An enhanced KVM switcher from Gefen gives access to four computers using a single high resolution display with single or dual link DVI connectivity. The 4x1 KVM DVI DL switcher supports resolutions up to 3840 x 2400.
Internal EDID management eliminates the need to reboot when switching between computers, and restores the original resolution settings and desktop icons for each computer.
Two USB 2.0 ports support any keyboard or mouse combination, and stereo audio connections are also switched for each computer.
