Dual 4K 30 Hz displays from one USB 3.0 port

This StarTech USB32HD2 adapter adds two independent HDMI outputs through a single USB 3.0 connection. It targets laptop and desktop users who need extra screen space but lack native video ports. The device draws power directly from the USB bus, removing the need for an external supply. It suits office multitasking, trading desks and home working setups.

One port drives 4K the other stops at 1920 x 1200

The primary HDMI output supports 3840 x 2160 at 30 Hz while the secondary output is limited to 1920 x 1200. This asymmetric resolution ceiling is the single specification that decides whether the adapter fits a given monitor pair. Buyers planning two equal 4K panels should note the second port cannot match that resolution. The chipset provides 64 MB of DDRII SDRAM frame buffer.

Fanless silent operation with minimal USB power draw

No moving parts means completely silent running in normal office use. The aluminium enclosure dissipates heat passively so surface temperatures stay low during extended sessions. Power consumption stays within standard USB 3.0 limits, avoiding extra cables or adapters. The compact 0.60 x 2.60 x 12.40 inch form factor adds negligible bulk to a travel kit.

Questions about this item

Which USB standard does the adapter use and what bandwidth does that provide for video?

The adapter connects via USB 3.0, which supplies enough throughput for 4K 30 Hz on the primary output and 1920 x 1200 on the secondary output simultaneously.

How much space does the adapter need on my desk and what mounting options exist?

The unit measures .60 x 2.60 x 12.40 inches and weighs 2.00 oz; it has no mounting brackets and sits inline between the USB cable and two HDMI cables.
