Extending the VGA connection using a VGA amplifier/repeater
If you need to connect the display to a computer or other VGA source devices over a long
distance (over 3 meters), a VGA signal amplifier must be used to boost the signal and prevent
potential display quality problems like interference and ghosting.
1. Connect the VGA input jack on the display to the VGA output jack on the VGA signal
amplifier/repeater using a D-Sub (15-pin) cable.
2. Connect the VGA output jack on the computer to the VGA input jack on the VGA signal
amplifier/repeater using a D-Sub (15-pin) cable.
3. Connect the computer's audio output jack to the audio input jack on the display using a
suitable audio cable.
