Jansicotek LJ-DP16K DisplayPort 2.1 Cable

This 3.3 ft DisplayPort 2.1 cable carries up to 40 Gbit/s bandwidth and supports 8K at 60 Hz, 4K at 144 Hz, and 2K at 240 Hz. It is built for gamers and creators who need high refresh rates at high resolutions. The male-to-male connectors work with DP, DP++, and DisplayPort++ ports on graphics cards and monitors.

Installation and Common Issues

The cable is plug-and-play with no drivers required. Its latch-free connectors seat securely but release easily when pulled straight out. The triple-shielded, nylon-braided jacket resists kinking and EMI, while 24k gold-plated terminals reduce oxidation. Do not use extension cords, as they can break the signal integrity needed for 40 Gbit/s throughput.

Who This Suits and Who Should Look Elsewhere

Ideal for users connecting a DisplayPort 2.1 GPU to an 8K or high-refresh 4K monitor within a short desk run. The 3.3 ft length fits typical monitor-to-PC distances. Buyers needing longer runs, in-wall routing, or angled connectors for tight spaces should look elsewhere.

Questions about this item

How do I verify the cable is running at 40 Gbit/s after connecting it?

Open your GPU control panel and confirm the link is negotiated at UHBR10 with DSC active; the panel should report 8K at 60 Hz or 4K at 144 Hz without compression artefacts.

What comes in the box and is anything else required?

The package contains the 3.3 ft DisplayPort 2.1 male-to-male cable only; no adapters or power supplies are included or needed for standard DP 2.1 ports.

Which length should I choose for a desktop-to-monitor run?

The 3.3 ft length suits typical desk distances; if the monitor sits farther away you would need a longer cable, but only this length is offered for this model.
