Four-input two-output HDMI switch

The AUBEAMTO 4x2 HDMI 2.0 switch splitter connects four source devices to two displays simultaneously. It handles 720p, 1080p and 4K at 30 and 60 Hz for home-theatre and presentation setups. Both outputs carry an identical signal so the same image appears on each screen.

Passive cooling with external power

The unit runs from an included 100-240 V AC adapter delivering 5 V at 2 A and has no internal fan. Operation is therefore silent in typical living-room or meeting-room environments. Power draw remains low because the device only routes and extracts signals without transcoding.

ARC and multi-format audio extraction

HDMI ARC support lets the switch return TV audio to an amplifier through the dedicated ARC port. Extracted audio is available simultaneously on coaxial, optical SPDIF and 3.5 mm jacks in 2.0 and 5.1 channel formats. Buyers needing independent matrix switching per output should look elsewhere.

Questions about this item

How do I connect four sources and two displays to the 4x2 HDMI switch, and what is the step people often miss?

Connect each source to one of the four HDMI inputs and each display to one of the two HDMI outputs, then power the unit with the included 5 V 2 A adapter. The step often missed is that both outputs carry the same signal, so you cannot show different sources on each screen.

What maintenance or replacement will the switch need over time?

The switch has no user-serviceable parts or cooling fans. The only item that may need replacement is the external 5 V 2 A power adapter if it fails after extended use.

What resolution or refresh-rate limit appears first when running 4K content continuously?

The HDMI 2.0 interface caps 4K signals at 60 Hz, so sustained 4K 60 Hz is the highest supported mode; higher refresh rates are not available on this device.
