Where most KVMs allow you to only switch connected peripherals between two computers, the IOGEAR GCMS1922 allows you to work on two connected computers simultaneously and has two modes that allow flexibility in your workflow. In Extension Mode, like traditional KVMs, you can switch the focus of the KVM from one computer to the other. In Matrix Mode, you can view both computers at the same time by having each of your two connected displays show one computer each. Toggling between modes is easy. You can use the mode button on the front panel of the GCMS1922, the included wired remote, mouse wheel button, or hotkeys. The GCMS1922 is the ideal tool for multi-tasking users who need to work on projects and applications across two machines without missing a beat.
