Notes & Compatibility
HDMI: 4x HDMI 2.1 (40Gbps, 4K@120Hz, VRR, ALLM on all 4 ports). eARC: HDMI 2. USB: 3x USB 2.0 Type-A. G-Sync, FreeSync Premium. LG’s C3 spec sheet lists DTS:X as by-pass only, so the set does not decode it: send it to a receiver over eARC on HDMI 2, because optical TOSLINK cannot carry it at all. The same sheet lists QMS among the HDMI 2.1 features, which removes the black-screen blink when a source changes refresh rate — but only when the source and every cable in the chain support it too.
