What this cable connects

The Jansicotek LJ-DP16K is a VESA Certified DisplayPort 2.1 cable, 3.3 ft long, rated for 40 Gbit/s bandwidth. It carries video and audio between a DisplayPort 2.1 source and a DisplayPort 2.1 display using male-to-male connectors. The cable supports HBR10, HBR3, HDCP 2.2, HDCP 1.4, HDR, DPCP 1.0, stereoscopic 3D, Multi-Stream Transport and DSC compression.

Who this suits and who should look elsewhere

Builders connecting an RTX 3080 or RTX 3090 graphics card to a monitor that accepts DisplayPort 2.1 input will get the full 8K 60 Hz or 4K 144 Hz capability. Gamers targeting 2K 240 Hz or 165 Hz refresh rates also benefit. Buyers whose source or display only provides DisplayPort 1.2 or 1.4 ports cannot use the higher link rates this cable enables. Anyone needing a longer run than 3.3 ft must choose a different length.

The spec that decides fit

The cable is rated for 40 Gbit/s (HBR10) bandwidth. If both your graphics card and your monitor implement DisplayPort 2.1 with UHBR10 or UHBR13.5 links, this cable will deliver 8K at 60 Hz, 4K at 144 Hz, or 2K at 240 Hz without compression artifacts. If either end tops out at a lower link rate, the extra headroom goes unused.

Questions about this item

Does the 3.3 ft DisplayPort 2.1 cable generate noticeable heat or draw extra power during all-day 8K 60 Hz use?

The cable is passive with solid copper conductors and triple shielding, so it adds no active heat or power draw; signal integrity at 40 Gbit/s is maintained without external power.

Must my graphics card and monitor both have native DisplayPort 2.1 ports for this male-to-male cable to work?

Yes, both source and display need a DisplayPort 2.1 connector to unlock the full 40 Gbit/s bandwidth and 8K 60 Hz or 4K 144 Hz modes.

Will this cable function correctly if I keep an older DisplayPort 1.2 monitor on the same GPU?

The cable is backward compatible with DisplayPort 1.2, 1.4 and earlier versions, so an older monitor will operate at its maximum supported resolution and refresh rate.
