4. Troubleshooting
1. Fuzzy, blurry, or ghosting image
Make sure that you are using the power supply adapter that
came with the unit. 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 AC505A relies on the power adapter that it comes with.
Do not substitute any other power supply or DC power
source.
