BENFEI 000318grey USB-C to HDMI Adapter, 4K at 60 Hz, Grey

Connect a USB-C laptop to a projector for a presentation, or send a compatible phone or computer’s picture to an HDMI monitor or TV. The BENFEI 000318grey adapter provides a direct link for display output, with support for resolutions up to 3840 × 2160 at 60 Hz for a detailed picture on a compatible screen.

Its compact design is easy to tuck into a bag or pocket, making it a practical accessory for a desk setup, meeting room or travel kit. The adapter is listed as compatible with devices including iPhone 15 Pro/Max, MacBook Pro and Air, iPad Pro, iMac, Samsung S23 and Dell XPS models.

Key takeaways

This USB-C to HDMI adapter converts a digital USB-C signal to HDMI through a built-in IC chip. It supports up to 4K at 60 Hz, as well as 4K at 30 Hz, 2K at 144 Hz and common lower resolutions. The display mode you can use depends on the connected device and screen supporting it.

For everyday work, that means you can connect a compatible computer to a larger monitor for more viewing space, or use an HDMI projector when presenting slides. For home viewing, it offers a simple way to connect a compatible device to an HDMI-equipped TV. If your goal is one display connection, this focused adapter is a straightforward alternative to carrying a larger multiport hub.

The USB-C connector is plated to resist corrosion and abrasion, and its moulded strain relief is designed to support cable durability. Its grey finish gives it a neutral look alongside common laptop and desktop setups.

How to use it

Connect the adapter’s USB-C end to a device with a USB-C port, then connect an HDMI cable from the adapter to the monitor, projector or TV. The source device must support USB Type-C DisplayPort Alt Mode for video output. This is a key compatibility check when choosing a USB-C display adapter, a USB-C port alone does not establish that the device can send video.

BENFEI lists compatibility across a range of computers and mobile devices, including MacBook, Chromebook, Dell XPS, HP Spectre, selected Samsung devices and iPhone 15 Pro/Max. Check that the specific device supports DisplayPort Alt Mode and that the display accepts HDMI input. For the clearest setup, select a resolution and refresh rate supported by both connected devices.

Practical tips

For a presentation, connect the laptop to the room’s HDMI projector before opening your slides, then set the display arrangement on the computer to suit the room. At a desk, use the same connection to add an HDMI monitor to a compatible laptop. For shared viewing, connect a compatible phone or tablet to an HDMI TV and use the display settings on the source device to choose how its picture appears.

The adapter is especially useful when portability matters and the task is specifically USB-C-to-HDMI display output. Its small format takes up little space in a work bag, while support for high-resolution output makes it suitable for compatible 4K displays as well as lower-resolution screens.

Final verdict

Choose the BENFEI 000318grey for a compact, direct connection between a video-capable USB-C device and an HDMI display. Its 4K-at-60-Hz support, broad listed device compatibility and portable design make it a useful fit for presentations, desk displays and connecting compatible devices to a TV.
