Black DisplayPort 2.1 cable with textured connectors, ten feet long

SMUGDESK

SMUGDESK DisplayPort 2.1 cable 10ft 40Gbps 8K@60Hz 4K@144Hz 2K@240Hz HDR10 HBR10

SKU CH-P19A-6Z0N7

Connects graphics cards to monitors at 8K 60 Hz, 4K 144 Hz or 2K 240 Hz with 40 Gbps bandwidth, HDR10 and 32-channel audio

  • 8K at 60 Hz resolution delivered by 40 Gbps bandwidth
  • 4K at 144 Hz refresh rate for smooth gaming visuals
  • 2K at 240 Hz refresh rate for competitive frame rates
  • HDR10 support expands colour depth and contrast range
  • Backwards compatible with DisplayPort 1.0 through 2.0 versions

Signal performance at length

The cable carries DisplayPort 2.1 traffic at 40 Gbps across a 10 ft run. It delivers 8K at 60 Hz, 4K at 120 Hz and 144 Hz, and 2K at 165 Hz and 240 Hz. HDR10 and 32 audio channels are supported. Backwards compatibility covers every DisplayPort version from 1.0 to 2.0.

Desktop users with high-refresh panels

Builders driving 4K 144 Hz or 2K 240 Hz monitors from modern graphics cards get the headroom they need. The tinned-copper conductors and FEC keep the link stable at this length. Buyers who only run 1080p 60 Hz displays will not use the extra bandwidth.

Bandwidth ceiling

The 40 Gbps rating is the single figure that decides whether the cable matches the monitor and GPU. If the display requires more than 40 Gbps — for example uncompressed 8K above 60 Hz — this cable cannot satisfy it.

Questions about this item

Does the 40 Gbps bandwidth of this DisplayPort 2.1 cable generate noticeable heat during all-day 8K@60Hz use?

The cable uses tinned copper conductors and carries 40 Gbps passively; it does not contain active electronics, so it runs at room temperature during continuous operation.

What must my graphics card and monitor already provide for this cable to deliver 4K@144Hz HDR10?

Both ends need a DisplayPort connector that supports DSC 1.2a and HBR10 signalling; the cable is backwards compatible with DP 2.0, 1.4, 1.3, 1.2, 1.1 and 1.0 but the source and sink must negotiate the required link rate.

Will this cable work with my older DP 1.2 monitor at 2K@165Hz while I upgrade the GPU later?

Yes — the cable is backwards compatible down to DisplayPort 1.0, so it will carry 2K@165Hz on a DP 1.2 display today and support 4K@144Hz or 8K@60Hz when you connect a newer GPU.
