Product information

Description

Connect an 8K or 4K UHD DisplayPort monitor to a host computer or MST hub with this VESA-Certified DisplayPort 2.1 DP40 cable. It enables high-bandwidth video and multi-channel audio for 8K workstations, high-performance GPUs, and AV applications such as media production and content creation.

Advantages

The DisplayPort 2.1 DP40 cable is VESA Certified for DP 2.1 and backward compatible with DP 2.0/1.4/1.2. It supports Variable Refresh Rate technologies including G-Sync and FreeSync, improving synchronization between supported GPUs and displays. The cable’s TPE outer jacket is designed for flexibility and is tested for 600 bending cycles at ±60 degrees. Latching nickel-plated connectors provide secure attachment and are rated for more than 10,000 insertions. Braided aluminum mylar shielding reduces EMI for stable audio/video transmission.

Key specifications

Standard: DisplayPort 2.1 (VESA Certified)
Max resolution: Up to 8K 60Hz with DSC (using compatible DP source and display)
UHBR support: UHBR10 enabling 4K 120Hz and 1440p 240Hz
Compression: Display Stream Compression (DSC) 1.2a
HDR: HDR10 support
Content protection: HDCP 2.2
Audio: Up to 32 uncompressed digital audio channels
MST: Multi-Stream Transport for daisy-chaining monitors
Backward compatibility: DP 2.0 / 1.4 / 1.2
Connector durability: Rated beyond 10,000 insertions
Cable jacket: Flexible TPE, tested for 600 bending cycles at ±60°
Shielding: Braided aluminum mylar to minimize EMI

How to use

Plug the latching DisplayPort connector into the DP output of your host computer, GPU, or MST hub and attach the other end to the DisplayPort input on your monitor. Ensure both source and display support DP 2.1 features such as UHBR10 and DSC if you require 8K 60Hz or high refresh rate modes. Secure the latches to prevent accidental disconnection and route the cable using its flexible TPE jacket to avoid sharp bends. For multi-monitor setups, enable MST on the host or hub and chain displays according to the monitor and GPU instructions.

Recommendations

Use with DP 2.1-enabled hosts and displays for full 8K/60Hz and UHBR10 performance; verify source and display compatibility for DSC, HDR10 and HDCP 2.2. Keep cable bends gentle and avoid pinching to preserve shielding and connector life.
