4. Troubleshooting

1.Fuzzy, blurry, or ghosting image

The VGA cables must be of high quality multi-coaxial construction. If you are using long video cables in excess of 100 feet, the losses in the cable could be a contributing factor, in which case, first reduce the refresh rate to 60 HZ and if that is not enough, you may have to reduce the resolution of the incoming video signal.

2.The PC does not recognize a Plug-and-Play monitor

If the PC’s Operating System is setup to detect a plug-and-play monitor (usually in Display Properties Advanced Settings), it may have trouble finding a monitor. If the PC does not produce an image due to this, disable the plug-and-play monitor detection in the PC’s operating system Display Properties.

3.Substituting power supplies

The AC506A relies on the power adapter that it comes with. Do not substitute any other power supply or DC power source.
