If you’ve ever set up your TV to use with more devices than your TV has, you’re probably familiar with the HDMI switch. It’s a small box that accepts multiple HDMI inputs and directs them through a single output. With one, you can connect multiple devices to a single input on your television or monitor. Similarly, an HDMI splitter can take one input and output that video to two displays at the same time. Monoprice’s Blackbird 8K HDMI splitter/converter, as the name suggests, does both of these things.
