What this cable delivers

This SMUGDESK DisplayPort 2.1 cable carries 80Gbps bandwidth and supports 16K at 30Hz with DSC, plus 8K at 120Hz and 4K at 240Hz. It is VESA certified and backwards compatible with DisplayPort 1.4, 1.3 and 1.2. The 3.3FT length suits typical desk setups between a GPU and a monitor.

Who benefits and who does not

Gamers driving 1440p at 360Hz or 4K at 240Hz get the headroom they need for variable-refresh panels using FreeSync or G-Sync. Buyers whose graphics card or display only offers HDMI or an older DisplayPort revision will not gain the advertised 80Gbps link speed. The cable does not add HDR or DSC support to hardware that lacks it.

Build integration notes

Connect the DP 2.1 plugs directly to a compatible GPU such as an RTX 3080 or RTX 3090 and a high-refresh gaming monitor. No external power or driver install is required. The slim 3.3FT run keeps cable routing simple inside compact cases while leaving enough slack for monitor adjustment.

Questions about this item

What graphics card or source device do I need to reach 4K@240Hz over this DisplayPort 2.1 cable?

You need a GPU or source with a DisplayPort 2.1 output that supports UHBR20 (80 Gbit/s) and DSC 1.2a, such as an RTX 30-series or newer card, plus a monitor that accepts 4K@240Hz over DP 2.1.

Will this cable work with my older RTX 2070 and a 1440p@144Hz monitor?

Yes. The cable is backwards compatible with DP 1.4, 1.3 and 1.2, so an RTX 2070 driving 1440p@144Hz will work without issue.

How can I verify the link is running at the full 80 Gbit/s after I connect everything?

Open your GPU control panel or monitor OSD and confirm the link shows UHBR20 or 80 Gbit/s, the target resolution and refresh rate (for example 4K@240Hz), and that DSC is active.
