Chapter 2: Overview
2. Overview
2.1 Introduction
The 2 x 1 or 4 x 1 HDMI Switch 4K enables users to quickly and easily share display
devices (HDTV, Blu-ray player, HD-DVD, Xbox, Wii, PS3, satellite receiver, etc.) from
your device inputs to one output device (monitor, projector, or TV). You can select
the desired input source within the range of 16.4 feet (5 meters) via the remote
control or push button located on the switch. You don’t need to plug and unplug
video sources, so A/V equipment is more convenient, more affordable, and more
efficient.
The HDMI Switch with Advanced Auto-Sensing includes Auto mode and Priority
mode functions. The system can either automatically select the latest video source
for display in Auto mode, or automatically select a video source following priority
order in Priority mode. And it also offers EDID Copy function to ensure the optimal
resolution for your application.
The built-in serial interface allows users to control the HDMI Switch through a PC,
serial controller device, or home theater system, integrating the whole A/V
environment.
2.2 Features
• Select one output device from 2 or 4 different sources.
• Autosensing function automatically selects active input source or prioritized
source.
• Control the switch via the front-panel push button, IR remote controller, or, for the
4-port model, via the serial connection.
• Individually turn ON/OFF the output port.
• Locking HDMI cables keep your connections secure.
• 3D-video, HDCP compliant, and Blu-ray ready
• Non-volatile memory stores all settings in case of blackout.
• Innovative technology designed to avoid unnecessary flicker when adding system
instruments.
• Signal optimization chooses the best output setting from the available alternatives.
• HDTV, 3D HDTV compatible.
• Supports resolutions up to Full HD 1080p/4K (3840 x 2160).

Chapter 2: Overview
Advanced Autosensing
• Select ports in Priority, Auto-sensing, and Switch modes.
- In Priority mode, the system automatically selects highest priority source to display
(Priority order: Source-1 > Source-2 > ……).
- In Auto-sensing mode, the system automatically selects the latest video source to
display.
- In Switch mode, the system selects the outputs to switch.
• Switch outputs by pressing a button or setting priority.
EDID Function
• EDID Copy and EDID Pre-setting ensure accurate output display.
• Set to separately learn audio and video EDID for multimedia/home theater system
integration.
• Emulating EDID information ensures optimum video performance.
• Read and store the EDID from the connecting display to the video extension.
2.3 What’s Included
Both switches include:
• 2 x 1 HDMI Switch 4K (VSW-HDMI2X1-4K) or 4 x 1 HDMI Switch 4K
(VSW-HDMI4X1-4K)
• Power adapter
• IR remote controller
• Set of foot pads
• This user manual
4 x 1 HDMI Switch 4K (VSW-HDMI4X1-4K) also has:

Chapter 3: Installation
3. Installation
WARNING:
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.
3.1 Device Connection
1. Use a video cable (HDMI) to connect the display to the video output port on the
unit.
2. Use a video cable (HDMI) to connect the source device to the video input port on
the unit.
3. Apply power to the unit.
4. Turn on the display (monitor, projector, or TV) and then power on the source
device(s).
5. If necessary, apply the EDID Copy process (see Section 4.2.2, EDID Setting).
NOTES:
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.
If no screen displays, follow these steps:
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 video source to the display DIRECTLY to check if the video signal
gets through.
5. Apply EDID Copy to your display (see Section 4.2.2, EDID Setting).
