Blackbird 4K 3x1 HDMI Switch In a technology driven world high definition content has become the standard. If you love watching movies and playing the latest and greatest games in HD, you need to be able to connect your HD devices to your display. Normally you would connect each device to an HDMI® input on your display, but what if you only have one input? With these switches, you can easily change between multiple sources using the included remote or directly on the switch itself, instead of constantly swapping out cables. These switches not only push up to 4K HDCP protected video content to your display or TV, they also push compressed audio content, such as Dolby TrueHD™ or DTS-HD Master Audio™, and uncompressed audio content, such as LPCM. Whether your need is at home, at school, or at work, these switches are the perfect portable solution to view HD content from multiple sources on one display without complicated configurations or swapping cables.
