What the switch does

The Corn Electronics HDMI Bi-Directional Switch routes signals in two ways: connect two source devices to one display, or send one source to either of two displays. A manual button selects the active path. It is aimed at home-theatre owners, gamers and office users who need to swap HDMI sources without unplugging cables.

Resolution and cable limits

The unit passes 3D, 1080p and 4k x 2k video at data rates up to 3.4Gbps. The supplier notes reliable operation with cables 16 feet or shorter built to 26AWG or better; longer or thinner cables may cause signal loss. Only one output is active at a time, so simultaneous display on two screens is not supported.

Installation notes

No drivers or external power are required; the switch draws 15ma from the HDMI line and lights two green LEDs to show the selected port. Plug sources and displays into the HDMI sockets, then press the button to change routing. The most common issue is using cables longer than the recommended length, which can prevent a stable 4k handshake.

Questions about this item

Should I pick the 2-in-1 or the 1-in-2 mode for my setup?

Choose 2-in-1 to connect two sources such as a PS4 and a Blu-ray player to one TV; choose 1-in-2 to send one source to either a monitor or a projector, one at a time.

What does the 3.4 Gbps rating mean when I plug it in?

It is the maximum data rate the switch can pass, enough for 4K 2K resolution, 1080p and 3D content without signal loss.

How does the HDMI interface limit cable length here?

The maker advises cables of 16 feet or less and 26 AWG or thicker; longer or thinner cables may cause dropouts.
