LUOM DisplayPort 2.1 Cable

The LUOM LJ-DP16K is a VESA certified DisplayPort 2.1 cable designed for users who need 40 Gbps bandwidth between a graphics card and a monitor. It carries 8K at 60 Hz or 4K at 144 Hz with HDR and HDCP 2.2 support. The 3.3 ft male-to-male link suits desktop PCs, laptops and gaming displays that have native DisplayPort inputs.

Ultra-slim build for tight routing

A 28 AWG oxygen-free copper conductor and triple shielding keep the cable thin enough to thread behind cramped desk setups or through narrow grommets without pressing on adjacent ports. Backward compatibility with DisplayPort 2.0 and 1.4 lets it serve older GPUs such as a GTX 980 or Radeon R9 290 while leaving headroom for newer hardware. No external power or extension cord is required.

40 Gbps headroom and resolution limits

The HBR10-rated link handles 7680 x 4320 at 60 Hz, 5120 x 2880 at 60 Hz, 4096 x 2160 at 144 Hz and 2560 x 1440 at 240 Hz with DSC enabled. It also supports 1920 x 1080 at 360 Hz for competitive gaming and 7.1 uncompressed audio pass-through. Bandwidth runs out at 16K 30 Hz single-stream or dual 8K 120 Hz, so buyers needing higher refresh at 8K or multi-monitor 8K 144 Hz should look elsewhere.

Questions about this item

Will the 40 Gbit/s bandwidth limit the 8K 60 Hz signal over the 3.3 ft run?

The cable is rated for HBR10 at 40 Gbit/s, which matches the 8K 60 Hz specification, so the bandwidth ceiling is not reached under normal use.

Does the triple-shielded 28 AWG copper construction stay cool and quiet during all-day 4K 144 Hz gaming?

Passive copper cables generate no fan noise and negligible heat; the triple shielding and solid conductors keep signal integrity stable during extended sessions.

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

The cable plugs into any DisplayPort socket; it is backward compatible with DP 2.0 and DP 1.4, so older GPUs like GTX 980 or Radeon R9 290 will function at their maximum supported rates.
