LG is facing renewed criticism after testing revealed that some of its premium gaming monitors can automatically install software on Windows PCs through Windows Update—without users explicitly approving the installation. The software then promotes McAfee security trials and requests broad permissions, sparking concerns about privacy, transparency, and user control.
The findings come from Gamers Nexus, which tested several LG UltraGear monitors and documented the behavior on Windows systems.
LG Monitor App Installer Appears Automatically on Windows
According to the investigation, connecting supported LG monitors—including the $1,200 LG UltraGear 34GX900A-B—can trigger Windows Update to automatically install an application called LG Monitor App Installer from the Microsoft Store.
The installation reportedly happens without a separate prompt asking for user consent, relying instead on Windows’ driver and device metadata system.
Once installed, the application can download additional LG utilities, including:
- LG OnScreen Control Plus
- Monitor management software
- Firmware-related utilities
While these tools are intended to enhance monitor functionality, the automatic installation process has drawn criticism because many users are unaware it is happening.
Broad Permissions Raise Privacy Questions
After installation, the LG software reportedly requests access to several Windows permissions, including:
- Internet connectivity
- System information
- Device management
- Location services
- Background operation
Critics argue that these permissions exceed what many users expect from monitor management software.
Privacy advocates also point out that users are rarely informed beforehand that these applications will be installed automatically.
McAfee Trial Ads Reportedly Appear After Boot
One of the biggest complaints involves advertising.
Testing found that the LG software can display McAfee antivirus trial promotions on nearly every Windows startup, effectively turning monitor companion software into an advertising platform.
Many users consider this behavior similar to bundled adware because:
- It appears automatically.
- It promotes third-party software.
- It cannot be easily avoided unless the installer itself is blocked.
LG OnScreen Control Plus Linked to Anti-Cheat Issues
Gamers also raised concerns about LG OnScreen Control Plus.
According to the report, the software monitors certain system activity to provide display-related features. Some users claim this behavior has triggered anti-cheat systems used by competitive multiplayer games.
Although there is no evidence that the software is malicious, unexpected background activity can sometimes resemble the behavior of unauthorized overlays or monitoring tools, leading to potential game restrictions.
LG webOS TVs Face Separate Privacy Backlash
The monitor controversy follows another criticism involving LG webOS televisions.
Recent software updates reportedly require users to accept terms stating they are responsible for obtaining consent from everyone whose voice may be recorded—including family members and visitors.
The concerns include:
- Voice recognition enabled by default on some devices
- Responsibility shifted to the TV owner
- Voice recordings potentially processed for AI features
The updated legal language has reignited debates around smart TV privacy and informed consent.
Users Can Block Automatic Installation
Windows users who do not want companion software installed automatically have several options.
Possible methods include:
- Using Group Policy to prevent automatic device metadata installation.
- Applying Windows Registry policies that block automatic driver and app installations.
- Removing the Microsoft Store application after installation if it is not needed.
These approaches may also prevent future automatic installations for supported LG devices.
Part of a Broader Privacy Debate
The latest controversy also revives discussions about LG’s previous privacy practices, including past reports involving smart TV data collection and advertising technologies.
While monitor companion software can provide useful features like firmware updates and display controls, many users expect:
- Clear installation prompts
- Optional software downloads
- Transparent permission requests
- No bundled advertisements
The incident highlights the growing concern over hardware manufacturers using Windows Update and companion apps to distribute software that extends beyond essential device functionality.
Final Thoughts
LG’s premium gaming monitors offer impressive display technology, but the automatic installation of monitor software—and the inclusion of McAfee promotional pop-ups—has generated significant criticism among Windows enthusiasts.
For users who prefer complete control over their systems, the ability for companion software to install through Windows Update without an explicit prompt raises important questions about user consent, privacy, and the future of device software distribution.
Whether LG changes this behavior in response to community feedback remains to be seen, but the controversy is already fueling broader discussions about how hardware vendors should deliver software to Windows PCs.
