C2G Universal 4K HDMI Dongle Adapter Ring Mini DisplayPort DisplayPort USB-C

The C2G Universal 4K HDMI Dongle Adapter Ring provides a compact, practical solution for connecting laptops, tablets and other devices to an in-room HDMI display. The kit includes color-coded dongle-style adapters for HDMI to Mini DisplayPort, DisplayPort and USB-C, supports up to 4K video resolution and features gold-plated contacts. A universal cable mount, integrated pull tab and included installation tools keep adapters accessible and reduce strain on the HDMI cable.

Advantages

The dongle-style design offers flexible placement when connecting thin or lightweight laptops so the host device sits flat on the table. Color-coded bands on each adapter help quickly identify the correct connector, while the integrated pull tab provides an easy grip and can be customized for organizational branding (minimum order quantities apply). The universal cable mount slides along the HDMI lead to keep adapters within reach and out of the way, and an optional stopper prevents them from sliding too far down cables 5–10 mm in diameter. Gold-plated contacts ensure reliable signal transfer for high-quality 4K video output.

Suitable for

• Conference rooms and huddle spaces
• Lecture halls and classrooms
• Meeting rooms with shared displays
• Portable setups and BYOD (bring your own device) environments

How to use

Attach the universal cable mount to the room’s HDMI cable, slide the adapter ring into position and select the color-coded dongle that matches the presenter’s device connector (Mini DisplayPort, DisplayPort or USB-C). Plug the dongle into the presenter’s device and connect the HDMI end to the in-room display. Use the integrated pull tab to remove adapters easily when finished. If using the optional stopper, install the correct stopper insert for the HDMI cable diameter using the included HDMI Cable Gauge Tool.

Recommendations

For reliable 4K video performance, ensure the in-room HDMI cable and connected devices support the desired resolution and refresh rate. Keep the dongles stored on the mount when not in use to prevent loss and reduce strain on the HDMI cable; follow any custom pull-tab ordering requirements if branding is required.
