Cable Matters [VESA Certified] 80Gbps DisplayPort 2.1 Cable 1.5m, DP80 Cable with 16K 60Hz, 8K 240Hz, 4K 240Hz in Black with FreeSync, G-SYNC and HDR for Gaming Monitor, PC, RTX 4080/4090, RX 7900

I can confirm that this does work just fine at 1440p 240hz as this is what my Samsung monitor runs at.Its quite a chunky cable however this is to be expected, but it can make routing a little challenging.Offers fair value as it does what it says just fine.

The Cable Matters 80Gbps DisplayPort 2.1 cable promises high-bandwidth performance for the latest generation of gaming monitors and graphics cards, and for the most part, it delivers. This 1.5-meter cable boasts support for impressive resolutions and refresh rates, including 16K@60Hz, 8K@240Hz, and 4K@240Hz. This makes it ideal for users with high-end setups.The cable feels robust and well-built. The connectors are securely fastened and show no signs of weakness, suggesting good longevity. FreeSync, G-SYNC, and HDR are all supported, ensuring a smooth and visually stunning gaming experience.

I have had other cables from Cable Matters in the past and all of them were great quality. This cable doesn't disappoint either, it's really well made, solid yet flexible and sits really well connected in the DP sockets.Performance-wise there's not much to say, it works exactly as expected, I tested it playing a game with HDR enabled and a 160Hz refresh rate @4K resolution and all worked perfectly.Great cable at a good price and will be buying form this brand again in the future.

Seems like a good solid cable, works well enough.Has locking clips at either end.

No issues with this. Performs to spec with all variations of resolutions, refresh rates, HDR, colour depths, etc.It's a safe bet in terms of compatibility whatever your setup is like.The build quality of the cable itself is decent. It will last forever if you treat it right. The huge release latch buttons are excellent. The lip and side grips at the end of the connections are surprisingly great at making removing them easier. Simple solutions to some not very serious issues.

Used this to replace a 'high quality' displayport 1.4 spec cable, had odd intermittent flickering with vrr enabled prior, since using this cable it seems to of solved it!Feels well made, has nice press to release connectors, Signal quality at least at 1440p @ 180hz with HDR and VRR seems stable!Happy with this for it's use case, prefer to buy over slecced cables now as it does seem to be more of an issue as bandwidth requirements keep increasing!Yes this cable costs a bit more but it's well made, I personally feel at just under £15 for the 1.5m length is worth it to stop annoying issues that distract from a good monitor!

I got this cable a while ago for both extension and speed matching with a 4090 and MSI 321urx monitor. It was working great at first, but after about 2 weeks, it started flickering over my screen, not only while playing a game, but also when watching a movie or just navigating through windows. So I thought the problem might be coming from my devices but it wasn't, since I switched between 2 DP ports and ran every test, I decided to change back to the cable inside my monitor's box. It's working fine with the factory cable and I think Cable Matters won't be worth the hassles.

Not much to say about this one - this is a basic yet quality Cable Matters cable that i'm currently using with an RTX 4090 and a 32" 4K monitor at 240hz.This cable supports this specification and works well, with no issues in it's use at full resolution and frame rate.It clips in reliably to the ports and holds fast, preventing unwanted slips.Excellent bit of kit.
