LUOM LJ-DP16K DisplayPort 2.1 Cable 6.6 ft 40 Gbit/s

Target Use

The LUOM LJ-DP16K is a DisplayPort 2.1 cable built for users who need 40 Gbit/s bandwidth between a graphics card and a high-refresh display. It suits 8K at 60 Hz, 4K at 144 Hz and 2K at 240 Hz workflows. Backward compatibility with DP 2.0 and DP 1.4 lets it serve older GPUs such as Radeon R9 290 or GTX 980. Buyers who require longer runs than 6.6 ft or fibre-optic isolation should look elsewhere.

Signal Integrity

Triple-layer shielding and 28 AWG oxygen-free copper conductors suppress electromagnetic interference during sustained high-bit-rate transmission. The copper construction keeps the cable slim and flexible for tight routing behind a desk. No active electronics or external power are involved, so the link adds no audible noise or measurable latency. The passive design means signal quality depends on the host and display PHY performance.

Physical Build

Male-to-male DisplayPort 2.1 connectors feature latching tabs for a secure fit on BenQ, Dell, HP, Acer, iiyama, Alienware and Odyssey monitors. The 6.6 ft length reaches most tower-to-monitor distances without excess slack. VESA certification confirms compliance with the DP 2.1 specification. Users needing right-angle plugs or locking screws beyond the standard latch will need a different cable.
