UGREEN Mini HDMI Adapter Cable Male to Female 4K 22cm – 20137

The UGREEN Mini HDMI adapter cable (model 20137) converts a Mini HDMI (Type C) port on a laptop, camcorder, camera, or tablet to a standard HDMI Type A female interface, enabling connection to a TV, HDTV, monitor, or projector. At 22 centimetres, it functions as a short, flexible pigtail rather than a full-length cable, making it an ideal bridge between a Mini HDMI device and a standard HDMI cable already in place. It suits photographers, videographers, content creators, and compact-device users who need a reliable, low-profile connection to an external display.

The 22cm length is a deliberate design choice. It reduces strain on the Mini HDMI port of the source device — a port that, on cameras and slim laptops, is particularly vulnerable to damage from rigid, heavy cables pulling at an angle. Additionally, the short flexible section absorbs movement and vibration, which matters when a camera is mounted on a tripod or rig. An extra standard HDMI male-to-male cable (sold separately) is required when connecting directly to a TV or monitor, as the female end of this adapter accepts that cable’s plug.

The adapter supports up to 4K UHD at 3840×2160 and 60Hz, transmitting at up to 10 Gbps. Furthermore, it supports Audio Return Channel (ARC), HDMI Ethernet Channel (HEC), 32-channel audio, Dolby True Audio, and 3D video, eliminating the need for a separate audio cable.

Important compatibility note: This adapter is designed for Mini HDMI (Type C) ports only — it is not compatible with Micro HDMI (Type D) ports. Verify your device’s port type before purchase.

Use Cases and Applications

Photography and Videography — Camera to Monitor

DSLRs, mirrorless cameras, and camcorders with Mini HDMI ports are routinely connected to external monitors for live view, playback review, or client preview during shoots. The UGREEN Mini HDMI adapter cable allows this connection without placing stress on the camera’s Type C port. The 22cm pigtail absorbs cable tension from a heavier standard HDMI run, which is particularly useful when the camera is mounted on a rig or cage. Compatible devices include the Nikon D3200, Nikon D810, Sony HDR-XR500, and a wide range of Canon DSLRs with Mini HDMI output.

Compact Laptops and Single-Board Computers

Slim laptops and compact computing platforms such as the Raspberry Pi Zero, Lenovo ThinkPad Yoga 12, and NUC barebones desktops use Mini HDMI rather than full-size HDMI to conserve chassis space. However, most monitors and projectors use standard HDMI inputs. The 20137 bridges this gap cleanly, connecting the device’s Mini HDMI port to any standard HDMI cable or display input. Consequently, users avoid carrying a separate dongle or adapter hub for display output.

Portable Projector and Conference Room Connections

Pico projectors and conference-room displays frequently use standard HDMI inputs. A presenter carrying a tablet or compact laptop with a Mini HDMI port can connect directly using the UGREEN Mini HDMI adapter cable paired with a standard HDMI cable already in the room. The plug-and-play design means no drivers are required, and the connection is established immediately upon plugging in.
