Three-input HDMI 2.1 switch for multi-source setups
The ESTONE TJ-A113 connects three HDMI 2.1 sources to a single display, supporting 8K at 60 Hz and 4K at 120 Hz with 48 Gbps bandwidth. It suits owners of a console, a streaming stick and a PC who share one 8K TV or high-refresh monitor. The aluminium enclosure keeps all ports on one side for a tidy desktop. No driver installation is required.
Passive operation with optional power for best
The unit draws negligible power from the HDMI lines during normal switching and produces no audible noise. An external USB power supply is recommended by the manufacturer to reach full 48 Gbps performance at 8K 60 Hz or 4K 120 Hz. LED indicators show the active input at a glance. The IR remote works up to 26 ft without line-of-sight constraints.
Stable signal under continuous 8K
With a quality HDMI 2.1 cable and the optional power supply connected, the switch maintains 8K 60 Hz or 4K 120 Hz indefinitely without dropouts. Dynamic HDR, VRR and chroma 4:4:4 pass through unchanged during extended gaming or playback sessions. Manual or remote input changes take effect instantly. Automatic switching is not supported.

Questions about this item
How do I install the ESTONE TJ-A113 HDMI 2.1 switch and what is the step people often miss?
Connect up to three source devices to the three HDMI 2.1 inputs and one display to the single HDMI 2.1 output, all on the same side, then attach the included power supply — the step many skip — and use the manual button or IR remote to select the active port.
What maintenance or replacement will the ESTONE TJ-A113 need over time?
The unit itself has no user-serviceable parts; long-term reliability depends on using certified 48 Gbps HDMI 2.1 cables for 8K 60 Hz or 4K 120 Hz signals, so replace any cable that shows intermittent dropouts or fails the bandwidth test.
What limit appears first during sustained 8K 60 Hz or 4K 120 Hz use?
The 48 Gbps bandwidth ceiling is the first hard limit; pushing 8K 60 Hz or 4K 120 Hz with full chroma subsampling requires every cable and connected device to sustain that rate, otherwise the switch will fall back to a lower resolution or refresh rate.
