4 Port HDMI 4K Quad View KVM Switch Pro A quad view 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 4K HDMI KVM Switch, with Quad View capabilities, allows users to simultaneously manage, operate and view 4 Full HD sources, such as PCs, servers or media players, on a single 4K display or projector and to control those sources with a standard USB keyboard and mouse. In Quad-View mode, the screen is split into four equal fields, each displaying the content of its related source. Sources can be switched using mouse selection or via keyboard control. A full screen mode for a single source is also accessible via the middle mouse button. Additional switches can be installed in a cascade configuration which increases the number of sources that are controlled and displayed. Seamless switching from one source to another removes the black-out normally caused by the source and display “handshake”, making this device perfect for use in mission critical applications such as control room scenarios.
