  • Dual-monitor capability expands workspace via DVI-I and DisplayPort outputs

  • Compact adapter adds screens without internal hardware changes

HP Dual Output USB Graphics Adapter

The HP C5U89AT adds two video outputs through one USB 3.0 Micro B port. It supplies a DVI-I connector and a DisplayPort connector for expanding desktop space on Windows or macOS systems. No internal hardware changes are required for installation.

Suitable for office workers

Buyers whose computers lack a free USB 3.0 Micro B socket cannot use this adapter. It is also not intended for high-frame-rate gaming or colour-critical professional graphics workloads.

Single USB 3.0 Micro B host connection

The entire dual-display link runs over one USB 3.0 Micro B cable, so the host port must support the necessary bandwidth and driver stack. Verify that the operating system and USB controller meet the adapter's requirements before purchase.

Questions about this item

How do I install the HP C5U89AT Dual Output USB Graphics Adapter, and which step is most often missed?

Connect the USB 3.0 Micro B cable to the host, attach monitors to the DVI-I and DisplayPort outputs, then install the DisplayLink driver before the OS detects the displays; skipping the driver install is the common mistake.

What maintenance or replacement will the HP C5U89AT adapter need over time?

The unit has no moving parts or user-serviceable components; keep the USB 3.0 Micro B port and video connectors free of dust, and replace the adapter only if the USB interface or video outputs fail.

What limit appears first when the HP C5U89AT runs sustained dual-monitor workloads?

The USB 3.0 bandwidth and host CPU overhead for DisplayLink compression become the bottleneck before the adapter’s own thermal limits are reached.
