ATEN CS1844 4-Port USB 3.0 4K HDMI Dual Display KVMP Switch
PRODUCT DESCRIPTION
ATEN CS1844 4-Port USB 3.0 4K HDMI Dual Display KVMP Switch - 2 Years Local Warranty
Four Dual-Monitor PCs, One Desk
The CS1844 lets one keyboard, mouse and pair of HDMI monitors control four computers that each have two HDMI outputs. Speakers, microphone and two USB peripherals are shared too.
4K at 60 Hz or 144 Hz QHD
Each display runs at up to 4096 x 2160 or 3840 x 2160 at 60 Hz, or 2560 x 1440 at 144 Hz. The switch is HDMI 2.0 and HDCP compliant, and Video DynaSync keeps resolutions correct when switching.
USB 3.1 Gen 1 and Independent Switching
A 2-port USB 3.1 Gen 1 hub runs at 5 Gbps. KVM, USB peripherals and audio can be switched independently, so a print job or audio stream can stay on one computer while you work on another.
Five Ways to Switch, Quad-Display Ready
Use pushbuttons, hotkeys, the mouse, RS-232 commands or the supplied remote port selector. Two units can be daisy-chained for a quad-display setup.
