USB-C to DisplayPort 1.4 Cable

The LUOM TJ-A055 cable connects a USB-C source with DisplayPort Alt Mode to a DisplayPort 1.4 monitor. It suits creators and gamers who need 8K 60 Hz, 4K 144 Hz or 2K 240 Hz video on a single 6.6 ft link. Thunderbolt 3 and 4 hosts are also supported.

Passive Cable Thermals and Power

The triple-shielded 28 AWG tinned copper construction carries 32.4 Gbps without active electronics, so the cable itself generates no heat and draws no external power. The built-in CYPD smart chip handles link training and DSC 1.2 compression for a stable, flicker-free signal.

Plug-and-Play Accessory Bundle

No driver or software installation is required; the male-to-male connectors enable instant mirror or extend modes, including MacBook clamshell operation when the laptop is powered. The unidirectional design does not carry charging current, so a separate power cable remains necessary for the host device.

Questions about this item

How do I install the LUOM TJ-A055 cable and which end plugs into the source?

Plug the USB-C connector into the Thunderbolt 3 or 4 port on your laptop, tablet or phone that supports DP Alt Mode, then connect the DisplayPort 1.4 end to the monitor. The cable is unidirectional so the USB-C side must face the source device.

What maintenance or replacement will the LUOM TJ-A055 cable need over time?

The triple-shielded 28 AWG tinned copper conductors and solid copper core are built for long-term use; no scheduled maintenance is required. Replace the cable only if the connectors become loose, the jacket is damaged or signal drop-outs appear.

At what point does the LUOM TJ-A055 cable hit its bandwidth ceiling during sustained 8K 60 Hz HDR output?

The DisplayPort 1.4 link tops out at 32.4 Gbps, so 8K at 60 Hz with 10-bit HDR uses the full HBR3 pipe. Pushing higher refresh rates at 8K would exceed the cable’s certified bandwidth limit.
