What that actually means for your TV →

Roku OS updates are pushed by Roku across Roku TV-licensed hardware generally, but no dated, model-specific commitment or current update record for this exact Onn model could be found, unlike Samsung's public seven-year Tizen commitment. Stays unverified rather than assumed either way.

This model has Onn's ACR feature (branded "Smart TV Experience"), which analyses on-screen content — including over HDMI — to identify what's playing.

What ACR is and how to turn it off →

This model is documented by Onn as a Roku TV. Roku's current guide says Smart TV Experience uses opt-in ACR on live TV and HDMI or AV inputs and names Settings > Privacy > Smart TV experience > Use info from TV inputs as the opt-out — the same system and setting used across every Roku TV-licensed brand on this site.
