Connect extra monitors via USB 3.0

This USB 3.0 to DVI/VGA Pro adapter adds external displays to laptops or desktops without opening the case. It supports DVI and VGA monitors at up to 1080p or 2048x1152 resolution. DisplayLink Manager provides audio, video and rotation controls on Windows 10, Windows 11 and Mac M1 or M2 systems. Up to six adapters can run on one computer.

Check USB port and monitor inputs

Verify the host has a free USB 3.0 port for full bandwidth; USB 2.0 will limit performance. Confirm the target monitor accepts DVI or VGA input and matches the 16:9 aspect ratio at 2048x1152 maximum. Ensure the operating system is Windows 10, Windows 11 or a supported macOS release for DisplayLink Manager compatibility.

Replaces internal GPU upgrades or docks

This adapter suits users who cannot install a discrete graphics card or lack dock connectivity. It revives older DVI or VGA monitors instead of replacing them. The jump is worth it when you need multi-screen productivity on a portable or compact system and the built-in video outputs are already used.

Questions about this item

Does the SIIG JU-DV0112-S3 include the DVI-to-VGA converter or must I buy it separately?

The adapter ships with a DVI-to-VGA converter included, so no separate purchase is required.

Should I pick the 1080p or the 2048x1152 setting for my monitor?

Choose 2048x1152 if your display supports that native resolution; otherwise 1080p will scale correctly.

What does the 2048x1152 figure mean when the adapter is driven by a USB 3.0 port?

It is the maximum pixel grid the DisplayLink engine can push over USB 3.0, delivering a 16:9 image at that resolution.
