DisplayPort extension designed to preserve high resolutions and refresh rates for short monitor set-ups, the Duttek DisplayPort Cable 2.1 promises reliable, high-bandwidth connections. Tidy cable runs and uninterrupted gameplay reduce setup stress for desk-focused users. Is the short angled extension the right fit for compact gaming rigs and multi-monitor workstations?

⚡ At a Glance
  • Bandwidth: UHBR3 40 Gbps supporting high resolutions and refresh rates
  • Best for: Gamers and multi-monitor professionals needing short, angled extensions
  • Not ideal for: Set-ups requiring long cable runs beyond a short extension

Compact 15cm right-angle DisplayPort 2.1 extension capable of high-resolution connections. Nylon braid and 24K gold-plated connectors help maintain signal integrity and connector longevity.


Smooth high-refresh gaming, with UHBR3 40 Gbps bandwidth

UHBR3 signalling raises maximum throughput to 40 Gbps, enabling 16K at 30 Hz and 8K at 120 Hz where displays and GPUs allow. Backward compatibility with DP 1.4 and earlier lets older kit run at supported rates.

Stable, high-resolution picture and high frame-rate support for modern GPUs and gaming monitors. Frame pacing remains consistent when matched with compatible hardware.

Space-saving monitor positioning, with a 90-degree short male-to-female extension

The short 6-inch, right-angle male-to-female form keeps the connector close to the monitor port and redirects the cable away from the screen edge. The design avoids bulky straight plugs that can push monitors away from walls.

Allows monitors to sit flush against a desk or wall and eases cable routing in cramped desks. Ideal for corner workstations and VESA-mounted displays.

Reliable, interference-resistant signal, with triple shielding and tinned conductors

Triple shielding combined with 28 AWG tinned copper conductors and tinplate blocks reduces electromagnetic interference and signal loss. 24K gold-plated connectors improve conductivity and resist corrosion over many insertions.

Consistent image quality during high-bandwidth transfers and less susceptibility to nearby electrical noise. Connectors withstand frequent swapping thanks to tested insertion durability.
