What this cable is

The LUOM LJ-DP16K is a 3.3 ft DisplayPort 2.1 cable rated for 40 Gbps bandwidth. It carries 8K at 60 Hz, 4K at 144 Hz and 2K at 240 Hz using HBR10 signalling. Triple shielding and 28 AWG oxygen-free copper conductors keep the signal stable. The cable is VESA certified and backwards compatible with DisplayPort 2.0, 1.4 and earlier versions.

Who should buy it and who should not

Gamers and creators driving 8K 60 Hz or 4K 144 Hz monitors from a DisplayPort 2.1 source will get the full refresh rate. Users needing runs longer than 3.3 ft must choose a different length because this cable is fixed at that distance. Buyers whose displays only have HDMI inputs cannot use this cable without an active adapter. Multi-stream transport and DSC are supported for daisy-chained setups.

The spec that decides fit

Bandwidth is capped at 40 Gbps with HBR10 certification, so any display mode requiring more throughput will not work. The male-to-male DisplayPort 2.1 connectors fit standard DP ports on desktops, laptops and projectors listed in the compatibility data. FEC forward error correction and 32 audio channels are included. If your hardware tops out at 4K 60 Hz, this cable still works but provides headroom you will not use.

Questions about this item

What does the 40 Gbit/s bandwidth actually deliver when the cable is plugged into a real system?

The 40 Gbit/s rating enables 8K at 60 Hz, 4K at 144 Hz or 120 Hz, and 2K at up to 240 Hz, provided both the source and display support those modes.

Which DisplayPort standard does the cable implement and what practical limit does that impose?

It implements DisplayPort 2.1 with HBR10 signalling, capping the link at 40 Gbit/s and allowing 8K 60 Hz or 4K 144 Hz without compression.

What physical connectors does the cable use and how much space do they need behind the port?

Both ends are standard male DisplayPort plugs with thumb latches; allow enough rear clearance for the latch to release cleanly.
