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.

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.
