Cable purpose and audience

The LUOM TJ-A285BK is a DisplayPort 2.1 cable built for gamers and creators who need 80 Gbps bandwidth over a 6.6 ft link. It carries 16K at 30 Hz with DSC, 8K at 120 Hz, and 4K at up to 240 Hz, making it suitable for high-refresh gaming monitors and professional displays.

Who it suits and who it does not

Buyers running DisplayPort 2.1 or earlier sources with matching sinks will get the full feature set including HDR, HDCP 2.2 and MST. Systems limited to HDMI-only outputs or older GPUs without DisplayPort connectors cannot use this cable, and installations needing longer runs should consider active or optical alternatives.

Behaviour under sustained load

Triple shielding and solid copper conductors keep signal integrity stable during extended sessions at 4K 240 Hz or 8K 120 Hz. The aluminium shell dissipates heat and the 15,000-bend rating means repeated handling or tight routing will not degrade performance over time.

Questions about this item

What DisplayPort version must my graphics card and monitor support to use this cable at its full 80 Gbps bandwidth?

Both devices need DisplayPort 2.1 ports to reach the cable's rated 80 Gbps speed and enable resolutions like 16K at 30 Hz or 4K at 240 Hz.

Will this DisplayPort 2.1 cable work with my older GTX 1080 or RTX 2080 graphics card and a DisplayPort 1.4 monitor?

Yes, the cable is backwards compatible with DisplayPort 1.3, 1.2, 1.1a and 1.0, so it will function with a GTX 1080 or RTX 2080 at the maximum resolution and refresh rate those devices allow.

How can I verify the cable is delivering 4K at 165 Hz or 8K at 120 Hz after I connect it?

Open your GPU control panel or Windows display settings and confirm the selected resolution shows 3840×2160 at 165 Hz or 7680×4320 at 120 Hz with HDR enabled; the monitor's on-screen menu should report the same figures.
