I can't get the key combination to work, but it's not that hard to just press a button on the front panel. horrible flickering because I'm actually using UHD/4K resolution and the cables shipped are too cheap to reliably transmit the signal. After throwing the included HDMI cables in the trash and plugging in a few good ones, everything seems fine. I was actually surprised that they included wires, and I think they should stop before someone inevitably blames the switch itself for the flickering.
