External video adapter for multi-monitor setups

The StarTech USB32DVIPRO adds a DVI-I display to any computer with a free USB 3.0 Type-A port. It is aimed at office workers and mobile professionals who need a second or third screen without opening the case or using a discrete graphics card. A DVI-to-VGA adapter is included for legacy monitors.

USB 3.0 bandwidth caps resolution at 2048x1152

The adapter runs over a 5 Gbps SuperSpeed link and falls back to USB 2.0 if necessary, though high-resolution performance drops on the older bus. Maximum digital and analog output is fixed at 2048x1152, so 1080p panels work at native resolution but 1440p or 4K displays cannot be driven at their best quality.

512 MB DDR2 frame buffer decides the ceiling

Onboard memory is 512 MB DDR2 SDRAM paired with a DisplayLink DL3100 chipset, and this buffer size sets the hard limit for resolution and colour depth. Systems that need higher pixel counts, deeper colour or GPU-accelerated 3D workloads will require a native video output instead.

Questions about this item

Which maximum resolution does the USB32DVIPRO support for both digital and analog DVI signals?

The adapter outputs up to 2048x1152 over its DVI-I port whether the connected monitor uses a digital or an analog signal.

What does the 2048x1152 headline resolution mean when the adapter is connected to a real PC?

It provides a usable desktop at that resolution over a single USB 3.0 link using the DisplayLink DL3100 chipset and 512 MB of DDR2 memory.

What interface does the USB32DVIPRO use and what bandwidth does it cap at in practice?

It uses a USB 3.0 Type-A connector running at 5 Gbps SuperSpeed, which is the practical throughput limit for the video data.
