TROUBLESHOOTING
No Picture appears on bootup:
If no picture appears on bootup, fi rst reset the VGA to DVI Scaler Plus to the native
mode of the display it is connected to.
Monitors without an internal scaler (Any Apple Display as well as the Dell 30"
monitor) require the VGA to DVI Scaler Plus to output the monitor's exact native
resolution to display a picture. To set the Scaler to the correct resolution, do the
following:
1. Reset the scaler to the native resolution of the display by fi rst holding down the
MENU button.
2. While holding the MENU button down remove the power supply from the scaler.
Note: The MENU button does not work without a source plugged in.
3. Wait 3 seconds and re-plug the power supply to the unit.
4. After you have inserted the power supply, let go of the MENU button.
5. Wait 3 seconds and the scaler will then reset to the displays native resolution.
6. If you need to start over for any reason, unplug and re-plug the power on the
VGA to DVI Scaler Plus and then repeat steps 1-5.
How to use the Auto-Adjust:
1. If for any reason you need to Auto-Adjust the display, you can do so by pressing
the "-" button once. Give the scaler 3 seconds to Auto-Adjust itself.
2. While the unit is powered on, press the - button with both source and display
connected and powered on as well.
3. Wait three seconds for the unit to adjust itself to the displays optimum settings.
4. After you have pressed the - button, a small dialog box will appear to show that
you are auto-adjusting the picture. It will disappear when the scaler is done.
