Product information

Description

The C2G Universal 4K HDMI Dongle Adapter Ring with Mini DisplayPort, DisplayPort, and USB-C in Black provides a practical solution for connecting modern laptops and tablets to a central display. Designed for collaborative environments such as conference rooms, classrooms, and huddle spaces, this accessory ensures that participants can readily connect their devices regardless of the video output port they use. Featuring color-coded connections and gold-plated contacts, it maintains reliable signal transmission and supports clear visual output for presentations and meetings.

Advantages

This adapter ring consolidates multiple common video connections into a single organized unit that attaches directly to an existing HDMI cable. The inclusion of color-coded rings allows users to quickly identify the correct adapter for their specific device, minimizing delays during meetings. The flexible dongle design reduces physical strain on device ports and prevents laptops from shifting on tables during connection. Additionally, the integrated pull tab makes it easy to retrieve the adapters when needed, keeping workspaces tidy and equipment secure.

Suitable for

Connecting laptops with USB-C, DisplayPort, or Mini DisplayPort to an HDMI display
Conference rooms and collaborative meeting spaces
Educational environments such as classrooms and lecture halls
Shared workspaces requiring multi-device display compatibility

When it may not be suitable

This adapter ring is not designed for permanent fixed-wall installations where cables are routed behind drywall without access to the display cable. It may also not be suitable for devices that lack USB-C, DisplayPort, or Mini DisplayPort video output capabilities.

Key specifications

Maximum resolution: 3840 x 2160 pixels
Connector 1: HDMI, female
Connector 2: Mini DisplayPort, DisplayPort, USB-C, male
Connector contact plating: Gold
Product color: Black

How to use

To set up the adapter ring, attach the universal cable mount directly to the existing HDMI display cable using the included installation tools. Position the adapters so they slide freely along the cable for easy access during presentations. When connecting a device, select the appropriate color-coded adapter matching your laptop or tablet port—Mini DisplayPort, standard DisplayPort, or USB-C—and plug the male connector into your device. Ensure the female end is securely joined with the room's HDMI cable to establish the video signal.

What to consider before purchase

Verify that your room display uses a standard HDMI input cable
Check that your laptops or tablets feature USB-C, DisplayPort, or Mini DisplayPort video outputs
Ensure the physical diameter of your existing HDMI cable is compatible with the mounting accessories

Usage recommendations: Secure the adapter ring to the primary HDMI display cable in environments where multiple users frequently switch devices. Regularly check that the gold-plated connector contacts remain clean and free of dust to maintain optimal signal transmission and 4K video resolution performance.
