LG TV Shown Scanning LAN for Third-Party Devices

LG TV LAN Scanning Sparks New Privacy Questions

LG TV LAN scanning has ignited a privacy firestorm. After a YouTube investigation revealed that the company's televisions are probing home networks for nearby devices even when the set appears to be off, the backlash was swift. It's a startling discovery. Gamers Nexus, working alongside Level1Techs and a team of security researchers, dug deep into how LG's televisions handle data collection behind the scenes, and what they found isn't sitting well with anyone. So the question now is simple: what else don't we know about?

Packet captures documented everything. The investigation relied on them to expose what the TV was really doing, and Gamers Nexus' editor-in-chief confirmed that the device actively scanned the local network, uncovering a range of connected hardware that most users wouldn't expect. But that's not all. It's a clear breach of trust, and they're not hiding it. So the evidence speaks for itself.

"The [G5] crawled our entire network and found dozens of unrelated devices, including smartwatches and phones of our staff who didn't even know we were working on this," Burke said.

That detail matters. The devices found were not paired with the TV. They were not actively streaming to it. They simply existed on the same local network, and the TV took note of them anyway.

What the TV Actually Sees

They grabbed Wireshark, a network protocol analyzer, and tore through the TV's firmware to see exactly what data it hoards. The results are unsettling. And what they found stretches far beyond the simple act of spotting a device on a network, revealing a sprawling, invasive picture that goes much deeper than anyone initially suspected. It's a lot.

According to the investigation, LG TVs are capable of identifying:

• Your IP address and geographic location
• The name of every Wi-Fi network in the vicinity
• Signal strength and channel numbers of neighboring Wi-Fi networks in range
• Other devices on the network, even if not connected to the TV in any way
• The internal IP address of other devices on the network

That last point is worth pausing on. The TV is not just looking for devices that want to connect to it. It is cataloging everything that happens to be sharing the network, from laptops to smart home gear to phones that have never interacted with the television.

LG Ad Solutions has publicly claimed in its marketing materials that it can reach 363 million "addressable secondary devices" across the US.

That number now carries a far heavier meaning. But given what the investigation actually uncovered, it's hard to see that statistic as anything other than a red flag, a figure that once seemed like a simple measure of scale now looking less like reach and more like exposure. It's a stark shift. The same digits don't tell the same story anymore.

LG's Response

When reached for comment, a company representative shared a statement from LG Electronics. The company framed the behavior as standard smart TV functionality.

"LG TVs can identify compatible devices on the same network to enable features such as device connectivity, content sharing or smart home functionality," the statement read.

LG also confirmed that its TVs can scan for and connect to nearby devices on the same network, framing this capability as a standard function common to smart TVs and smart home devices. That's their claim. But here's the catch: the company didn't offer any specifics on how that scanning works or what safeguards exist. So it's a vague reassurance at best. They call it routine, yet the lack of detail leaves room for doubt.

Burke pushed back on that framing. It's not just about connectivity, he insisted, noting instead that the behavior is native to the TV itself and doesn't rely on any security flaws, so the problem runs deeper than a simple fix. And that distinction matters.

"This is the TV's native functionality. This didn't require vulnerabilities," Burke said.

The Dumb Monitor Problem

One of the more uncomfortable findings involves people who try to avoid smart TV tracking altogether by using the display as a dumb monitor. Burke suggested that approach may not offer the protection users expect.

"Even using an LG smart TV as a dumb monitor doesn't necessarily stop all of the functionality we're talking about today," he explained.

He also pointed to broader implications that extend beyond LG. Internet service providers sometimes run dual SSIDs, which include open neighborhood Wi-Fi broadcast from customer routers, and that's a practice that creates a hidden web of shared connectivity you might not even notice. Comcast's Xfinity neighborhood hotspot and AT&T's public hotspots operate this way. So devices can autoconnect to these open networks when discovered. It's automatic. Particularly in apartment buildings where neighbors use such routers, your phone or laptop may latch onto a stranger's signal without a single click from you, and that raises questions about who's really in control.

The result is a web of connectivity. It's getting harder to know what a TV is seeing or sending, and that blurring of boundaries between the device in your living room and the data streams it touches raises questions we can't easily answer. Burke put it bluntly: this is a concern broadly speaking and future looking for smart TVs regardless of the brand. So don't expect that uncertainty to vanish anytime soon.

Listening While Offline

The investigation also demonstrated something that will unsettle many owners. The researchers captured microphone audio while the TV was unplugged from the network entirely.

Burke said the audio was reportedly stored locally in plaintext. That creates a potential pathway for data to reach LG later, if the TV reconnects to the internet and the stored audio is transmitted.

Level1Techs representative Wendell Wilson offered a blunt observation about the economics of this kind of data hoarding: "It doesn't cost a lot to store text forever."

LG responded to these claims directly. The company said that when the TV is in standby mode, it only monitors for a wake word if the user has previously enabled the Far-Field feature. If no wake word is detected, the audio used for wake word detection is processed locally on the TV, promptly deleted, and not transmitted to LG servers.

The statement added that LG TVs don't collect, record, or transmit ambient conversations in your home. That's clear enough. But they only do this unless voice functionality has been intentionally activated by the user, and even then, the company insists that audio processing happens only when that same voice functionality has been activated and a wake word such as "Hi LG" is detected. So it's a narrow window. They've drawn a strict line.

The Reputation Gap

There is a reason this story is getting attention beyond the usual smart TV privacy concerns. LG has built a reputation in recent years as a premium brand with less aggressive advertising and tracking than budget competitors. That reputation now faces fresh scrutiny.

The timing does not help. Last month, LG monitors were found to be installing McAfee ads onto connected Windows PCs. That revelation, combined with the current findings, suggests a pattern of behavior that sits uneasily with the company's premium positioning.

The investigation also noted that remote code execution vulnerabilities are currently going through the disclosure process, which means the full scope of what these TVs can do may not yet be public.

What This Means for Owners

If you've got a smart TV in your living room, the practical questions start to feel deeply uncomfortable, especially when you realize how little you actually know about what your television is doing when it's not in use. Most people assume a TV that isn't connected to the internet isn't tracking anything. That assumption may be wrong. At least for LG's products, the investigation suggests it's a shaky one. So here's the real kicker: your device could be watching you even when you've told it to stay offline.

LG frames the scanning as a means to power connectivity features and smart home functionality. But the divide between what the company claims it does with the data and what its ad division says it can reach is wide enough to make anyone stop and think. It's a gap you can't ignore.

There is also the question of consent. Users who buy a TV and plug it into their network are rarely told, in plain language, that the device will catalog every phone, watch, and laptop in the house. That information sits buried in user agreements that most people will never read.

Whether LG sends all of this collected data to its servers, or whether some of it stays local for diagnostics, remains unclear. But the company hasn't denied that the collection happens. That's telling. And the marketing materials from LG Ad Solutions suggest there's commercial interest in knowing what else sits on your network, which means the data could be far more valuable than simple troubleshooting logs, reaching beyond your TV into the broader ecosystem of devices you've connected.

The investigation does not claim LG is breaking any laws. It does suggest the company is testing the boundaries of what consumers will accept from a device that sits in their living rooms, watching and listening, even when the screen is dark.

Frequently Asked Questions

What did the investigation by Gamers Nexus and Level1Techs reveal about LG TV LAN scanning?

The investigation revealed that LG TVs actively scan the local network for nearby devices, even when the TV appears to be off. The TV was found to identify various devices on the network, including phones and smartwatches of staff members who were not aware of the testing.

How does LG explain the LAN scanning behavior of its TVs?

LG frames the behavior as standard smart TV functionality, stating that LG TVs can identify compatible devices on the same network to enable features such as device connectivity, content sharing, or smart home functionality. However, the company did not provide specifics on how the scanning works or what safeguards exist.

What types of information can LG TVs collect according to the investigation?

LG TVs are capable of identifying your IP address and geographic location, the name of every Wi-Fi network in the vicinity, signal strength and channel numbers of neighboring Wi-Fi networks, other devices on the network, and the internal IP address of other devices on the network.

Why might using an LG smart TV as a 'dumb monitor' not fully protect users?

Burke suggested that even using an LG smart TV as a dumb monitor doesn't necessarily stop all the functionality discussed, implying that the LAN scanning behavior is native to the TV. This means the TV could still engage in network scanning and data collection even if not used as a smart TV.

What did the investigation find about microphone audio on LG TVs when they are offline?

The investigation captured microphone audio while the TV was unplugged from the network, and it was reportedly stored locally in plaintext. This creates a potential pathway for data to reach LG later if the TV reconnects to the internet and the stored audio is transmitted.
