4-Port Dual DVI KVM Switch

The StarTech SV431DD2DUA lets one user control four multimedia computers from a single keyboard, mouse and dual DVI monitor setup. A built-in USB 2.0 hub and 3.5 mm audio ports keep peripherals and sound shared across all connected systems. It is aimed at office or home workstations that need quad-system access without duplicate hardware.

Check your console and cables

Your console must provide two DVI-I single-link inputs for video, four USB-A ports for keyboard, mouse and hub devices, plus 3.5 mm jacks for microphone and speakers. Each of the four target computers needs dual DVI outputs and USB ports to match the switch’s computer-side cables. Verify that your required resolutions fall within 2048x1536 at 85 Hz analog or 1920x1200 at 60 Hz digital. Hot-key switching requires a standard USB keyboard.

Metal chassis with front-panel controls

The 4.05 lb metal enclosure sits on a desk and uses push buttons for manual port selection alongside green and red LEDs that show power, host-online and host-selected status. Rear-mounted 24-pin DVI-I, USB-A and 3.5 mm connectors keep cable runs tidy and reduce daily plug wear. The fixed computer cables mean the unit stays anchored while you switch between systems.

Questions about this item

What cables come in the box and which ones do I need to buy for four dual-DVI computers?

The switch provides four dual DVI ports, four USB-A ports and 3.5 mm audio jacks for the console; you must supply four DVI cables, four USB cables and audio cables to connect each computer.

Should I choose the analog 2048x1536 @85Hz mode or the digital 1920x1200 @60Hz mode for my monitors?

Use the digital 1920x1200 @60Hz setting for DVI-D or DVI-I digital monitors; the analog 2048x1536 @85Hz figure applies only to VGA signals through a DVI-I adapter.

How does the 1920x1200 @60Hz digital resolution look when I switch between four computers on dual monitors?

Each computer can drive both monitors at 1920x1200 @60Hz over DVI, and the front push buttons or hot keys let you swap all four systems instantly without losing signal sync.
