LG has come under fire for what is effectively adware installed automatically when connecting certain monitors to a Windows PC. According to an investigation by Gamers Nexus, as reported by Videocardz, the South Korean manufacturer silently downloads and installs an application that triggers persistent pop-up ads promoting McAfee antivirus subscriptions. The issue is particularly controversial given that one of the affected monitors retails for over $1,000.

How the silent installation works

The software, dubbed LG Monitor App Installer, is downloaded and installed the moment a compatible LG monitor is plugged into a Windows machine. No consent is requested, and users are not given a straightforward way to opt out. Once installed, the app generates pop-ups advertising McAfee subscriptions, interrupting workflow. The discovery was made while testing the LG UltraGear 34GX900A-B monitor, but similar behavior was observed with the older LG UltraFine 32UN880-B, indicating a widespread practice rather than a one-off incident.

Affected models and community backlash

The two confirmed models are the LG UltraGear 34GX900A-B, a high-end gaming monitor priced above $1,000, and the LG UltraFine 32UN880-B, a professional display launched roughly three years ago. The tech community has reacted with strong criticism, emphasizing that expensive hardware should not serve as a vehicle for invasive advertising. Similar to recent revelations about software security, such as the Purdue study revealing US military apps containing Chinese and Russian code, LG's move raises serious concerns about consent and user trust.

Privacy implications and user trust at stake

This incident underscores the lack of transparency in how hardware companies handle software installations. Automatically deploying adware without notifying users violates trust and may breach consumer protection regulations. Moreover, using McAfee — a security product — as the source of pop-ups is ironic: antivirus software is meant to protect from threats, not become one. LG has yet to release an official statement, but growing backlash may force the company to remove the software or make it optional. For more context on similar threats, readers can refer to the Wikipedia entry on adware.
