StudioWhy smart TVs are cheap: @Tristan0x shares a guide to disabling ACR tracking and blocking it with DNS filtering
Original title: If you've ever wondered why smart TVs are so cheap, this is why.
Citing @log4j's rooting of a Samsung TV, the author reports always-on hot mic, automatic content recognition (ACR), geolocation, network mapping and user profiling shared with Samsung's 400 partners; ACR screenshots the screen every 500ms on Samsung and 10ms on LG, and can fingerprint devices over HDMI or borrow mics from soundbars. The guide offers three steps: turn off ACR per brand (Samsung's Viewing Information Services, LG's Live Plus, etc.), isolate smart devices on a guest/IoT network, and apply DNS-level filtering with NextDNS or Pi-hole on the router while blocking outbound port 53. It notes Vizio lost $6.7M selling TVs in Q3 2024 while making $115.8M gross profit from ads and viewing data, paid $2.2M to the FTC in 2017, and Texas sued Samsung, LG, Sony, Hisense and TCL over ACR.
The post gives concrete menu paths for disabling ACR across TV brands plus DNS-level blocking steps readers can follow directly to protect their privacy.
