sweguard 20FT USB-C to HDMI Cable, 4K at 30 Hz, Nylon, Tangle-Free

Connect a compatible laptop, tablet or cell phone to an HDMI-equipped TV, monitor or projector for a larger view of presentations, movies, games and photos. This 20-foot sweguard USB-C to HDMI cable supports resolutions up to 4K at 30 Hz, giving you room to position your device and display where they work best.

Its nylon exterior is designed to resist tangling and everyday wear, while plug-and-play setup keeps the connection straightforward. Use it for work presentations or to enjoy content on a larger screen at home.

What matters most

The cable connects a USB-C source directly to an HDMI display, with no additional software required. It supports up to 4K at 30 Hz and is also compatible with 1080p, 1080i and 720p output. Mirroring and extended display modes are supported, making the cable useful for presenting a laptop screen, arranging a work display or sharing photos and video on a TV.

For video output, the USB-C port on the source device must support DisplayPort Alternate Mode. Compatible examples listed for this cable include MacBook models, iPad Pro, selected iPhone Pro models, Samsung Galaxy devices, Surface and Dell laptops. The 20-foot length also gives you more flexibility to place a device away from the display than a short connector or adapter allows. The nylon outer material and tangle-free design help keep the cable manageable between uses.

Best use cases

For a presentation, connect a compatible USB-C laptop to an HDMI projector and show slides on the larger screen. At home, connect a supported phone or tablet to an HDMI-equipped TV to view video, games or photo albums. It can also serve as a direct link between a computer and a monitor for a desk setup, with extended mode available when you want screen space beyond mirroring.

This is a video connection, not a charging cable. It suits setups where the device can output video over USB-C and the display accepts HDMI. If choosing between wireless casting and a wired connection, this cable provides a direct physical link and avoids setting up an additional wireless connection.

How to use it

Connect the USB-C end to a compatible source device and the HDMI end to the TV, monitor or projector. Select the relevant HDMI input on the display, then choose mirroring or extended mode on the source as needed. No driver or extra software is required. For Samsung phones that use DeX, enable DeX mode to use that display experience. Check that the device’s USB-C port supports DisplayPort Alternate Mode before relying on it for video output, a USB-C connector alone does not guarantee that feature.
