LUOM TJ-A002 HDMI Switch 2×1 8K 60Hz 4K 120Hz 48Gbps Black

LUOM TJ-A002 8K HDMI Switch

The LUOM TJ-A002 is a compact 2-in-1-out HDMI switch designed for users who need to share a single 8K display between two source devices such as a gaming console and a PC. It supports video resolutions up to 8K at 60Hz and 4K at 120Hz with a maximum bandwidth of 48Gbps. The unit requires an external USB power connection to function and uses a simple push button to toggle between active inputs. Indicator lights confirm which port is currently selected.

Sustained 48Gbps bandwidth with USB power

When powered via the included USB-A to Micro-B cable, the switch maintains a stable 48Gbps link for extended sessions without signal degradation. The manual button press swaps sources in roughly one second, avoiding the handshake delays common with auto-switching models. Because the device draws power externally, it does not rely on the HDMI ports themselves for voltage, which helps preserve signal integrity over longer cable runs at 8K 60Hz or 4K 120Hz.

Passive cooling in a 70x51x13 mm alloy case

The aluminium-alloy enclosure measures 70 by 51 by 13 millimetres and weighs 60 grams, dissipating heat passively without any fan noise. In typical desktop use the housing remains barely warm to the touch, and the only audible sound is the tactile click of the selector button. Power draw is limited to what the USB 5V supply provides, so there is no measurable impact on system power budgets or thermal headroom.
