UGREEN 30841 1.5 m USB-C to HDMI Cable, 4K 30 Hz

Overview

The UGREEN 30841 is a 1.5 m cable with a USB-C plug at one end and an HDMI plug at the other, for showing a USB-C laptop or tablet screen on an HDMI TV, monitor or projector without a separate adapter or HDMI lead. It supports up to 3840 x 2160 at 30 Hz with a compatible source and display, and carries HDMI audio with the video. The signal flows one way, from the USB-C device to the HDMI display, and the USB-C port must support video output.

Is it right for you?

• It suits documents, presentations and video from a laptop or tablet whose USB-C port supports DisplayPort Alternate Mode, Thunderbolt 3 or 4, or compatible USB4 video output.
• Plan around 4K at 30 Hz. 1080p modes may run at higher refresh rates when the source and display agree, but this version is not presented as a 4K at 60 Hz cable.
• It works one way only: USB-C source to HDMI display. It cannot connect an HDMI source to a USB-C monitor.
• Many USB-C phones and tablets support charging and data but not wired display output; check the device specification for DisplayPort Alt Mode or desktop display support.

Key features

• Converts a USB-C DisplayPort video signal to HDMI, up to 3840 x 2160 at 30 Hz.
• Mirror and extended desktop modes when the host operating system allows them.
• Carries compatible HDMI audio together with the video.
• 1.5 m cable with ABS connector housings, gold-plated contacts and shielded construction.
• Plug-and-play: no separate graphics driver.

What else you need

A source with a USB-C port that supports DisplayPort Alternate Mode, Thunderbolt 3 or 4, or compatible USB4 video, and a display with an HDMI input. No driver or power supply is needed. It does not charge the device and does not provide USB data, a hub, Ethernet or memory card access.

Installation

No installer is needed. Plug the USB-C end into the laptop or tablet and the HDMI end into the display, select the HDMI input and choose mirror or extend in the display settings. Check that 1.5 m reaches without straining either connector.

Before you buy

• The USB-C port must explicitly support DisplayPort Alt Mode, Thunderbolt video or compatible USB4 display output.
• Direction is USB-C source to HDMI display only.
• It does not charge the connected computer, tablet or phone.
• If only 1080p appears, the weakest part of the path sets the mode: check the source graphics capability, the operating system display settings and the HDMI input. If the display stays blank after sleep, unplug and reconnect or reselect the input, then update the graphics software if it recurs.
