UGREEN USB-C Male to HDMI Male Cable 1.5m – White – MM121

The UGREEN MM121 is a 1.5-meter USB-C to HDMI cable that directly connects USB-C devices to HDMI displays and projectors with support for 4K resolution at 60Hz. This integrated cable design features a white braided exterior with aluminum alloy connectors, making it ideal for students presenting from MacBooks or tablets and business professionals requiring reliable video output without the bulk of separate adapters and cables. The plug-and-play operation eliminates setup complexity during time-sensitive presentations.

Key Features & Benefits

• True 4K at 60Hz Support: Transmits video at 3840×2160 resolution with a smooth 60Hz refresh rate, which means your presentations, spreadsheets, and video content display with exceptional clarity and fluid motion instead of the choppy 30Hz output common in cheaper cables.
• Direct Cable Connection: Eliminates the adapter-plus-cable setup by integrating both functions into a single cable, so you reduce points of failure, desk clutter, and the frustration of forgetting one component when traveling to presentations or meetings.
• 1.5-Meter Optimal Length: Spans 4.92 feet—long enough to comfortably present while standing several feet from a projector or to route from a laptop on your desk to a wall-mounted monitor without excessive cable loops creating visual clutter.
• Premium White Braided Design: Features durable nylon braiding that resists tangling and matches the aesthetic of silver and white laptops like MacBooks, while the white color makes the cable easy to locate in bags and stands out positively in professional presentation environments.
• Universal USB-C Compatibility: Works with any device featuring USB-C ports with video output capability including MacBook Pro/Air, iPad Pro, Dell XPS, Surface devices, Samsung Galaxy phones, and Chromebooks without requiring driver installation or configuration.

Use Cases & Applications

For Students: University students presenting research projects or group assignments can connect MacBooks or iPad Pros to classroom projectors with a single cable without fumbling with adapters. The white color matches Apple device aesthetics while remaining visible in dimly lit lecture halls. Engineering students demonstrating software simulations or architecture students presenting CAD models benefit from the 4K resolution that displays fine details clearly. The 1.5-meter length allows comfortable movement during presentations without being tethered directly to the projector.

For Business Presentations: Sales professionals and consultants can confidently present at client offices by simply plugging their USB-C laptop into the conference room’s HDMI display. The cable’s reliability eliminates the anxiety of adapter compatibility issues during high-stakes pitches. Corporate trainers conducting workshops appreciate the quick setup—arrive, connect one cable, and begin presenting immediately. The white braided exterior projects a clean, professional appearance when cables are visible during presentations.

For Remote Work & Home Offices: Remote professionals can transform USB-C laptops into desktop workstations by connecting to external HDMI monitors for expanded screen real estate. The 4K at 60Hz support ensures text remains sharp and scrolling stays smooth during document editing or spreadsheet work. The cable length accommodates typical desk arrangements where monitors sit on stands or arms at comfortable viewing distances from the laptop.

For Content Consumption: Students or professionals can connect tablets or laptops to home TVs for streaming movies, presentations, or photo slideshows during family gatherings. The HDR10 support enhances video quality when watching compatible content from Netflix, Disney+, or Amazon Prime. The audio pass-through eliminates the need for separate audio cables when the TV handles sound output.

For Mobile Device Mirroring: Samsung Galaxy users can leverage DeX mode to transform their phones into desktop-like experiences on HDMI monitors or TVs. Photographers can display portfolio work from tablets during client meetings by connecting to conference room displays. The cable enables impromptu presentations when only a smartphone and display are available.

For Gaming & Entertainment: Nintendo Switch owners can connect their consoles to hotel TVs or friend’s displays using this cable instead of the bulky dock. Mobile gamers with USB-C phones can mirror gameplay to larger screens for better viewing experiences or demonstrations. The 60Hz refresh rate provides smooth motion during gameplay without the stuttering common at 30Hz.

For Educational Technology: Teachers using iPads or USB-C Chromebooks can display lesson materials, educational apps, or student work on classroom projectors or interactive whiteboards. The single-cable solution simplifies classroom AV setups compared to managing multiple adapters and cables. Distance learning instructors can route their tablet screens to capture cards for higher-quality streaming compared to built-in webcams.

The UGREEN MM121 provides straightforward USB-C to HDMI connectivity with minimal complexity. However, verify your device’s USB-C port supports video output before purchasing—some budget laptops and older Android phones have USB-C ports limited to charging and data transfer without DisplayPort Alternate Mode. You can usually confirm video capability by checking if your manufacturer’s specifications mention “video output” or “DisplayPort Alt Mode” for the USB-C port.

The 1.5-meter length works excellently for most presentation and desktop scenarios, but measure your specific needs if connecting devices at greater distances—conference rooms with ceiling-mounted projectors may require longer cables. The white color beautifully complements silver and white devices but may show dirt or discoloration over time with heavy use in dusty environments or frequent handling. The nylon braiding resists staining better than solid white rubber, but occasional cleaning maintains the aesthetic appeal.

This is a unidirectional cable designed for USB-C sources to HDMI displays only—you cannot use it to connect HDMI sources to USB-C displays. The cable does not support audio return channel (ARC), so TVs cannot send audio back to the source device through this connection. For video conferencing setups requiring bidirectional audio, use separate audio cables or Bluetooth connections.

The 4K at 60Hz capability requires that both your source device and display support this specification. Some older USB-C devices max out at 4K 30Hz or 1080p 60Hz—check your device specifications for its maximum video output capabilities. When connecting to 4K displays, ensure your device’s graphics settings are configured for 60Hz refresh rate rather than defaulting to 30Hz, as some systems default to lower refresh rates to conserve battery power.

The gold-plated connectors resist corrosion, but avoid excessive force during insertion—USB-C and HDMI ports should connect smoothly without requiring significant pressure. If connections feel difficult, verify proper orientation and check for debris in ports. The triple-shielding construction minimizes electromagnetic interference from nearby Wi-Fi routers, phones, or other electronics, ensuring stable video signals without visual artifacts or dropouts during critical presentations.
