Four-computer VGA KVM switch

The ATEN CS84U lets one VGA monitor, keyboard and mouse control four computers. It accepts both PS/2 and USB keyboard and mouse ports on each connected system. Front-panel push buttons and hot-key sequences switch the active computer. Auto-scan cycles through ports at 3, 5, 10 or 20 second intervals.

Mixed PS/2 and USB environments

Suits administrators who manage a rack of legacy and newer servers that still use VGA video. Not suited for setups that require digital video such as DVI, HDMI or DisplayPort. Buyers needing more than four computer ports should look at a larger switch.

2048 x 1536 maximum video resolution

The switch passes analog VGA signals up to 2048 x 1536. This resolution ceiling decides whether the unit matches the display and graphics hardware in use. Higher-resolution or digital-only monitors will not work at their native modes through this device.
