Black Box KV9634A ServSwitch DT 4-Port DVI-D KVM Switch with Bidirectional Audio

Four multimedia computers, one console. Digital video runs to 1920 x 1200, the switch handles DDC2B emulation, and it is genuinely plug-and-play - nothing to configure before it works. Switch from the front-panel buttons or by hotkey, or hand it over to auto-scan at 3, 8, 15 or 30-second intervals.

Four USB ports and a device hub port support USB 1.1 or 2.0 high-speed peripheral sharing across the connected machines. Audio and microphone switching runs independently of the KVM channel, so the speaker feed does not have to follow the machine you are typing on.
