SMUGDESK

SMUGDESK DisplayPort 2.1 Cable 3.3FT 16K 80Gbps

SKU CH-Z4G5-ENP9X

A 3.3 ft DisplayPort 2.1 cable supporting 16K@60 Hz, 8K@120 Hz and 4K@240 Hz with 80 Gbps bandwidth, HDR10 and DSC 1.2a

  • Supports 80Gbps bandwidth for 16K 60Hz and 4K 240Hz gaming
  • 16K at 60Hz with DSC plus 8K at 120Hz and 4K at 240Hz 165Hz 144Hz
  • Works with FreeSync and G-Sync on 3090 4090 7900 XTX graphics cards
  • Double nylon braided jacket resists wear and stays flexible
  • Backwards compatible with DisplayPort 2.0 and 1.4

Cable specification

This SMUGDESK DisplayPort 2.1 cable carries an 80 Gbps signal over a 3.3 ft length. It meets the VESA standard for UHBR20 and supports DSC 1.2a, HDCP 2.2 and HDR10. The link is backward compatible with DP 2.0, 1.4 and 1.2.

Resolution and refresh targets

The cable validates 16K at 60 Hz, 10K at 60 Hz, 8K at 120 Hz, 4K at 240 Hz, 165 Hz and 144 Hz, and 2K at 360 Hz. Variable-refresh technologies such as FreeSync and G-Sync pass through without extra configuration. Buyers whose monitor or GPU cannot drive these modes will not see the advertised rates.

Deciding bandwidth figure

The single number that determines fit is the 80 Gbps certified throughput. If the source and sink both implement UHBR20 the link will deliver the full resolution and refresh combinations listed; otherwise the connection falls back to the highest mutually supported rate.

Questions about this item

How much bandwidth does the cable actually deliver during a long gaming session?

The cable is rated for 80Gbps and meets the VESA DisplayPort 2.1 specification, so it maintains full bandwidth without signal loss over the 3.3FT length.

Does the cable or its connectors get hot when driving 4K at 240Hz all day?

The supplier notes that DisplayPort 2.1 allows the monitor to work efficiently while limiting power consumption, which reduces heat compared with DP 1.4.

What must my graphics card and monitor support for this cable to work at 16K 60Hz?

Both the source and the display need DisplayPort 2.1 ports with DSC 1.2a support; the cable is backwards compatible with DP 2.0, 1.4 and 1.2 for lower resolutions.
