Jansicotek DP 1.4 Splitter 1x3
The Jansicotek DisplayPort 1.4 splitter takes a single DP source and distributes it to three DP 1.4 displays. It operates in mirror mode for identical output or MST mode for independent screens. The host requires the included USB-A to Micro-B cable for power. It is intended for users with a discrete graphics card; integrated graphics may encounter compatibility limits.
Passive operation thermals noise power
The unit has no active cooling, so it runs silently and adds negligible heat to a workstation. Power is drawn only from the external USB connection, keeping system load minimal. Typical desktop use at 4K@60Hz or 1440p@144Hz remains stable without thermal throttling. Bandwidth capacity is rated at 32.4 Gbps across the link.
Sustained load MST multi-monitor behaviour
Under continuous MST expansion, a single active port can maintain 8K@30Hz or 4K@144Hz while all three ports simultaneously deliver 4K@60Hz. Apple systems restrict MST to one extended display due to OS limitations. The splitter supports DP 1.0 through 1.4 signalling, 3D formats, and refresh rates up to 165Hz at 1440p without signal degradation over extended sessions.

Questions about this item
How do I install the Jansicotek 3-port DP 1.4 splitter and what step is often missed?
Connect the single DisplayPort 1.4 input to your source, attach up to three DisplayPort 1.4 displays to the outputs, then plug the included USB-A to Micro-B cable into a powered USB port to supply the splitter — forgetting this power cable is the most common mistake.
What maintenance or replacement will the Jansicotek DP 1.4 splitter need over time?
The unit has no user-serviceable parts or consumables; if the USB power cable or any DisplayPort cable becomes damaged, replace that cable — the splitter itself requires no scheduled maintenance.
What is the first resolution limit I will hit when driving three displays simultaneously with this splitter?
In MST expansion mode all three outputs are capped at 3840x2160 @ 60 Hz, so 4K 60 Hz is the ceiling before bandwidth or stream limits appear.
