Mini DisplayPort MST Adapter

The LORDWORLD JDA156 adapter extends a single Mini DisplayPort 1.2 output to two independent HDMI displays. It supports extended, expansion or mirror modes for multitasking across two screens. The device is designed for Windows systems such as Microsoft Surface Pro 2, Pro 3, Pro 4 and Surface Book. Mac computers are not compatible with this adapter.

Sustained Multi-Display Operation

Dual 4K output runs at up to 30 Hz on each monitor when the host provides DisplayPort 1.2 with MST support. The adapter draws operating power from an external USB source and includes the required cable. Plug-and-play operation means no driver installation is needed for continuous daily use. Stable video output is maintained across both screens during extended sessions.

Thermals, Noise and Power Draw

The compact adapter has no moving parts and operates silently. Power is supplied entirely through the included USB cable, keeping system power impact minimal. No active cooling is required, so the unit remains cool during normal desktop workloads. The pass-through design adds negligible heat to the host device.

Questions about this item

Does the adapter draw enough power from the USB cable to run two 4K monitors at 30 Hz all day without overheating?

Yes, the included USB cable supplies the required external power so the JDA156 can drive both displays continuously at 4K 30 Hz without thermal issues.

What host port and standard does my laptop need so the JDA156 can output two independent 4K 30 Hz streams?

Your device must provide a Mini DisplayPort 1.2 connection with Multi-Stream Transport support; without MST the adapter cannot show separate images on each screen.

Will this adapter work alongside the Mini DisplayPort on my Surface Pro 2 or Pro 3 for a three-screen setup?

The JDA156 is designed for Surface Pro 2, 3 and 4, letting you add two external monitors while the built-in display stays active for a total of three screens.
