Overview

The JDA146 mini DisplayPort(TM) to Dual DisplayPort(TM) Adapter allows you to connect up to two DisplayPort(TM) monitors from a single Mini DisplayPort(TM) output. The JDA146 utilizes multi-stream transport (MST) protocol, supporting up to 2 displays independently at up to 4k @ 30Hz each with DP 1.2.

Description

The j5create JDA146 is a Mini DisplayPort to Dual DisplayPort adapter designed for users who need to connect two DisplayPort monitors to a compatible computer with one Mini DisplayPort output. Its Multi-Stream Transport (MST) functionality allows two displays to operate simultaneously and independently when the host graphics hardware supports the required DisplayPort 1.2 MST and HBR2 capabilities.

With support for resolutions up to 3840 x 2160 at 30Hz, the JDA146 is suitable for high-resolution productivity environments, office workstations, photography, graphic design and other applications that benefit from additional desktop space. The adapter supports extended, expansion and mirror modes, allowing users to configure their displays according to their workflow.

The JDA146 features one Mini DisplayPort male host connector and two female DisplayPort video outputs. It is USB-powered and includes a Micro USB power cable. The adapter is designed for plug-and-play use without additional driver installation, making setup straightforward on compatible systems.

System compatibility is important when using the JDA146. Independent dual-display operation requires a graphics card or video source with DisplayPort 1.2 and MST plus HBR2 support. The official specifications also state that macOS does not support MST extended mode and therefore limits the adapter to mirror mode. When connected to an older DisplayPort 1.1 or earlier video source, the adapter operates as a splitter with mirroring and resolution limitations.
