Three-source HDMI 2.1 switch
The ESTONE TJ-A125 is a unidirectional 3-in-1-out HDMI 2.1 switch that routes three source devices to a single display. It supports video resolutions up to 8K at 60 Hz and 4K at 120 Hz with a maximum bandwidth of 48 Gbps. The unit is intended for users who need to alternate between multiple consoles, media players or computers on one screen.
Build integration and cabling
All three HDMI 2.1 inputs and the single output are located on the same side of the aluminium enclosure, keeping cable runs tidy on a desk or in a rack. A front-panel button and indicator LEDs show the active source at a glance. The switch passes Dynamic HDR, eARC and HDCP 2.2 or 2.3 signals through without processing, so the connected display handles the final handshake.
Sustained-load behaviour
The 48 Gbps bandwidth ceiling is maintained across extended viewing sessions, allowing continuous 8K 60 Hz or 4K 120 Hz playback without compression artefacts. Audio formats including Dolby Atmos, DTS:X, DTS-HD Master Audio and Dolby Vision pass through transparently. The device is strictly one-way; it cannot distribute a single source to multiple displays.

Questions about this item
Does the 48 Gbps bandwidth hold steady when switching between three 8K sources all day?
The switch is rated for 48 Gbps across all three HDMI 2.1 inputs and the single output, so the full bandwidth remains available for 8K@60 Hz or 4K@120 Hz signals during continuous use.
Does the aluminium enclosure stay cool and silent during 24-hour operation?
The unit has no fan and draws minimal power; the aluminium shell passively dissipates the small amount of heat generated, so it runs silently and stays at a low temperature even with all three ports active.
Do I need to supply my own HDMI 2.1 cables and a USB power source for 8K@60 Hz?
Yes, three certified HDMI 2.1 cables for the sources and one for the display are required, plus a 5 V USB power supply (not included) to ensure reliable 8K@60 Hz and 4K@120 Hz performance.
