Plug in a new LG UltraGear monitor to a Windows 11 computer, and Windows will silently install an LG app and driver updates without asking you or showing any notification, according to testing by Gamers Nexus (The Verge). The app, called the LG Monitor App Installer, does not actually let you control your monitor. Instead, it points you toward LG's own apps and McAfee antivirus software.

The reason this happens is a Windows feature called Hardware Support Apps. Microsoft lets device makers pair an app from the Microsoft Store with their hardware, so that when you plug in a device, the matching app installs by itself (Microsoft Learn). It is similar to how your phone might automatically download a companion app when you connect certain headphones. Microsoft's own documentation says the automatic install "does not provide a notification to the user" and admits that some people will find it confusing and frustrating (The Verge). This is not just an LG thing. Dell does the same with its Alienware Command Center app when you connect an Alienware monitor (The Verge).

Gamers Nexus found that large pop-up ads for McAfee and LG apps appeared in the bottom-right corner of the screen on 31 out of 32 times they started up the computer (The Verge). Users first reported the issue on Microsoft's own community forum back in 2024 (The Verge).

The LG app's page on the Microsoft Store says it can "use all system resources" and "access your Internet connection" (Microsoft Store). LG's privacy policy, which you can reach from the installer, says the app automatically collects information about your device, your internet activity, and your location (The Verge).

If you have Windows Pro, you can stop these apps from auto-installing using a setting meant for IT administrators called group policy. If you have the standard Home edition of Windows, your only option is a toggle buried in Advanced system settings that turns off all automatic manufacturer app downloads (The Verge).

The broader context here is a tension that has existed in the Windows world for years. Microsoft created the Hardware Support App feature to make things easier: plug in a device, and the right software installs automatically so you do not have to go looking for it. That goal makes sense. But the same system that delivers a helpful app can also deliver advertising, and once a device maker decides what to include, there is no built-in difference between the two.

With LG, that line disappears entirely. The Monitor App Installer provides no monitor controls at all. It is essentially a launcher for other LG apps and McAfee, with a privacy policy that claims wide-ranging data collection. The pop-up ads on 31 of 32 bootups are not a glitch; they are what the app is designed to do. Someone who simply plugged in a screen is now seeing ads and sending data, with no prompt asking for permission at any step.

The permissions listed on the Microsoft Store make this worse. "Use all system resources" is a remarkably broad level of access for an app whose only real job is to point you at other apps. Add in the automatic collection of device data, internet activity, and location, and the installer looks less like a helpful tool and more like a permanent advertising and data-gathering program that rides in on a monitor cable.

Dell's Alienware Command Center uses the same Windows feature, though the available facts do not show whether Dell's app displays the same kind of advertising as LG's. What they share is that Windows gives device makers an automatic installation path with no notification, and each maker decides what to do with it. The only real limit on the system is a company's reputation.

In this author's view, the core problem is not that LG created an aggressive app, though it certainly did. The problem is that Microsoft built and maintains a system where skipping user notification is a deliberate, documented feature. Microsoft's own materials acknowledge that users will be confused and frustrated, yet nothing has changed. The fixes available to users put the burden on the person who plugged in the monitor, not on the manufacturer or on Microsoft.

The fact that these reports go back to at least 2024 and the behavior is still happening in mid-2026 suggests neither LG nor Microsoft sees it as something that needs fixing. For IT staff managing many computers, the group policy fix works fine. For the much larger group of Home edition users, that buried settings toggle is the only defense, and it blocks all manufacturer apps rather than letting you choose.

The Hardware Support App feature is not harmful by nature, and the plug-and-play convenience it provides has genuinely helped Windows users for years. But when an automatic, silent installation system is used to deliver ads and collect data instead of providing device features, the assumption that manufacturers will use it responsibly has been stretched. Microsoft gave them a door with no lock, and LG walked through it carrying advertisements and a data collection policy.
