USB 3.0 Dual HDMI Adapter

The LORDWORLD JUA365 connects two external monitors to a single USB-A 3.0 port. One HDMI output reaches 3840 x 2160 resolution while the second delivers up to 2048 x 1152. Driver installation is required on both Windows and macOS before use.

Office multitaskers and laptop users

Suits people who need extra screen space for documents, code or web pages without opening their computer. Not for gamers or video editors who rely on GPU-accelerated 3D performance, high refresh rates or HDR colour pipelines.

Asymmetric 4K plus 2K output

The deciding specification is the split resolution ceiling: one port at 4K UHD and the other capped at 2048 x 1152. If your workflow demands matching 4K signals on both screens, this adapter will not meet that need.

Questions about this item

Should I use the 4K HDMI port or the 2048 x 1152 port for my main monitor?

What resolution will I actually see on each screen when I plug this JUA365 into a USB-A 3.0 port?

One HDMI output can drive a panel at 3840 x 2160, the other at 2048 x 1152, giving two independent desktops from a single USB-A connection.

Does the USB 3.0 link limit the resolution or refresh rate on the 4K output?

The adapter negotiates the highest timings the host allows; the USB 3.0 bandwidth supports the stated 3840 x 2160 and 2048 x 1152 modes.
