UGREEN 70444 USB-C HDMI Adapter – 4K@60Hz, Male to Female (Aluminium)

The UGREEN 70444 is a compact USB-C to HDMI adapter that converts a USB-C or Thunderbolt 3/4 port into an HDMI 2.0 female socket, allowing users to connect any standard HDMI cable to reach a monitor, television, or projector. Unlike a fixed-length cable, this adapter works with the user’s existing HDMI cable, making it a flexible choice for desk setups and travel use. Consequently, it suits MacBook users, iPad Pro owners, and professionals who need reliable 4K@60Hz display output without carrying an additional dedicated cable.

How This Adapter Differs from the UGREEN MM121 Cable

The UGREEN MM121 (30841) is a fixed-length male-to-male cable (USB-C plug to HDMI plug, 1.5m) outputting at 4K@30Hz. The UGREEN 70444 is a compact male-to-female adapter dongle outputting at 4K@60Hz, which requires a separate HDMI cable to connect to the display. The 70444 is the better choice when a higher refresh rate matters or when using an existing HDMI cable of a specific length.

Use Cases & Applications

Office and Conference Room Presentations

Connecting a MacBook or Windows laptop to a conference room projector or external monitor via the 70444 takes seconds — insert the adapter into the USB-C port, connect the room’s HDMI cable, and the display activates automatically. Extended mode allows the laptop screen to continue showing notes or speaker view while the presentation runs on the external display. Furthermore, the compact aluminium body makes the adapter a low-profile fit alongside a laptop port without obstructing adjacent connections.

Home Entertainment and 4K Streaming

The 70444’s 4K@60Hz output makes it well suited for connecting a laptop or tablet to a 4K television for video streaming. At 60Hz, fast-moving content — sports, action sequences, and high-frame-rate video — renders without the motion judder that occurs at 30Hz. Additionally, 7.1 surround audio passes through the HDMI connection simultaneously, removing the need for a separate audio output cable.

Samsung DeX Mobile Workstation

Samsung Galaxy smartphones and tablets with DeX support output a full desktop-style interface through the 70444 when paired with an HDMI display. This transforms a compatible handset into a functional workstation for documents, email, and web browsing — particularly useful in hotel rooms or temporary workspaces where only a television’s HDMI port is available. Note that the device must support DP Alt Mode natively for DeX over HDMI to function.

Important Notes

• DisplayPort Alternate Mode is required on the source USB-C device. The adapter does not function with USB-C ports carrying power or data only — confirm device compatibility before purchase.
• Charging is not supported. This variant of the 70444 carries video and audio signals only. A separate charging connection is required during use.
• Signal is unidirectional — USB-C source to HDMI display only.
• 4K@60Hz requires compatible hardware on both source and display. Devices or monitors limited to DisplayPort 1.2 will output at a lower resolution or refresh rate.
