This KVM switch by Delock is a convenient solution for connecting four computers with DisplayPort output to one DisplayPort monitor. Additionally there is an HDMI output for connection of two monitors, of which only one can be active at a time. Peripheral devices Furthermore, two USB 2.0 ports for a mouse and keyboard, and two USB 3.0 ports for a hard drive or USB memory can be connected. Flexible Control The active computer can be selected by mouse gesture, keyboard hotkey, button on the device or infrared remote control. Multi-Stream Transport (MST) With the support of MST (Multi-Stream Transport), multiple monitors can be used at the DisplayPort output with an optional MST hub.   Note KVMs emulate a standard wired 104 key keyboard and wired generic 2 or 3 button scroll wheel mouse on their respective console ports. Whether or not a wireless or gaming mouse and keyboard work with KVM switches depends on several factors; in general, most wireless mice and keyboards do not support working with KVM switches. We recommend to use a standard wired mouse and keyboard with our KVM switches.   Specification • Connectors:   Input:   4 x DisplayPort female   4 x USB 3.0 Type-B female   8 x 3.5 mm 3 pin stereo jack female (audio)   1 x 3.5 mm 3 pin stereo jack female for optional IR-receiver   1 x DC 5 V power connector screwable   Output:   1 x DisplayPort female   1 x HDMI-A female   2 x USB 3.0 Type-A female (USB 3.0 Hub)   2 x USB 2.0 Type-A female (keyboard + mouse)   4 x 3.5 mm 3 pin stereo jack female (audio) • Switching via button, mouse button, hotkey or infrared remote control • Automatic switching when turning a PC on or off • Supports HDCP 1.4 and 2.2 • Supports HDR • Supports MST (Multi-Stream Transport) • DisplayPort output:   Resolution up to 7680 x 4320 @ 30 Hz (depending on the system and the connected   hardware) • HDMI output:   Resolution up to 3840 x 2160 @ 60 Hz (depending on the system and the connected   hardware) • Robust metal housing • Colour: black • Dimensions (LxWxH): ca. 243 x 75 x 26 mm   Power supply specification • Wall power supply • Input: AC 100 ~ 240 V / 50 ~ 60 Hz / 0.6 A • Output: 5 V / 3 A • Ground outside, plus inside • Dimensions:   inside: ø ca. 2.1 mm   outside: ø ca. 5.5 mm   System requirements • PC with DisplayPort female + USB Type-A female • Monitor or TV with DisplayPort or HDMI interface • Connection cables   Package content • KVM switch with USB and audio • Remote control • 4 x cable USB 3.0 A male to USB 3.0 B male, length ca. 1.0 m • External power supply • Mounting brackets and screws • User manual
