the directions given below. The monitor will automatically adjust to the
incoming video signal. Then select the Image | Auto phase function or manually fine-tune
the image. Finally, set the brightness and contrast settings to your individual preference.
