JSAUX 8K DisplayPort 1.4 Cable (DP to DP) 2m – 240Hz support for gaming and high-resolution displays
Product description
What it is and what problem it solves
This JSAUX 8K DisplayPort 1.4 cable is a DP-to-DP lead designed to carry video (including high refresh rates) between a DisplayPort source and a DisplayPort screen. In practice, it’s aimed at people who want a single cable solution for gaming monitors as well as higher-resolution viewing on PCs and some TVs with the right input.
The headline idea is clear: DisplayPort 1.4 and the stated bandwidth figures are meant to give you headroom for resolutions like 4K and 2K at higher frame rates, while still supporting higher-end modes up to 8K@60Hz. It’s not perfect for every setup, though—if your device only has HDMI, you’ll be stuck because this is explicitly DP to DP.
For a quick real-world example: if you’ve got a gaming laptop/PC with a DisplayPort output and a monitor that supports high refresh rates, replacing a basic cable with a DP 1.4 model can help you actually run the monitor at the settings you paid for, rather than settling for something lower “just to make it work”.
The essentials (so you can judge fit quickly)
If your goal is smooth motion on a DisplayPort gaming monitor, this cable is positioned for 240Hz-class performance and “clean” signal handling—specifically it’s marketed around avoiding motion blur, screen tearing and flickering when you’re pushing high frame rates.
On the spec side, the cable is described as supporting: - A 32.4Gbps bandwidth claim with DisplayPort 1.4 - High resolution modes including 8K@60Hz, 5K@60Hz, 4K@144Hz and 2K@240Hz (plus 1080P@240Hz) - Dynamic HDR support and HDCP 2.2
There’s also support mentioned for FreeSync and G-Sync, which is relevant if you use variable refresh rate features on your display. Not everyone needs those, but if you do, it’s reassuring when the cable supports the ecosystem you’re already using.
Worth noting: marketing refresh-rate claims are only half the story—your GPU and monitor both need to support the same modes. The cable can enable the capability, but it can’t create compatibility where none exists.
Where it stands out in everyday use
A DisplayPort 1.4 cable like this tends to be most noticeable in two scenarios: when you’re gaming at higher refresh rates and when you’re running higher-resolution content without wanting to think about signal drop-out.
It’s also set up with durability in mind. The connectors are described as 24K gold plated, and the cable uses a nylon braided build. That combination usually matters for day-to-day handling—things like repeated plugging/unplugging, tight cable routing behind a desk, and general long-term wear.
If you’re wiring a PC to a monitor on a monitor arm or you route behind a desk, a braided cable often feels more “sturdy” than cheaper unbraided leads, even if it won’t magically make every setup easier.
What to watch before you buy
There are a few practical checks that can save you hassle:
First, confirm the ports on both ends. This is a DisplayPort to DisplayPort cable, and the listing specifically says it is not compatible for HDMI ports. If your monitor or laptop only has HDMI, you’ll need a different approach.
Second, double-check your target mode. The cable is described as supporting impressive combinations (like 4K@144Hz and 2K@240Hz), but whether you get that depends on your graphics card and the monitor’s supported timings. It may not suit you if your main goal is, say, console-to-TV setups that need HDMI.
Finally, don’t ignore length. At 2m, it’s a sensible desktop distance for many setups, but if your desk is very close—or you’re mounting the screen with a long run—2m might be either too short or just a little awkward.

Should you buy it?
A solid pick if you’ve got a DisplayPort-enabled laptop/PC and a gaming monitor (or high-resolution DisplayPort screen) and you want to run higher refresh rates and resolution modes without constantly worrying about signal quality. It also makes sense if you care about features like Dynamic HDR and HDCP 2.2 on compatible content.
It might not be a great match if your setup needs HDMI, because this is DP to DP only. You may also want to skip it if your displays are older/limited and you’re not actually going to use the higher refresh-rate or resolution combinations it supports—then you’re paying for headroom you won’t benefit from.
Mini FAQ
FAQs
Is this cable HDMI compatible? No. It’s described as DisplayPort to DisplayPort and not compatible with HDMI ports.
Can it really do 240Hz? The listing says it supports 240Hz modes (including 2K@240Hz and 1080P@240Hz). Just keep in mind your PC/GPU and the monitor also need to support the same settings.
Will it work with FreeSync and G-Sync? The product description states support for both FreeSync and G-Sync.
Does it support high-resolution modes like 8K? It’s advertised as supporting 8K@60Hz, along with other listed resolutions such as 4K@144Hz and 2K@240Hz.
What length do I get? You get a 2m red cable, according to the listing.
