Dual HDMI and DVI output

This adapter adds one HDMI port and one DVI port to any Windows or Mac system through a single USB 3.0 connection. It uses the DisplayLink DL-3900 chipset to drive two external monitors simultaneously without requiring an internal graphics upgrade. The device draws power directly from the USB port so no external power supply is needed.

Compact bus-powered enclosure

The white plastic housing measures 2.87" x 2.01" x 0.81" and weighs 0.10 lbs, making it easy to carry alongside a laptop. A captive USB 3.0 cable connects to the host while the HDMI and DVI-I sockets sit side by side for straightforward cable routing. The package includes a software CD and installation guide for driver setup.

Silent operation with 5.1 audio support

Because the adapter has no moving parts it runs completely silent during normal use. The USB 3.0 interface provides up to 5 Gbps bandwidth to sustain Full HD 1920x1080p and 2048x1152 resolutions across both screens. HDMI output also carries 5.1 channel surround sound for multimedia playback.
