SKU CH-DK8K-HVNTJ

Connects a USB-C device with DP Alt Mode to a DisplayPort monitor at up to 8K 60 Hz or 4K 144 Hz with HDR over a 3.3 ft cable

  • 8K@60Hz for ultra-sharp detail via 32.4Gbps bandwidth
  • 4K@144Hz fluid gaming with DSC 1.2 compression
  • 2K@240Hz competitive speed on 3.3FT cable
  • Thunderbolt 3/4 source support with DP Alt Mode
  • 10-bit HDR colour depth for professional visuals

Signal performance

This SMUGDESK cable carries DisplayPort 1.4 signals over a USB-C connector with Thunderbolt 3 and 4 hosts. It delivers 32.4 Gbps bandwidth, enabling 8K at 60 Hz, 4K at 144 Hz and 2K at 240 Hz with HDR and 10-bit colour. DSC 1.2 compression provides visually lossless quality at the highest resolutions.

Host requirement

The cable operates only from a USB-C source that supports DisplayPort Alternate Mode. It is not bi-directional, so it cannot drive a USB-C monitor from a DisplayPort output. Compatibility is confirmed with Thunderbolt 3 and 4 laptops such as MacBook Pro 2017 and 2018 models.

Usage fit

Suited for users connecting a Thunderbolt-equipped laptop to a high-refresh DisplayPort display for gaming or creative work. Not for buyers needing a DisplayPort-to-USB-C direction, those without DP Alt Mode on their port, or anyone requiring cable lengths beyond 3.3 ft.

Highlights

Questions about this item

How long is the cable and will that length limit the 8K 60 Hz signal?

The cable is 3.3 ft long and rated for 32.4 Gbps, so the 8K 60 Hz signal is supported at this length.

What bandwidth ceiling will I hit first when running 4K at 144 Hz all day?

The 32.4 Gbps DisplayPort 1.4 link is the limiting factor; 4K 144 Hz fits within that bandwidth with DSC 1.2 compression.

Does the cable get warm or draw extra power during continuous 8K 60 Hz use?

It is a passive copper cable with no active electronics, so it produces no noticeable heat and draws no additional power beyond the source port.
