DeLOCK DisplayPort 1.4 splitter, 1 x DisplayPort → 3 x HDMI, MST (87770)

The DeLOCK 87770 receives a DisplayPort signal from a PC or laptop and distributes it to three HDMI displays. As an MST (Multi-Stream Transport) hub compatible with DisplayPort 1.4, it enables using a single DisplayPort output to drive up to three HDMI monitors at high resolution. The compact device measures 105 × 43 × 14 mm, is made of durable black plastic and requires a 5 V AC power input.

Advantages

The splitter supports DisplayPort MST with individual monitor control in Windows, allowing extended desktop configurations or combining screens into one large desktop. Thanks to DisplayPort 1.4 bandwidth it can handle three displays at up to 3840 × 2160 pixels each. The unit is small and lightweight with a short integrated DisplayPort cable (approx. 0.125 m) and a universal HDMI output arrangement for easy installation.

How to use

Connect the integrated DisplayPort plug to the DisplayPort output of your PC or laptop, then attach up to three HDMI cables from the splitter’s HDMI outputs to the monitors. Provide power to the unit using the specified 5 V supply if required. In Windows, configure display settings in Display Settings to arrange monitors, set extended desktop or mirror modes, and adjust resolution per monitor. Ensure the graphics card and DisplayPort output support MST and the combined bandwidth for the desired resolutions.

Recommendations

Use short, high-quality HDMI cables and verify that the host device’s DisplayPort output supports MST and sufficient bandwidth for three 4K displays. For best results with 4K @60 Hz across multiple screens, confirm graphics card capabilities and cable specifications.
