HDMI 2.1 passthrough is the headline upgrade, enabling 4K/120Hz and gaming features for consoles/PCs; most sources call it a meaningful addition, with rare reports of port-specific issues.
Multiple reviewers emphasize passthrough is not HDMI 2.1 and does not support 4K/120. Recommended workaround is to connect consoles directly to the TV and use eARC for audio back to the bar.
There is no HDMI 2.1-style gaming passthrough here, and reviewers explicitly flagged the lack of an HDMI input as a drawback for console-focused setups.
There is no evidence of HDMI 2.1 gaming support, and reviews specifically frame connectivity as basic ARC-only TV hookup rather than advanced passthrough.
