PRODUCT DESCRIPTION
ATEN CS1794 4-Port USB HDMI/Audio KVMP Switch - 2 Years Local Warranty
One Desk, Four HDMI Computers
The CS1794 lets a single USB keyboard, mouse and HDMI monitor control four HDMI computers, and share speakers, a microphone and two USB devices through its built-in 2-port USB 2.0 hub.
Full HD Video with HD Audio
HDTV resolutions from 480i to 1080p and PC resolutions up to 1920 x 1200 are supported, with Dolby TrueHD and DTS-HD Master Audio. Video DynaSync stores the monitor's EDID for clean boot-up and switching.

Four 1.8 m KVM cable sets (HDMI, USB and audio) are included, so the switch is ready to install out of the box.
