Connects Four Computers to Two 4K Monitors and a Single Keyboard/Mouse
This dual-monitor KVM switch lets you access, control, boot and reboot four computers or other devices with HDMI ports and switch back and forth among them. It’s ideal for work-from-home applications in which you’d like to share two monitors between your home and work computers. All connected computers share two HDMI 4K monitors and one USB keyboard/mouse, which saves space on your desk or workspace. 

Switching Between Computers Is Fast and Easy
Use the front-panel push buttons, hotkey commands, mouse movement, RS-232 commands or the included remote port selector for quick and easy toggling among computers. You can also use the Auto Scan feature to scan all connected computers in five-second intervals automatically. LEDs indicate which computer is currently selected.

Transmits Crystal-Clear 4K Video with Digital Audio
The B006-HD2UA4 supports video resolutions up to 4K UHD (3840 x 2160 @ 60 Hz) and 4K DCI (4096 x 2160 @ 60 Hz) on two HDMI monitors, as well as 2.1-channel surround sound for music, movies and games. Independent audio switching lets you listen to music or a podcast on one computer, while simultaneously working on a different computer. Front-panel audio jacks have priority over the rear-panel jacks. A DCC (Daisy Chain Control) port lets you connect two B006-HD2UA4 KVM switches for a quad-display installation.
