USB-C DisplayPort to Dual HDMI Adapter ITEC C31TRIPLEVIDEODPPRO 4K 60Hz, 100W Power Delivery

ITEC C31TRIPLEVIDEODPPRO is a USB-C DisplayPort Alt Mode adapter that converts a single USB-C port into two HDMI outputs while passing power to a connected host. The adapter supports dual-display configurations with resolutions up to 4K at 60Hz on compatible monitors and includes Power Delivery passthrough up to 100W to charge laptops or power USB-C devices during use. The compact design and plug-and-play operation make it suitable for workstations, meeting rooms and mobile setups where extra HDMI outputs are required.

Advantages

The adapter enables simultaneous output to two HDMI displays using a single USB-C port, maintaining high-resolution video at up to 4K 60Hz where the host and displays support it. Integrated Power Delivery passthrough up to 100W allows the host device to be charged while external displays are connected, reducing the need for additional power adapters. The unit uses DisplayPort Alt Mode for reliable video transmission and requires no additional drivers on most modern operating systems, providing straightforward plug-and-play connectivity.

Suitable for

• Extending a laptop desktop to two external HDMI monitors for multitasking
• Mirroring presentations to one or two screens in meeting rooms
• Connecting a laptop to TVs or projectors for media playback at up to 4K 60Hz
• Mobile work setups where a single USB-C port must provide video and charging simultaneously

Key specifications

• Connection: USB-C (DisplayPort Alt Mode) to dual HDMI outputs
• Maximum video resolution: up to 4K (3840×2160) at 60Hz on compatible displays
• Power Delivery passthrough: up to 100W to charge the connected host
• Supports dual-display configurations: extend or mirror modes depending on host GPU and OS
• Plug-and-play operation on devices supporting DisplayPort Alt Mode

How to use

Connect the adapter to a USB-C port on a compatible laptop or device that supports DisplayPort Alt Mode. Attach HDMI cables from the adapter’s HDMI outputs to external displays or TVs. If charging is required, connect the laptop charger to the adapter’s USB-C power input; the adapter will pass power through to the host up to the supported 100W. Configure display arrangement (extend or mirror) in the operating system display settings as needed. No additional drivers are typically required on modern operating systems, but check system specifications to confirm DisplayPort Alt Mode support.

Recommendations

For optimal results, use high-quality HDMI cables rated for 4K 60Hz, update the host device display drivers where applicable, and verify that the laptop’s USB-C port supports DisplayPort Alt Mode and sufficient power delivery. When using two high-resolution displays simultaneously, consult the host GPU and OS limitations as bandwidth may constrain maximum resolution or refresh rate on both outputs.
