Display adapter Secomp S3215 — USB Type-C to DisplayPort v1.2

The Secomp S3215 is a compact display adapter that converts a USB Type-C video output (with Alt Mode support) to DisplayPort v1.2. It allows compatible laptops, tablets and smartphones to connect to external monitors, projectors and other DisplayPort-equipped displays. The adapter supports standard DisplayPort 1.2 signal transmission for high-resolution video and can be used for single-monitor connections or as part of multi-monitor setups where the host device provides a native USB-C alternate mode video output.

Advantages

The Secomp S3215 provides a direct, passive conversion from USB-C Alt Mode to DisplayPort 1.2 without the need for drivers, enabling straightforward plug-and-play operation. Its small form factor makes it portable and convenient for mobile work, meetings or travel. By using the DisplayPort 1.2 standard it supports high-resolution displays and common video features associated with that specification.

Suitable for

• Connecting a USB-C Alt Mode laptop or tablet to a DisplayPort monitor or projector
• Extending or mirroring a notebook display to an external screen
• Temporary setups for presentations, meetings or mobile workstations

When it may not be suitable

This adapter requires a host device that outputs video over USB-C using DisplayPort Alternate Mode; it will not provide video from plain USB-C ports that lack Alt Mode or from USB-A ports. It is designed for DisplayPort 1.2 signal transmission and may not support features introduced in later DisplayPort versions such as higher bandwidth modes, newer HDR signaling, or multi-stream transport configurations beyond the capabilities of DP 1.2 and the host device.

Key specifications

• Input: USB Type-C (requires DisplayPort Alternate Mode)
• Output: DisplayPort version 1.2
• Function: Video signal conversion from USB-C to DisplayPort
• Compatibility: Devices with USB-C Alt Mode video output and displays with DisplayPort input
• Form factor: Compact, portable adapter

How to use

Connect the USB Type-C plug of the Secomp S3215 to the host device's USB-C port that supports DisplayPort Alternate Mode. Plug a DisplayPort cable from the adapter’s DisplayPort connector into the monitor, projector or display. Power on the host and the display; the host operating system should detect the external display automatically and allow configuration of resolution, scaling and display mode (extend or mirror) through the system display settings.

What to consider before purchase

• Verify that your laptop, tablet or smartphone supports DisplayPort Alternate Mode over USB-C.
• Confirm that your monitor or projector accepts DisplayPort input and supports the desired resolution and refresh rate under DisplayPort 1.2.
• For higher resolutions, refresh rates or advanced HDR features, check whether a newer DisplayPort version or an active adapter is required.

Usage recommendations

Use a high-quality DisplayPort cable to ensure stable signal transmission and check host display settings after connection. For stationary multi-monitor setups, consider a docking station or active adapters if you require features beyond DisplayPort 1.2 or additional ports.
