LUOM LJ-DP16K DisplayPort 2.1 cable 6.6 ft 40 Gbit/s 8K 60 Hz 4K 144 Hz

What the cable is and who it is for

The LUOM LJ-DP16K is a DisplayPort 2.1 cable rated at 40 Gbit/s and built with triple-shielded oxygen-free copper conductors. It connects a DisplayPort 2.1 source to a DisplayPort 2.1 display over a 6.6 ft male-to-male link. The cable is VESA certified and carries HBR10 bandwidth with forward error correction for stable signal integrity.

Who this suits and who should look elsewhere

Gamers and creators driving 8K at 60 Hz, 4K at 144 Hz or 2K at 240 Hz will use the full HBR10 pipe without compression artefacts. Buyers needing runs longer than 6.6 ft, or those whose monitors only offer HDMI inputs, cannot use this cable as-is and should consider active optical or HDMI alternatives.

Capacity and headroom

The link handles 8K 7680 x 4320 at 60 Hz, 4K 4096 x 2160 at 144 Hz and 2K 2560 x 1440 at 240 Hz with DSC where noted. It also passes uncompressed 7.1 or 5.1 audio and supports HDR 10 plus HDCP 2.2. At 16K 30 Hz the bandwidth ceiling is reached, so higher resolutions or multi-head 8K 120 Hz setups exceed the 40 Gbit/s limit.
