A TV connected to a laptop or console over HDMI feels like a dumb screen. But a recent investigation of LG sets found there’s a lot more going on behind the glass. Researchers caught the TV scanning the home network, identifying connected devices, and fingerprinting what was playing over HDMI for advertising. In a staged security test, a compromised TV even recorded audio from an HDMI conference call while offline, then sent it out once it was back online.
The unsettling part isn’t only what the TV can collect, but how much trust is buried in its setup and permissions. Optional tracking is blended in with the agreements you actually need, while the highlighted “Select All” button makes saying yes to everything the easiest route. We dig into what the investigation found, which settings are worth changing, and how far DNS protection can help when your TV gets a little too curious.
