LUOM TJ-A125 3-Port HDMI 2.1 Switch
The LUOM TJ-A125 is a three-input, one-output HDMI 2.1 switch designed for users who need to connect multiple 8K-capable sources to a single display. It suits home-theatre enthusiasts and gamers running consoles such as PS5 or Xbox Series X alongside a media streamer or PC. The compact aluminium housing keeps the desktop tidy with all ports on one side.
Front-panel button and LED indicators
A single push-button cycles through the three connected devices, while LED indicators show which input is active. This lets users change sources without unplugging cables or reaching behind equipment. The switch passes compressed audio formats including Dolby Atmos, DTS Digital and Dolby Digital, so surround sound remains intact when switching between a Blu-ray player, console and streaming box.
48 Gbps bandwidth for 8K@60 Hz and 4K@120 Hz
The switch delivers up to 48 Gbps throughput, enabling 8K resolution at 60 Hz and 4K at 120 Hz with Dynamic HDR and HDCP 2.3. This bandwidth figure is the decisive spec: if your display and source cables support HDMI 2.1, the TJ-A125 will pass the full signal without compression. Builders needing more than three inputs or automatic switching should look elsewhere.

Questions about this item
Will the HDMI 2.1 ports need replacement from repeated plugging?
The three HDMI 2.1 inputs and one output are rated for standard mating cycles; no user-serviceable parts exist inside the aluminium shell.
What bandwidth ceiling appears first during a long 8K@60Hz session?
The 48 Gbps HDMI 2.1 link is the hard limit; sustained 8K@60Hz or 4K@120Hz uses the full pipe so cable quality becomes the bottleneck.
Does the aluminium case stay cool when the switch runs all day?
The alloy shell acts as a passive heatsink; with no active components drawing high power it remains near ambient temperature during continuous use.
