Product description
What this DisplayPort 2.1 cable is for
JSAUX’s DisplayPort 2.1 cable is aimed at people who want headroom for modern monitor specs—especially if you’re building a gaming setup with higher refresh rates and sharper resolution targets. On paper, it supports up to 16K@60Hz, 8K@120Hz, and 4K at very high refresh rates (listed as up to 240Hz, with several other modes also mentioned). It’s also positioned as backward compatible with DP 1.4 and DP 1.2, which matters if your monitor or GPU isn’t fully “DP 2.1-ready.”
If you’re shopping because you’ve seen screen tearing, stutter, or you just want smoother motion for fast games, this cable tries to cover that use case with features tied to smoother playback (it mentions VRR and ALLM). That’s the practical pitch: fewer “it can’t do that” moments when you’re trying to match your display’s settings.
Key points (what stands out)
The headline here is bandwidth. The cable is described as supporting an 80 Gbps bandwidth, and it also references DSC 1.2a, HDCP 2.2, HDR, and audio support. In normal buyer terms, that means it’s designed to carry demanding display signals—without you having to think too hard about whether your cable is the bottleneck.
Another detail worth noting is how the package is framed for gaming: it calls out up to 240Hz refresh support (but you should still confirm your monitor supports 240Hz if that’s your goal). There’s also a note that the cable can be relatively rigid, which can be fine in a fixed desk setup, but less ideal if you need a very flexible cable route.
Where the appeal really lands is for people who want one DisplayPort cable that’s meant to handle high-end resolutions and high refresh targets today, and not feel immediately outdated.

Everyday use: what it feels like in a gaming/monitor setup
Picture setting up a gaming monitor and wanting to run high refresh at a native-looking resolution. With this cable, the intent is that you can actually reach those targets through DisplayPort—so you can go into your monitor settings and pick the higher refresh options without the cable being the weak link.
For fast gameplay (FPS, 3A, MOBA—those are the categories mentioned), the cable is described as supporting smooth motion and reducing the kinds of issues people typically associate with tearing or stutter, especially when VRR is available. Real-world results depend on your GPU, monitor, and the settings you choose, but the spec goals are clearly aligned with that kind of use.
Who it’s for—and who should skip it
Worth considering if you want a longer (13FT) DisplayPort cable that’s built for higher-end DisplayPort 2.1 capabilities, and you’re the type who actually uses your monitor’s advanced refresh/resolution settings.
It may not be a great match if you only have a basic office monitor or your system can’t realistically use those refresh/resolution modes—because in that case, you might be paying for features you won’t be able to take advantage of.
Also, keep in mind the cable is described as “relatively rigid.” If your setup needs lots of flexibility (frequent movement, tight bends, or a mobile desk), that stiffness could be annoying.
What to double-check before you buy
This cable can support strong performance targets, but you’ll still want to confirm a few things so it doesn’t end up being “technically capable, practically wasted.”
- Your monitor’s supported refresh rate and resolution over DisplayPort (especially if you want the top refresh modes).
- Whether your laptop/graphics card supports the same DisplayPort version/features you’re trying to use.
- Your routing needs, since it’s described as relatively stiff.
If any of those don’t line up, the cable may not deliver the best experience you’re expecting—even though it’s designed for it.
In the box
You get a gray JSAUX DisplayPort 2.1/2.0 cable, 13 feet long. If you run into issues, the listing mentions contacting JSAUX for help.
Is it worth it?
Buy it if you’re building or upgrading a DisplayPort gaming/monitor setup and you want a DP 2.1 cable that’s designed to handle high refresh and high resolution targets (including support claims for VRR/ALLM and compatibility with DP 1.4/1.2). It’s the kind of “future-reserve” cable that makes sense when you don’t want to think about signal limits.
Skip it if you don’t plan to use higher refresh modes or your display/GPU setup won’t realistically take advantage of the resolution/Hz targets listed. And if you need a highly flexible cable for constant repositioning, the mentioned rigidity may be a dealbreaker.
Quick FAQ
Will this work with DP 1.4 or older DisplayPort setups?
The listing says it’s backward compatible with DP 1.4 and DP 1.2, so it should work with older DisplayPort configurations, though your achievable resolution/refresh will depend on the devices.
Do I need a monitor that supports 240Hz?
If you’re trying to use the top refresh modes mentioned (like 240Hz for 4K), you should confirm your monitor actually supports that over DisplayPort.
Does it support HDR and audio?
Yes—HDR (dynamic HDR mentioned) and audio support are included in the listed capabilities.
Is the 13FT length a problem for signal performance?
The cable is specifically sold as 13FT and is described with high bandwidth support. Still, your end result depends on your monitor and GPU, so it’s smart to verify your intended settings will be supported.
