LUOM TJ-A022 DisplayPort cable 66 ft 1.4 32.4Gbps 8K 60Hz 4K 144Hz

What this cable is for

This LUOM DisplayPort 1.4 cable links a graphics card or laptop to a monitor, projector or HDTV over a distance of 66 ft. The hybrid glass-fibre and copper construction keeps the signal stable where a standard copper cable would degrade. It is aimed at PC builders and AV installers who need long-run 8K or high-refresh 4K connectivity. It will not suit buyers who need a short desk-length cable or who want to run multiple displays from a single output.

The spec that decides fit

The cable is certified for DisplayPort 1.4 and delivers up to 32.4 Gbps total bandwidth, which corresponds to HBR3 at 8.1 Gbps per lane. That throughput supports 8K at 60 Hz, 4K at 144 Hz and 2K at 240 Hz, with backward compatibility down to 1080p. If your source or sink only implements DisplayPort 1.2, the link will still work but at the lower 1.2 speeds. It will not work for buyers whose equipment requires DisplayPort 2.0 or UHBR bandwidth.

Thermals noise and power

As a passive optical cable it draws no external power and produces no fan noise. The fibre cores generate no measurable heat during normal video transmission, so the jacket remains at ambient temperature. The 24K gold-plated connectors resist corrosion and maintain low contact resistance over repeated mating cycles. It will not suit installers who need an active copper cable with built-in signal conditioning for runs beyond the rated length.
