Product Review

Ran out of HDMI ports on your HDTV/monitor/projector? Want to reduce the mess of cables connected to it? Fosmon's 3x1 HDMI Intelligent Switch with Pigtail Support will take care of these problems. It has 3 HDMI input sources to provide plug-and-forget auto sensing capabilities that automatically switch inputs when a signal is detected. A button to manually switch between the 3 sources is also built-in.

Powered from Connected Devices
No power adapter is necessary to make this switch work, as long as the connected devices supply sufficient power. HDMI cables have the capability to deliver power from connected sources.

4K Support and HDMI Features
Up to 4K resolutions at 30fps, 36-bit Deep Color, 3D, and uncompressed/compressed audio formats are some of the newer HDMI features supported on this switch.

Features and Specifications
3 HDMI inputs / 1 HDMI output
Supports 12-bit Deep color per channel; maximum of 36-bits across all channels
Supports 3D devices
Supports up to 4K resolutions
Supports HDCP pass-through
Supports a total TMDS throughput of 8.91Gbps max
Supports uncompressed audio such as LPCM
Supports compressed audio such as DTS Digital, Dolby Digital, DTS-HS and Dolby TrueHD

NOTE
Plug-and-forget auto sensing only works correctly for devices that do not output continuous voltage over the HDMI port when turned off. Powering on a device gives it output priority over the other two devices. Output priority is given to the next device on the switch if the current output device is turned off. Make sure the connected devices supply enough power to the switch.
May NOT be compatible with devices requiring HDCP 2.2 (such as the Amazon Fire Box).
