In September 2026, the YouTube channel Gamers Nexus — best known for hardware reviews and testing methodology — released a sprawling, 135-minute investigative report into LG smart TVs that has since rattled the consumer electronics world. Produced alongside the channel Level1Techs and a team of independent security researchers, the investigation dug into what LG's televisions actually do on a home network, and the findings go well beyond the kind of targeted-advertising tracking that smart TV owners have grudgingly come to expect.
The headline claim: audio capture in standby mode
The most explosive finding is that LG TVs may be able to capture audio even when the set looks completely off. Gamers Nexus says its researchers were able to record audio through an LG television while it was in a hibernation state — meaning that even with the TV's own microphone switch disabled, other microphones associated with the device, such as the one built into the remote, might still be active.
The investigation's framing of the scale of this issue produced its most viral number. Extrapolated out, Gamers Nexus put the figure at roughly 216 million "spy TVs" in the United States alone.
A more detailed breakdown of the report clarifies an important nuance in this claim: the TVs aren't necessarily recording while genuinely powered off at the wall. According to that reporting, LG smart TVs can capture microphone audio in standby mode after a remote's power button is pressed — not while the set is truly powered down — and researchers demonstrated audio continuing to be stored even while the TV was disconnected from Wi-Fi, with that audio later retrievable once connectivity resumed. In other words, the concerning behavior isn't that a dead TV is listening — it's that "off" via the remote doesn't mean the microphones and local storage stop working, and audio can sit buffered on the device until it reconnects and uploads.
That distinction has fueled a wave of short-form videos and a trending hashtag online. Clips demonstrating this behavior spread under tags like #unplugthetv, with people posting reaction videos of themselves unplugging their televisions at the wall. The reporting consensus that crystallized around this is blunt: fully unplugging the set from power is the only way to guarantee the hardware is inert, since turning it "off" with the remote — or even pulling the network cable alone — isn't sufficient on its own, because the audio is buffered locally and simply waits for the next reconnection to upload.
Network scanning: mapping your entire household
Beyond audio, the investigation focused heavily on how aggressively LG TVs probe the rest of a home network. Network packet captures reportedly showed the televisions scanning local networks for nearby devices such as phones and smartwatches, and collecting information including location data and nearby Wi-Fi network details — with some of that information transmitted onward to LG Ad Solutions, LG's connected-TV advertising business.
Other outlets that reviewed the report describe a similarly broad sweep. Firmware analysis and packet captures reportedly showed the tested TVs identifying a wide range of devices on the local network — phones, PCs, printers, network switches, and smart-home hardware — while also collecting nearby Wi-Fi network names, signal information, and device identifiers, effectively building a picture of everything else connected in a household.
A separate summary of the same findings adds a further wrinkle: this network mapping isn't limited to moments when the TV is actively streaming. Rather than confining network communications to streaming traffic, the televisions were said to routinely catalog other hardware on the same local network at all times, logging internal IP addresses and unique device identifiers for equipment like smartphones, PCs, printers, and other IoT devices.
Automatic Content Recognition (ACR): watching what you watch
A large part of the story isn't a secret hack — it's LG's own advertising technology working as designed, just far more expansively than most owners realize. Automatic Content Recognition (ACR) is the industry-standard technique smart TVs use to identify what's on screen: it samples what appears on or is heard through the TV, creates a digital fingerprint of that content, and compares it against a reference database to identify programs, ads, and viewing habits.
Gamers Nexus's report argues LG's implementation of ACR is unusually broad in scope, extending well past streaming apps and cable. Investigators found LG was using ACR not only to track viewing habits across streaming platforms and cable, but also to monitor content played through nearly every physical port on the TV — HDMI, USB, ethernet, optical, RCA, and coaxial. That means content from a game console, a Blu-ray player, or even an old cable box plugged into an HDMI port could, in theory, be fingerprinted and logged the same way a Netflix stream would be.
Coverage of the report also notes this practice is not unique to LG — using ACR to track content this way is described as an industry-wide norm among nearly all major smart TV manufacturers, not a problem limited to LG alone. What set LG apart in the investigation, according to multiple outlets, was the sheer volume and specificity of data allegedly being collected and combined with network and device data for advertising purposes.
What LG's own advertising arm says about itself
Perhaps the most unsettling material in the investigation isn't a hacked packet capture at all — it's LG's own marketing. The report reportedly pulled footage from promotional materials produced by LG's ad-sales division, in which representatives describe knowing who is present in an "LG household" and which devices are there. For critics, that framing — a TV manufacturer's advertising unit boasting about household-level visibility into who lives where and what devices they own — is as damning as any technical vulnerability, because it suggests the data collection is a deliberate business strategy rather than an unintended side effect.
Security vulnerabilities on top of the data collection
Separately from LG's intended data-collection features, researchers say they also found genuine security weaknesses in the TVs' software that could make things worse if a set were ever compromised. The investigation reported extensive device and network discovery, ACR tracking, and security weaknesses that could increase the consequences of a compromised television, while noting that some findings concern LG's intended product behavior and others rely on vulnerabilities still being responsibly disclosed to the company.
Reporting on the technical side of the story indicates the team held back the most sensitive exploit details as a matter of standard security practice — full details of the remote-code-execution flaws they found were withheld while disclosure to LG was still underway, in line with typical industry norms.
Not LG's first brush with this kind of criticism
Notably, this wasn't the first time Gamers Nexus had raised alarms about LG's data practices. Earlier in 2026, the channel reported that several popular LG gaming monitors were automatically installing a Windows application without users' permission, with the monitors also reportedly collecting user data and serving pop-up ads for McAfee antivirus software. That episode reportedly drew a response from Microsoft, whose executive vice president of Windows and Devices later confirmed the company intervened and forced LG to remove the app from the Windows Store following user backlash over the pop-ups and silent installations.
Korean-language coverage of that earlier monitor controversy adds independent testing detail: across 32 consecutive system reboots, researchers reportedly saw a pop-up promoting a McAfee trial appear 31 times, presented as a default recommended option nearly every time.
LG's response: denial, with caveats
LG has pushed back firmly against the most serious allegations while acknowledging that data collection is occurring in some form. The company issued a global statement disputing reports that its TVs log ambient conversations while turned off and harvest large volumes of consumer data, describing the coverage as contributing to "misconceptions" about how its devices work — while still acknowledging that some data collection does take place.
On the specific question of when microphones are active, LG's position is narrower than the "always listening" framing that spread online. According to the company's statement, its TVs only process voice data when a user presses and holds the voice-control button on the remote, or when a wake word is detected after a user has manually enabled a far-field voice recognition feature. Outside those two triggers, LG says the TV does not collect or record ambient conversations, and any audio that fails to match the wake word is processed locally and deleted immediately rather than sent to a server.
On the network-scanning findings specifically, LG has offered an explanation rooted in ordinary product functionality rather than covert surveillance. Independent fact-checking of the coverage found that most outlets agree LG smart TVs do scan local networks to identify nearby devices like phones and smartwatches — a capability LG describes as a standard function supporting features like screen casting.
On the advertising-tracking side, LG has pointed to an existing opt-out rather than disputing that ACR tracking happens at all: the company has denied that its microphones record ambient conversations while confirming that ACR is used to track viewing habits for advertising, and has directed users to the "Live Plus" setting as the way to opt out.
One notable gap in LG's public defense, according to reporting on the statement, is what it left unaddressed: one of the most serious allegations circulating — that voice commands are stored on LG's servers unencrypted — reportedly went unmentioned in the company's official response.
There's also a numbers discrepancy worth flagging. While the original investigation's 216-million figure describes U.S. devices specifically, LG Ad Solutions materials and the investigation itself reportedly cite up to 363 million "addressable secondary devices" globally — pointing to a potentially vast footprint of household data being used for advertising purposes worldwide.
A pattern of friction with the press
LG's handling of this kind of scrutiny has reportedly extended beyond public statements. According to Australian outlet ChannelNews, LG Electronics Australia previously restricted media access for publications that ran critical reporting on its data practices, after those outlets declined a request to retract earlier stories about LG's use of ACR technology to track viewing habits across broadcast channels, streaming apps, and connected devices like game consoles and PCs.
Sorting fact from amplification
As with most viral tech-investigation stories, the online reaction has run ahead of some of the underlying nuance. A few points worth keeping in mind:
- Network scanning for nearby devices is confirmed and largely undisputed. LG doesn't deny it happens, and frames it as a feature (device discovery for casting), not a bug.
- ACR-based viewing tracking is real, industry-wide, and opt-out-able. LG's Live Plus setting is the mechanism, though it's reportedly on by default on many sets and buried in menus.
- The "listening while off" claim is more specific than the headlines suggest. It centers on standby-mode behavior after the remote's power button is pressed, and on locally buffered audio, rather than a genuinely powered-down television actively transmitting audio in real time.
- The most serious unresolved question — whether voice data is stored unencrypted on LG's servers — remains disputed, since LG's public statement reportedly didn't address it directly.
- Independent verification is still ongoing. The disclosed vulnerabilities are still working through responsible-disclosure channels with LG, meaning some technical details remain unconfirmed by outside parties.
What LG TV owners are being told to do
In the wake of the report, the practical advice circulating from security-focused coverage is fairly consistent: treat a smart TV like any other computer on your network. Recommendations include disabling ACR/Live Plus in the settings menu, reviewing and revoking voice-recognition permissions, segmenting the TV onto its own isolated or guest network so it can't freely scan other household devices, and — for the most privacy-conscious owners — disconnecting the TV from the internet entirely and using an external streaming device instead, one whose permissions can be controlled more granularly.
The bigger picture
Whatever the final technical details turn out to be once independent researchers and LG's own disclosure process catch up with the initial report, the Gamers Nexus investigation has reignited a debate that's been simmering for over a decade: smart TVs are, functionally, advertising and data-collection platforms that happen to also display video — and most owners have no real visibility into how much of their home network, viewing history, and even ambient audio is being logged along the way. As one piece of coverage on the story put it, the real takeaway may be less that any single company is uniquely predatory, and more that this is simply what connected devices do by default now, with LG's particular implementation collecting an unusually large amount of it.
