Overview Summary

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.

FAQ

What is the j5create JDA146 used for?

The JDA146 is used to connect up to two DisplayPort monitors to a compatible computer with a Mini DisplayPort output.

Does the JDA146 support dual 4K monitors?

Yes. It supports up to two displays at 3840 x 2160 at 30Hz each when the host system meets the required DisplayPort 1.2 MST and HBR2 specifications.

Does the JDA146 support extended desktop mode?

Yes. Extended and expansion modes are supported on compatible systems with DisplayPort 1.2 MST and HBR2 support.

Does the JDA146 work with Mac computers?

The adapter can connect to compatible Mini DisplayPort Mac systems, but the official specifications state that macOS does not support MST extended mode. On macOS, the adapter is therefore limited to mirror mode.

Does the JDA146 require USB power?

Yes. The adapter requires an external USB power source and includes a Micro USB power cable.

Does the JDA146 require drivers?

No additional driver installation is required for supported systems. The host computer and graphics hardware must still meet the required DisplayPort and MST specifications.

What graphics specification is required for independent dual displays?

The graphics card or video source must support DisplayPort 1.2 with Multi-Stream Transport (MST) and High Bit Rate 2 (HBR2) for independent dual-display output.

Can the JDA146 mirror the same image on two monitors?

Yes. Mirror mode is supported. The adapter also supports extended and expansion display modes on compatible systems.

What ports are available on the JDA146?

The adapter has one Mini DisplayPort male host connector, two female DisplayPort video outputs and one Micro USB power connection.
