An integrated USB 2.0 hub allows you to share USB devices such as pen drives, hard drives and printers, between the connected computers. The KVM Switch Pro use a robust metal housing which helps it remain securely seated on a desktop but also helps to avoid external interference when used in more demanding environments.

True Transparent USB Function True Transparent USB switching is an advanced USB emulation technology. It allows the KVM to recognise specific Keyboard and Mouse models and emulate any of their associated special key and function information. Unique Switching Options A unique switching arrangement allows the built-in USB hub to be switched independently of the computers allowing you to print from one PC whilst playing games on another.  Similarly, independent audio switching means you can listen to music from one computer while browsing the internet on the other DisplayPort 1.2 Support  Supports DisplayPort monitors and computers with video resolutions of up to Ultra HD 4K 60Hz, making it perfect for MRI, CAD, desktop publishing and digital video applications.
