Acer OCB255 USB-C to HDMI 2.1 Cable, 2m, 8K@60Hz, Braided

Connect a USB-C laptop, tablet or phone to an HDMI television or monitor for a larger view of films, games or work. The Acer OCB255 cable is 2m long, giving you room to position your device while it is connected to the screen.

Its HDMI 2.1 support reaches up to 8K@60Hz and includes 4K options up to 240Hz. That makes it useful for compatible home cinema and gaming setups, as well as mirroring or extending a workspace.

A braided nylon cable and aluminium housing bring practical details to a connection you may use regularly. Choose it when you want a direct USB-C-to-HDMI link rather than a separate adapter and HDMI cable.

How to use it

Connect the USB-C end to a compatible source device and the HDMI end to a television or monitor. The cable works in that direction only: it sends video from USB-C to HDMI, rather than connecting an HDMI source to a USB-C display. Check that your source has USB-C video output and that the screen has an HDMI input.

For a desk setup, use the display in mirror mode to show the same content on both screens, or extended mode to spread tasks across them. It can also be used with Apple Clamshell and Samsung DeX modes. At home, connect a compatible device to an HDMI television for films or gaming, with the 2m length helping to bridge the space between device and screen.

Pros

The range of supported resolutions and refresh rates makes the cable suitable for more than basic screen mirroring. It supports up to 8K@60Hz and lists 4K@240Hz, 144Hz, 120Hz and 60Hz options, so compatible equipment can be used for detailed video or high-refresh-rate gaming. The source device and display both need to support the chosen mode.

A 48Gbps data transfer rate, Dynamic HDR and HDCP 2.3 support are also specified. For home cinema, the cable supports eARC and formats including Dolby Atmos and Dolby Vision. Buyers have also praised its functionality and build quality, with one noting use with a 100Hz monitor, these are individual impressions rather than a guarantee of results with every setup.

Key points

The OCB255 is a 2m USB-C to HDMI 2.1 cable with a braided nylon exterior and aluminium housing. It weighs 60 grams, making it straightforward to move between a home desk and an entertainment setup. Its compact, non-slip design is intended to make plugging and unplugging easier.

The listed compatible devices include MacBook, iPad, iPhone 15, 16 and 17, Samsung Galaxy S24, S25 and S26, Google Pixel 10, Surface devices, Dell XPS, Steam Deck and ROG Ally. Compatibility depends on the device supporting video output over USB-C. The cable also supports audio transmission including DTS, DSD and LPCM 7.1/5.1.

Before you decide

Can I connect an HDMI device to a USB-C monitor with this cable? No. It is unidirectional, carrying video from a USB-C source to an HDMI display. It is not intended for reverse use or for connecting a USB-C display.

What is needed to use 8K output? Both the source device and the monitor must support 8K. On Mac, macOS limitations mean the cable cannot reach 8K output.

Can I mirror or extend my display? Yes. Mirror and extended display modes are supported, alongside Apple Clamshell and Samsung DeX modes. The available setup can depend on the connected device and its software.

Final verdict

For connecting a compatible USB-C device to an HDMI screen, the Acer OCB255 combines a useful 2m reach with support for high-resolution video, high refresh rates and home cinema audio features. Its braided construction and multiple display modes make it a practical fit for switching between desk work, gaming and viewing on a larger screen.
