ATEN CS1924M 4-Port USB 3.0 4K DisplayPort MST KVMP Switch
PRODUCT DESCRIPTION
ATEN CS1924M 4-Port USB 3.0 4K DisplayPort MST KVMP Switch - 2 Years Local Warranty
Two Displays from One DisplayPort Cable
The CS1924M has a built-in DisplayPort Multi-Stream Transport (MST) hub, so a single DisplayPort connection from each computer drives two monitors at the console, one on DisplayPort and one on HDMI. Four computers share one keyboard, mouse, dual-monitor setup, speakers and microphone.
Sharp 4K and High Refresh
Video reaches 4K UHD (3840 x 2160) and 4K DCI (4096 x 2160) at 60 Hz, or 2560 x 1440 at 144 Hz. DisplayPort Dual-Mode (DP++) also passes HDMI and DVI signals via adapter.
USB 3.1 Gen 1 Hub
A 2-port USB 3.1 Gen 1 hub shares drives, printers and other peripherals at up to 5 Gbps. KVM, USB hub and audio focus can be switched independently.
Four Ways to Switch, Cables Included
Change computers with front-panel pushbuttons, hotkeys, the USB mouse or RS-232 commands. Power On Detection automatically moves to the next powered computer, and all KVM cables are included.
