What it does and who it's for

The LUOM TJ-A140 is a 4-in-1-out HDMI 2.1 switch that routes four source devices to one display. It targets gamers and home-theatre users who own multiple consoles or PCs and a single 8K or high-refresh 4K screen. Buyers who need to send one source to several displays cannot use this unit.

Bandwidth and resolution limits

The switch passes 48 Gbps and supports 8K at 60 Hz, 4K at 120 Hz and 1080p at 144 Hz or 165 Hz. HDCP 2.3 and HDR10+ are handled, and deep-colour modes up to 12-bit with 4:4:4 chroma are available. Long cable runs beyond the spec's reach may reduce the maximum refresh rate.

The spec that decides fit

Four HDMI 2.1 inputs and one HDMI 2.1 output are provided, so the part only fits setups with exactly four sources feeding one screen. Power comes from a USB-C 5 V/1 A port and switching is done by button or IR remote.

Questions about this item

Should I pick the 8K@60Hz or 4K@120Hz mode for my display?

The switch passes both 8K at 60 Hz and 4K at 120 Hz simultaneously; choose the resolution and refresh rate that your monitor or TV supports, and the unit will forward it without conversion.

What does the 48 Gbps bandwidth actually deliver on my screen?

The 48 Gbps HDMI 2.1 link carries uncompressed 8K 60 Hz or 4K 120 Hz video with HDR10+, 10- or 12-bit colour and 4:4:4 chroma, so you see full gaming and cinema quality.

Which HDMI version limits what I can connect?

All five ports are HDMI 2.1 with HDCP 2.3, so any 2.1 source — PS5, Xbox Series X, 8K media player or 4K 120 Hz PC — works at its native spec.
