Sony BRAVIA DMX-SW1

The Sony BRAVIA DMX-SW1 Input LInk Module is a device that connects to any compatible BRAVIA television, or any other television with an HDMI port, and adds four HDMI ports. If the DMX-SW1 is connected to a BRAVIA television, it can be mounted on the back of the TV and integrates with the BRAVIA's menu interface and remote.

  It can output up to 1080p. It does not automatically switch ports based on activity; the user much manually tell the device which port to output to. Essentially, it is a fancy BRAVIA-branded HDMI video switcher.
