Dual HDMI USB 3.0 Adapter

The Boxwave JUA365 adapter connects two external displays to a single USB-A 3.0 port on Windows or macOS systems. One HDMI output supports 3840 x 2160 resolution while the second handles up to 2048 x 1152. Driver installation is required before use.

Replaces internal graphics upgrades

This adapter adds multi-monitor capability without opening the computer case or installing a discrete graphics card. The jump is worthwhile when the host device lacks spare video outputs or when internal expansion slots are unavailable.

Suits users adding dual screens

Ideal for professionals who need extended desktop space for multitasking across two monitors. Not suited for buyers who require higher refresh rates at 4K, need more than two additional displays, or want a solution that works without driver installation.

Questions about this item

Does this adapter need a USB-A 3.0 port to run both HDMI outputs?

Yes, it connects through a USB-A 3.0 socket to drive the dual HDMI outputs.

Is a driver install required before the second monitor appears on Windows or macOS?

Driver installation is required on both Windows and macOS; the adapters will not activate the extra displays until the driver is installed.

If one HDMI port fails, can I replace just that port or must I replace the whole adapter?

The HDMI ports are fixed on the adapter body, so a port failure means replacing the complete unit.
