The Elusive LG KVM App: Troubleshooting Sudden Closures on PC


“I’m encountering a problem with the LG Dual Connector KVM application. On my work laptop (PC1) with Windows 10, which connects to the monitor via USB-C Thunderbolt and Display Port, the software installs and runs without issue. However, on my gaming PC (PC2) with Windows 11, connected through two HDMI ports, the application installs and prompts a reboot, but upon trying to launch it, the app appears briefly in the taskbar and then shuts down immediately. I’ve already attempted uninstalling a potential conflicting application, ‘Display Fusion,’ and running the LG app as an administrator, as well as using the compatibility troubleshooter, but the issue persists. Is there any known solution or troubleshooting steps that could resolve this problem of the app closing automatically?”


If you’re experiencing an issue where the LG Dual Connector KVM application closes immediately after opening on your Windows 11 gaming PC, despite functioning correctly on your Windows 10 work laptop, you’re not alone. This can be a frustrating problem, especially when you’ve taken steps to resolve it, such as uninstalling conflicting software and running the application as an administrator. Here’s a step-by-step guide to help you troubleshoot this perplexing issue:

: Ensure that both your Windows 11 operating system and the LG Dual Connector KVM application are up to date. Sometimes, compatibility issues can be resolved with the latest patches and updates.


Review System Requirements

: Double-check that your gaming PC meets the minimum system requirements for the LG Dual Connector KVM application. Although it’s a gaming PC, certain specifications might be crucial for the app’s operation.


Inspect Event Logs

: The Windows Event Viewer can provide clues as to why the application is closing. Look for error logs around the time the app crashes to identify any system or application conflicts.


Disable Startup Applications

: Other applications that run at startup could interfere with the LG software. Use the Task Manager to disable startup applications temporarily to see if this resolves the issue.


Reinstall the Application

: Uninstall the LG Dual Connector KVM application completely, then reinstall it. Sometimes, a fresh install can fix unexpected bugs.


Check for Driver Conflicts

: Outdated or conflicting drivers, especially graphics drivers, can cause applications to close unexpectedly. Update your drivers to the latest versions available.


Run in Compatibility Mode

: Although you’ve tried the compatibility troubleshooter, manually setting the application to run in compatibility mode for an earlier version of Windows might yield better results.


Create a New User Profile

: A corrupt user profile could be the root of the problem. Create a new user account on your PC and try running the application from there.


Contact LG Support

: If all else fails, reaching out to LG customer support can provide you with more specific guidance and potential solutions.

Remember, while troubleshooting, it’s essential to make one change at a time and test the application after each step. This methodical approach will help you pinpoint the exact cause of the problem. Good luck!

This article aims to provide a comprehensive approach to resolving the automatic closure issue with the LG Dual Connector KVM application on a Windows 11 system. If you’ve tried these steps and the problem persists, it may be worth exploring community forums or contacting LG for further assistance. Sometimes, issues like these can be unique to specific hardware configurations, and collective wisdom or official support might offer the solution you need.
