External 4K display adapter

The FLEANE JUA354 adds a second screen to a laptop or desktop through a single USB 3.0 Type-A port. It carries an HDMI female connector so any standard HDMI cable reaches the monitor or projector. Driver installation is required on both Windows and macOS before the first use.

3840 x 2160 at 30 Hz headroom

The adapter drives one external display at up to 3840 x 2160 resolution with a 30 Hz refresh rate, suitable for office applications, web browsing and video playback. Higher refresh rates or multiple external displays exceed the available bandwidth and are not supported.

USB-A host with HDMI display

The host must provide a USB 3.0 Type-A port; the adapter falls back to USB 2.0 with reduced performance. An HDMI cable and a compatible display complete the link, freeing the computer's native video outputs for other tasks.

Questions about this item

Will this USB 3.0 to HDMI adapter work with my older USB 2.0 ports?

Yes, the adapter is backwards compatible with USB 2.0 ports, though the 4K 3840 x 2160 resolution at 30 Hz requires a USB 3.0 connection for full performance.

How can I confirm the adapter is delivering 4K at 30 Hz after I install the driver?

After installing the required driver on Windows or Mac, open your display settings and verify the external monitor shows 3840 x 2160 resolution at 30 Hz refresh rate.

Does the JUA354 package include an HDMI cable or do I need to buy one separately?

The adapter provides a female HDMI port, so you must supply your own HDMI cable to connect the adapter to your monitor or projector.
