Video passthrough support

Video passthrough support is robust in reviews that mention it, including HDR formats and Dolby Vision passthrough, making the HDMI inputs more useful for source devices.

Video passthrough support is repeatedly highlighted, with HDMI inputs that pass modern 4K/120 signals and common HDR formats, letting the bar act as an AV hub.

Video passthrough support is repeatedly called out for Dolby Vision and HDR10+ via the HDMI input, generally reported as limited to 4K at 60 Hz.

Reviews confirm broad video passthrough support including 4K, Dolby Vision, and HDR10, but not full HDMI 2.1 gaming features.

A recurring drawback is the lack of HDMI passthrough or HDMI switching. If your TV has limited ports, this can be a real usability constraint.

One review explicitly says the HDMI input does not support 4K passthrough.

There are no HDMI inputs, so it cannot act as an HDMI switch with video passthrough; it relies on the TV's eARC connection for sources.

With no dedicated HDMI input or true video passthrough path, the Smart Soundbar trails more AV-oriented competitors on source-routing flexibility.

There is no real video passthrough story here because the bar is treated as a basic ARC/optical audio endpoint rather than an HDMI switching hub.
