TCL's budget 4K LED keeps it simple with three HDMI 2.0 ports capped at 4K@60Hz — HDMI 1 carries eARC for a soundbar or receiver. Unusually for a 2024 set, it retains a 3.5mm composite AV input and a separate 3.5mm headphone output alongside optical audio. A single USB 2.0 port, Ethernet and an ATSC tuner with RF antenna round out the connections. There's no HDMI 2.1 here, so gaming tops out at 4K@60Hz.
