ATEN DisplayPort / HDMI / VGA Switch with HDBaseT Transmitter

The ATEN VE3912T is an HDBaseT AV transmitter that extends DisplayPort, HDMI, or VGA video signals up to 4K (4096 x 2160) over a single Cat 6/6a or ATEN 2L-2910 Cat 6 cable for distances up to 100 m. It accepts multiple input formats and provides an HDMI output, supporting HDCP 2.2, 3D, and Deep Color for compatibility with modern 4K sources and displays. The unit includes Auto Switch Mode for automatic source selection and a built-in PoH (Power over HDBaseT) capability so it can be powered from a compatible HDBaseT receiver or transmitter port, reducing the need for a separate power adapter.

Advantages

The VE3912T combines signal extension and input switching in a compact black enclosure, enabling integration of digital (DisplayPort, HDMI) and analog (VGA) sources into a single HDMI output while preserving high video quality. Compliance with HDMI specifications and HDCP 2.2 ensures broad compatibility with protected 4K content. Its 100 m transmission range over Cat 6/6a cable and low power consumption (around 8.77 W) make it suitable for professional AV setups where cable length and efficiency matter.

Suitable for

• Conference rooms and meeting spaces with multiple source types
• Lecture halls and educational environments requiring long cable runs
• Digital signage and AV installations that need 4K extension up to 100 m
• Setups that combine analog VGA and digital DisplayPort/HDMI sources

How to use

Connect your source device to one of the VE3912T inputs (DisplayPort, HDMI, or VGA) and connect the HDMI output to a local monitor if required. Use a Cat 6/6a (or ATEN 2L-2910 Cat 6) cable to connect the VE3912T HDBaseT port to a compatible HDBaseT receiver located up to 100 m away. If the receiver provides PoH, the VE3912T can draw power from the HDBaseT link; otherwise connect the supplied power adapter where applicable. The Auto Switch Mode will select a newly connected active source automatically, or you can choose the source using connected control interfaces if available.

Recommendations

For reliable 4K transmission, use shielded Cat 6/6a cable and keep cable runs within 100 m. Ensure the connected receiver or switch supports HDCP 2.2 and PoH when relying on power over HDBaseT. In mixed-source environments, test the expected output resolution on the display and, if necessary, adjust source device output settings to match the display’s capabilities.
