Black Box ServSwitch DT - KVM switch - 4 ports - TAA Compliant

Switch PCs with single-link DVI-D video and emulated USB keyboard/mouse. This USB KVM switch enables you to access up to four CPUs with high-resolution DVI video connectors from a single workstation. Set up desktop KVM switching with high-quality DVI-D video. The ServSwitch DT DVI with Emulated USB Keyboard/Mouse supports full DVI at resolutions up to 1920 x 1200 at 60 Hz. Plus you can fine-tune the signals depending on signal strength. For easy hotkey switching choose the ServSwitch DT DVI with Emulated USB Keyboard/Mouse. Emulation means unselected computers continue to see the identities of the keyboard and mouse which means no enumeration is necessary when their link becomes active once again. This not only helps to make reconnecting faster but it also increases switching reliability. This is important because USB links are at their most vulnerable during the switching process. What's more the switch supports stereo audio signal switching for speakers and microphones. Audio channels can be switched independently from USB and video.
