4 Port 4K@60Hz Dual Monitor HDMI & DisplayPort USB KVM Switch Features & Specifications: 1. 4 computers/laptops share one set of keyboard, mouse and dual monitors, and more USB 2.0 peripherals; 2. This dual monitor HDMI & DisplayPort KVM switch supports up to 4Kx2K (3840*2160) @60Hz (HDMI 2.0, DP 1.2) for extended or mirrored display; 3. Support wired or wireless keyboard and mouse; 4. Compatibility with all computers and other devices with HDMI & DisplayPort ports; 5. Adaptive EDID can adapt to a variety of complex application environments; 6. Compatible with Windows 10/7/2000/XP/Vista, Linux, UNIX, Ubuntu, Fedora, and other systems; 7. Advanced switching modes: push button and wired remote. This 4 ports HDMI & DisplayPort dual monitor KVM Switch Supports Mirror Mode & Extended Mode: 1). Extended Mode can output two different screens and Mirror Mode can output two identical screens. 2). The requirement for this KVM to achieve a dual-screen display is that each PC you connect to has the capability to support a dual or multi-screen display. This has nothing to do with KVM. Detection method: You can connect the computer to 2 monitors directly (not via KVM). If both monitors have an on-screen display, the computer supports a multi-monitor display. Adapters Might Be Needed: This Dual Monitor KVM Switch requires HDMI & DisplayPort input for each computer and HDMI & DisplayPort output for monitors. However, most computers especially laptops do not have HDMI & DisplayPort output, thus reliable adapters will be needed for non-HDMI & DisplayPort outputs like VGA, DVI, and USB C. Two Switching Methods Button Switch: Quickly switch between the 4 computers with just one click of the switch button and no extra operations. Wired Remote Switch: A button-controlled switch extension cord is presented, so you don’t have to get up and switch easily when you use it. NOTE: Do not support keyboard switches, avoid hotkey conflicts.
