sharing (via a USB hub attached to the USB mouse port), and a rich bass

functionality – simply double-click on a USB mouse’s scroll wheel to

video synchronization technology which eliminates boot-up display

problems and optimizes resolution when switching between ports.

feature means that if one of the computers is powered off, the KVM

switch will automatically change focus to the other powered computer.

Featuring an unbeatable combination of DVI, USB 2.0, audio and

enhanced user-friendly operations, the GammaView Aluminus 2555/4555

allow users to keep up with the latest innovations in desktop multimedia
