  • Drives 8K at 60 Hz with 32.4 Gbps bandwidth
  • Delivers 4K at 144 Hz for fluid gaming motion

USB-C to DisplayPort 1.4 Cable

The SMUGDESK cable connects a USB-C source that supports DisplayPort Alt Mode to a DisplayPort display. It serves laptop owners, tablet users and desktop builders who need a single-cable link for high-resolution monitors. The six-point-six-foot length suits typical desk setups without excess slack.

32.4 Gbps HBR3 bandwidth and DSC 1.2

The cable meets the VESA DisplayPort 1.4 specification with High Bit Rate 3 signalling and Display Stream Compression 1.2 for visually lossless 3:1 ratios. It carries 32-bit audio, Dynamic HDR, HDCP 2.2 and 1.4, and Windows MST for multi-stream transport. Backward compatibility covers DisplayPort 1.3, 1.2 and 1.1 devices. Thunderbolt 4 and 3 hosts work without adapters or drivers.

Upgrades older DisplayPort or HDMI links

The jump is worth it when moving from a connection limited to 4K at 60 Hz or 2K at 144 Hz to 8K at 60 Hz, 4K at 144 Hz or 2K at 240 Hz. It replaces separate audio cables and reduces flicker or audio clipping seen on lower-bandwidth links. Buyers who need more than four 1080p streams or who lack a USB-C port with Alt Mode will not be served by this cable.

Questions about this item

What does the 32.4 Gbps bandwidth of this DisplayPort 1.4 cable actually cap in practice?

The cable delivers up to 8K at 60 Hz, 5K at 60 Hz, 4K at 144 Hz and 2K at 240 Hz using HBR3 and DSC 1.2 for visually lossless compression.

What physical connectors and length does this 6.6 ft cable need to fit my setup?

It has a USB-C plug with DP Alt Mode on one end and a standard DisplayPort plug on the other; the cable runs 6.6 ft with no external power adapter required.

How do I install this cable, and what step do people often get wrong?

Plug the USB-C end into a Thunderbolt 4, Thunderbolt 3 or USB-C port that supports DP Alt Mode, then connect the DP end to the monitor; the host port must explicitly support video output or no signal appears.
