LG B4 (2024)
Built-in far-field microphone
No TV micThis model has no built-in far-field microphone — voice control goes through the remote.
LG Digital Customer Care, via Best Buy Q&A: "does not have a built-in microphone on its frame." The budget tier this year — unlike the C4/G4 above it — has no far-field mic; the Magic Remote's near-field mic still needs a button press to talk.
Automatic content recognition (ACR), including over HDMI
Runs ACRThis model runs LG's ACR feature (branded "Live Plus"), which analyzes on-screen content — including over HDMI — to identify what's playing.
What ACR is and how to turn it off →
Source describes Live Plus generally on LG webOS TVs rather than confirming this specific model, but ACR has been a standard webOS feature across the lineup for years.
Scans your local network for other devices
Scans LANLike essentially all webOS sets, this model scans the local network for other devices. There is no settings toggle for this — the reported option is network-level (a guest network or VLAN, or disconnecting the TV from the internet and using an external streaming device instead).
How to put a TV on its own network →
Reported by Gamers Nexus and Level1Techs (2026) as webOS-level network scanning with no per-model settings toggle; described as platform-wide behavior rather than tied to a particular model.
Security vulnerabilities in webOS
SupportedThis model is still receiving firmware/platform updates.
What that actually means for your TV →
