A KVM switch allows an operator to conveniently control and manage multiple devices, such as PCs and servers, from a single keyboard, mouse and display console.

The Lindy 4 Port HDMI 4K60, USB 2.0 & Audio KVM Switch is a compact solution for providing access and control over four HDMI equipped PCs from a single keyboard, mouse and monitor setup.

Support for resolutions up to 4K Ultra HD 60Hz ensures the highest image quality, perfect for demanding graphical content in gaming setups, video editing or quad system control workstations. The additional support for High-Dynamic Range ensures video content can be seen with enhanced brightness, greater contrasts and a much wider colour gamut. The audio output ports on the main unit also allow users to connect headphones or speakers to add immersive 2CH audio and a microphone, pressing the Audio On/Off button on the front panel mutes these devices. These ports are not connected to the HDMI signal but to a built-in USB converter while an additional USB device  such as a printer, scanner or hard drive can be connected to the additional USB port on the front panel.

The KVM switch features two switching options including push buttons on the unit and keyboard hotkeys provide simple, reliable control for the user, great for both professional and first time users.
