Jansicotek LJ-DP16K DisplayPort 2.1 Cable 6.6 ft

This DisplayPort 2.1 cable carries 40 Gbps bandwidth over a 6.6 ft male-to-male link. It is built for users who need certified 8K 60 Hz or 4K 144 Hz video from a graphics card to a monitor. Triple shielding and solid copper conductors protect signal integrity across the full length.

Suits 8K 60 Hz and high-refresh 4K setups.

The 6.6 ft reach fits typical desk distances between a GPU and a display. Buyers routing cables through walls, across rooms or between racks will need a longer or active solution. The fixed male connectors also prevent use with panel-mount or extension scenarios.

HBR10 40 Gbps bandwidth enables 8K 60 Hz with DSC

VESA HBR10 certification guarantees 40 Gbit/s throughput, the single spec that unlocks 7680 x 4320 at 60 Hz with Display Stream Compression 1.2a. Without this rated bandwidth the cable cannot deliver the advertised 8K or 4K 144 Hz modes.

Questions about this item

Should I pick the 6.6 ft length or a shorter DisplayPort 2.1 cable?

The 6.6 ft length gives full 40 Gbps bandwidth for 8K at 60 Hz or 4K at 144 Hz without signal loss. Shorter cables offer the same specs, so choose the length that fits your desk layout.

What does the 40 Gbps rating actually deliver on my monitor?

It enables 8K at 60 Hz with DSC, 4K at 144 Hz, and 2K at 240 Hz, plus HDR and 7.1 audio pass-through, provided your graphics card and display support those modes.

How does the DisplayPort 2.1 HBR10 interface limit real-world performance?

HBR10 caps the link at 40 Gbps, so 8K requires Display Stream Compression while 4K at 144 Hz and 2K at 240 Hz run uncompressed within that bandwidth ceiling.
