Splitter DeLOCK USB Type-C DP Alt Mode σε 3 x HDMI MST 4K 60 Hz

The DeLOCK USB Type-C Splitter DP Alt Mode to 3 x HDMI MST 4K 60 Hz enables connection of three HDMI displays to a computer with a USB-C port that supports DisplayPort alternate mode. It functions as a Multi-Stream Transport (MST) hub and allows all three monitors to be operated simultaneously in extended desktop configurations. The compact black housing measures 36 mm x 98 mm x 12 mm and supports 4K resolution at 60 Hz on each connected display.

Advantages

This splitter uses DisplayPort 1.4 bandwidth to deliver high-resolution output and supports HDCP 1.4/2.2 for protected content. As an MST device it lets Windows control each connected monitor individually or combine them into a single large display. The compact form factor and USB-C single-cable connection simplify multi-monitor setups.

Suitable for

• Office work requiring multiple screens (spreadsheets, documents, email)
• Software development and testing with multi-window layouts
• Creative workflows that benefit from extended desktop space (design, video editing)
