Chapter 3: Installation
3. Installation
• Before installation, power off all devices that will be connected to this system.
• Make sure that all devices you will connect are properly grounded.
• Place cables away from fluorescent lights, air conditioners, and machines that
are likely to generate electrical noise.
NOTE: If you encounter no screen display after connecting a device:
1. Make sure the device cables are correctly and firmly attached.
2. Set your display device’s input source as HDMI.
3. Check the PC BIOS configuration for the video output settings.
4. Connect your computer to the display DIRECTLY to check if the video signal can
get through.

Chapter 3: Installation
Figure 3-2. 4-Port Video Switch (AVSW-HDMI4X1).
3.2 Installation Steps
1. Use an HDMI cable to connect the display to the video output port on the
back of the switch. For models that support the standard audio feature
(AVSW-HDMI4X1A or AVSW-HDMI2X1A), plug a set of audio jacks from the
speaker to the switch’s speaker port.
2. Use an HDMI cable to connect the source device to the video input port on the
switch. For the models that support the audio feature (AVSW-HDMI4X1A or
AVSW-HDMI2X1A), use an audio cable to connect the speaker port between
the input side of the unit and the corresponding output port on the source
device.
3. Plug the power supply into the switch and power on the switch.
4. Turn on the display (monitor, projector, or TV) and then power on the source
device(s).
NOTE: When each video source is powered on, make sure it has a display pointing
to it for EDID communication. If a source does not have a display pointing
to it, a video image might not display.
