Questions about this item
Will the 3.5 mm audio jack or the USB 3.0 ports need periodic replacement after heavy daily switching?
The 3.5 mm audio output and four USB 3.0 ports are solid-state interfaces with no moving contacts, so they do not wear out from normal switching; only the push buttons or remote could see mechanical wear over very long use.
What is the first limit reached when all four computers push 8K60 or 4K120 video continuously through the single HDMI output?
The HDMI output bandwidth caps at the 8K60 or 4K120 specification, so sustained multi-source traffic will hit that video-throughput ceiling before the 5 Gbps USB 3.0 channels become a bottleneck.
How much heat or fan noise does the unit produce when powered by the 12 V adapter and running all day with four active PCs?
The 10 × 5 × 2 cm enclosure has no fan and draws power only from the 12 V DC adapter; it runs silently and stays barely warm during continuous operation with four computers connected.
