LUOM TJ-A009 DisplayPort 1.4 Switch

The LUOM TJ-A009 is a bi-directional DisplayPort 1.4 switch designed for users who need to share a single 8K monitor between two computers or send one computer signal to two displays. It suits home-office workers, content creators and gamers who want manual source selection without unplugging cables. The compact black unit requires external USB power to operate.

8K 60Hz and 4K 120Hz bandwidth

This switch passes DisplayPort 1.4 signals up to 32.4 Gbps, enabling 8K resolution at 60 Hz, 4K at 120 Hz, 1440p at 165 Hz and 1080p at 240 Hz. It supports 10-bit colour depth, HDR and 4:4:4 chroma subsampling for full-quality video. Simultaneous output to both displays is not possible; only one active path is available at a time.

Passive thermal design with external power

The aluminium enclosure dissipates heat without a fan, so the device runs silently in normal use. Power draw is limited to the included 5 V DC USB cable, which must be connected for any signal to pass through. No additional cooling or power supply is required beyond the supplied cable.
