3.3 ft DisplayPort 2.1 cable for high-refresh gaming

The LUOM TJ-A285BK is a male-to-male DisplayPort 2.1 cable measuring 3.3 ft. It supports up to 80 Gbps bandwidth and carries resolutions up to 16K at 30 Hz with DSC. The cable is aimed at PC builders connecting modern graphics cards to high-refresh gaming monitors or televisions.

Triple-shielded copper construction fits tight

The 3.3 ft length suits same-desk connections between a GPU and a monitor without excess slack. Triple shielding and solid copper conductors protect signal integrity at 80 Gbps. Backwards compatibility with DisplayPort 1.4, 1.3 and 1.2 lets the cable work with older ports while still delivering full 2.1 performance on new hardware.

Sustained 80 Gbps throughput for long sessions

The cable maintains the full 80 Gbps link rate during extended gaming or video playback, supporting 4K at 240 Hz, 1440p at 360 Hz and 8K at 120 Hz without dropouts. HDR10, HDCP 2.2 and DSC 1.2a stay active continuously. Buyers needing longer runs for projector installs or multi-monitor walls will need a different length.

Questions about this item

Does the 80 Gbps bandwidth of this DisplayPort 2.1 cable sustain 4K at 240 Hz over the full 3.3 ft length?

The cable is rated for 80 Gbps and supports 4K at 240 Hz with DSC 1.2a, so the bandwidth headroom is there for the 3.3 ft run.

Will the triple-shielded solid-copper construction stay cool and quiet during all-day 4K 240 Hz gaming?

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

Must my graphics card and monitor both have DisplayPort 2.1 ports to use this cable?

The cable is backwards compatible with DisplayPort 1.4, 1.3 and 1.2, so it works with older ports but only reaches 4K 240 Hz on DP 2.1 hardware.
