Troubleshooting
If there is no picture after a restart:

2- Recycle the power on the VGA to ADC Conversion Box.
3- Restart the computer and allow 5-10 minutes to reboot.
4- Make sure your computer is set to the native resolution of your ADC
monitor.
If the picture is blurry or jittery, you can turn the rotary switch next to the DVI connector
with a small flat head screwdriver until the picture is focused and the jitter is gone.
If there is a picture, but at the wrong resolution:
1- Open the monitor control panel and set for the native resolution
of the monitor.
