This KVM switch from Delock is a practical solution to operate four computers with HDMI output on one HDMI monitor. Furthermore, mouse, keyboard, printer or USB drive can be connected via four USB 2.0 Type-A ports. 4 in 1 Multiview Mode In Multiview mode, all 4 PCs are displayed simultaneously on one screen. The operation with keyboard and mouse is also possible without switching. When the mouse is moved over one of the desktops, it is activated for input. Alternatively, the Sync mode can be switched on, in which all connected PCs receive the same signals from the input devices. Flexible control The active computer can be selected by mouse button, keyboard hotkey, button on the device or infrared remote control. Note KVMs emulate a standard 104-key wired keyboard and a generic 2- or 3-button wired scroll wheel mouse on the respective console ports. Whether a wireless or gaming mouse and keyboard will work with KVM switches depends on several factors; in general, most wireless mice and keyboards do not support working with KVM switches. We recommend using a standard wired mouse and keyboard with our KVM switches.
