SMUGDESK 6.6ft USB-C to DisplayPort 1.4 Cable 8K 60Hz

SKU CH-PNY2-WDFFD

Connects a USB-C device to a DisplayPort monitor at up to 8K 60 Hz or 4K 144 Hz over a 6.6 ft cable

  • 8K 60 Hz resolution via 32.4 Gbps DisplayPort 1.4 bandwidth
  • 4K 144 Hz gaming performance enabled by HBR3 and DSC 1.2 compression
  • 2K 240 Hz high-refresh support for competitive play
  • Thunderbolt 3 and 4 host compatibility through USB-C DP Alt Mode
  • 6 ft length gives flexible desk placement without signal loss

What it is

This 6.6 ft USB-C to DisplayPort 1.4 cable connects a USB-C source device to a DisplayPort monitor. It carries video using DisplayPort Alt Mode and supports resolutions up to 8K at 60 Hz, 4K at 144 Hz, and 2K at 240 Hz with HDR and DSC 1.2 compression.

Installation notes

Plug the USB-C end into a port that explicitly supports DisplayPort Alt Mode and the DisplayPort end into the display. The cable is unidirectional, so it will not work from a DisplayPort source to a USB-C monitor. No drivers are required, but the host must advertise Alt Mode capability for any signal to appear.

Who should buy it

Suits users with Thunderbolt 3 or 4 laptops, recent MacBook Pro models, or other USB-C devices that support DP Alt Mode and want high-refresh 4K or 8K 60 Hz output. Not for buyers whose USB-C ports lack video output, who need a bi-directional cable, or who must drive a USB-C monitor from a DisplayPort source.

Questions about this item

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

Check your display settings to confirm 7680x4320 resolution at 60Hz is active; the cable supports HBR3 bandwidth of 32.4Gbps and DSC 1.2 for visually lossless 8K output.

What comes in the box and do I need any extra adapters?

The package includes the 6.6ft USB-C to DisplayPort 1.4 cable only; no separate adapters are required if your source device supports DP Alt Mode over USB-C or Thunderbolt 3/4.

Which resolution and refresh rate combination should I choose for my setup?

Match your monitor and GPU capabilities: 8K at 60Hz, 5K at 60Hz, 4K up to 144Hz, or 2K up to 240Hz; the cable handles all listed modes via DP 1.4 Alt Mode.
