  • Supports 8K at 60 Hz for ultra-sharp detail
  • Delivers 4K at 144 Hz for smooth gaming motion

8K USB-C to DisplayPort Cable

This 6.6 ft cable connects a Thunderbolt 4 or Thunderbolt 3 USB-C source to a DisplayPort 1.4 display. It delivers up to 8K at 60 Hz, 4K at 144 Hz and 2K at 240 Hz with 32.4 Gbps bandwidth, 10-bit colour and DSC 1.2 compression for visually lossless quality. The host device must support USB-C DP Alt Mode for video output.

Installation and Common Issues

Plug the USB-C end into a compatible Thunderbolt 4 or Thunderbolt 3 port and the DisplayPort end into the monitor; no drivers or adapters are required. The connection is backwards compatible with DisplayPort 1.3, 1.2 and 1.1. Problems usually arise when the source port lacks DP Alt Mode, when the cable is used with a plain USB-C port that carries only data, or when MacBook clamshell mode is attempted without external power.

Who This Suits and Who Should Look Elsewhere

Ideal for users with Thunderbolt 4 or Thunderbolt 3 laptops such as recent MacBook Pro, Mac Studio, Dell XPS or iPad Pro models who need high-refresh 4K gaming or 8K creative work on a single DisplayPort display. Not suitable for buyers whose USB-C ports do not support video output, for setups requiring legacy VGA, DVI or HDMI inputs, or for anyone needing a longer run than the supplied 6.6 ft length.

Questions about this item

How can I verify the cable is delivering 8K at 60 Hz after connecting it?

The monitor’s on-screen display should show 7680x4320 at 60 Hz and the OS graphics settings will report 10-bit colour with HDR active.

What comes in the box and is a separate power adapter required?

Only the 6.6 ft USB-C to DisplayPort cable is included; no external power adapter is needed because the cable draws power from the Thunderbolt 4/3 source port.

Should I choose this 6.6 ft version or a shorter one for 4K 144 Hz gaming?

The 6.6 ft length supports the full 32.4 Gbps bandwidth required for 4K at 144 Hz, so this version is suitable; a shorter cable would not provide higher performance.
