Owners of LG UltraGear monitors are reporting the discovery of unauthorized software on their Windows 11 machines. Users have identified an application titled 'LG Monitor App Installer' that reportedly installs itself in the background without prompting for permission or user consent.

Quick Facts

  • Affected Devices: Various models in the LG UltraGear line, including the 34GX900A-B and 39GX950-B.
  • Software Behavior: The 'LG Monitor App Installer' automatically runs on startup and displays pop-up advertisements for third-party subscriptions, specifically McAfee Premium.
  • Data Access: Once installed, the application requests access to system resources, internet connections, geolocation, device data, and user credentials.

Reported Behavior and Findings

Recent investigations, including testing performed by Gamers Nexus, confirm that the software installs immediately following driver installation on Windows 11 machines. The application functions as a boot-level program, meaning it launches automatically when the computer starts. In testing, the app consistently displayed a 30-day free trial advertisement for McAfee Premium.

While bloatware has been a standard inclusion on pre-built computers for years, this appears to be the first instance of a third-party peripheral—specifically a monitor—installing adware to market software subscriptions. The application's permissions allow it to collect a wide range of personal data, including transaction history and contact information, though current reporting indicates no evidence that it is capturing visual data from the monitor's display.

Broader LG Privacy Concerns

This situation follows separate concerns regarding LG's data collection practices on the television side of its product line. Recent updates to LG's smart TV user agreements have included language regarding AI-based voice recognition. The terms place the responsibility on the user to obtain consent from third parties if their voices are captured by the device's microphones.

This shift in transparency follows a May 2026 settlement between LG and the Texas Attorney General, Ken Paxton. That agreement mandated that LG implement clear pop-ups for smart TVs to explain how usage data is collected and provide a simple method for users to opt out of viewing data collection.

If you own an LG monitor, you should inspect your list of installed applications and review your startup programs. If the 'LG Monitor App Installer' is present, it can be uninstalled manually. For users looking to prevent similar silent installations, modifying settings in the Local Group Policy Editor is an option, though this tool is not natively available in all Windows 11 editions.
