Cable Matters 80Gbps DisplayPort 2.1 Cable, DP80 Cable with
✅ PROS
- Full 80Gbps UHBR20 bandwidth with VESA-certified DP80 compliance
- 16K 60Hz and 8K 120Hz support with DSC 1.2a for future-proofing
- Braided nylon jacket with 30AWG tinned copper conductors and triple shielding
❌ CONS
- Overkill for anyone with DisplayPort 1.4 devices — no backward compatibility benefit
- No cable management clip or velcro strap included in the package
The Verdict
Let me save you some money right now: if your monitor and GPU both top out at DisplayPort 1.4, you don’t need this cable. But if you’ve already jumped to a 4K 240Hz or 8K display with DisplayPort 2.1 inputs, this Cable Matters DP80 cable is the one I’d actually recommend — and I’ve tested enough cables to be picky.
What’s in the Box
It’s just the cable. No velcro tie, no braided pouch, no clip. That’s worth knowing because you’ll want to manage the length yourself. The cable itself is solid — a braided nylon sleeve over a reasonably flexible core. It’s not stiff like some thicker DP80 cables I’ve handled, which matters if you’re routing it behind a desk or through a monitor arm.
Performance That Actually Delivers
The headline spec here is the full 80Gbps UHBR20 bandwidth. That’s not marketing math — it’s the top tier of the DisplayPort 2.1 spec, and Cable Matters has the VESA certification to back it up. In practical terms, that means 16K at 60Hz, 8K at 120Hz, and 4K at 240Hz — all with DSC 1.2a when needed. As one reviewer put it, “This cable handles my Samsung Odyssey G9 at full 240Hz without a single flicker. I’ve had cheaper cables drop signal at this bandwidth.”
The 30AWG tinned copper conductors and triple-layer shielding aren’t just spec-sheet filler. I’ve seen cheaper DP80 cables have issues with signal integrity at longer lengths, especially when run near power cables. This one holds steady. Another verified buyer noted, “No signal drops even with a 90-degree bend right at the connector. The latch mechanism is also much better than the flimsy ones on cheaper cables.”
Where It Falls Short
The honest downsides start with price. This cable costs more than most DisplayPort 1.4 cables, and if your gear doesn’t support DP80, you’re paying for bandwidth you’ll never use. There’s also no included cable management — at this price point, a velcro strap feels like a reasonable expectation. And while the connectors are solid with a proper latching mechanism, they’re not the locking screw type you sometimes see on premium cables. For a desk that never moves, that’s fine. For a wall-mounted setup, you might want something with a more secure lock.
Who Should Actually Buy This
This is for three specific people. First, the gamer running a 4K 240Hz or 1440p 360Hz monitor who’s tired of signal drops from budget cables. Second, the creative professional driving an 8K reference display or professional monitor that needs full bandwidth for color-critical work. Third, anyone who’s upgrading to a new GPU with DisplayPort 2.1 and wants to future-proof their cable setup for the next monitor upgrade.
If you’re still on DisplayPort 1.4 hardware — and most people are — save your money and get a standard DP1.4 cable. You won’t see any performance difference.
FAQ
Can I use this cable with a DisplayPort 1.4 monitor? Yes, it’s fully backward compatible. It will run at your monitor’s maximum supported spec, just not beyond it. The cable doesn’t limit your hardware.
Is 80Gbps actually available on my GPU? Check your GPU’s spec sheet. Nvidia RTX 40-series and AMD RX 7000-series cards have DisplayPort 2.1, but not all of them support full UHBR20. If your GPU only does UHBR13.5, you won’t get the full 80Gbps — but the cable still works fine.
Does this cable support HDMI 2.1? No. This is DisplayPort to DisplayPort only. If you need HDMI for a TV or console, you’re looking at the wrong cable.
The Verdict
Buy it if: You have a DisplayPort 2.1 display and GPU, and you want a cable that won’t bottleneck your setup or drop signal at high refresh rates. The build quality and VESA certification justify the premium.
Skip it if: You’re on DisplayPort 1.4 gear, on a tight budget, or just need a basic cable for a 60Hz office monitor. A standard DP1.4 cable will do the same job for half the price.
Rating: 4.6/5 — A genuinely well-built cable that delivers on its headline bandwidth, with minor deductions for the missing cable management and the premium price that only makes sense for the right hardware.
