This is a great little switch which works great when using only HDMI connections, but we had purchased it to use with a HDMI-to-miniDisplayPort cable which does not appear to work with it. I believe it's because power can be delivered over HDMI but not over mDP, and so we need a powered switch for our purposes. We tested this switch with 2 HDMI cables though and it worked fine – so no complaints about the switch itself, it just isn't suitable for our needs. If you plan to use this switch with any other type of connection via HDMI I would suggest purchasing a powered switch.
