Question:

How can I fix the LG Dual Connect app that closes immediately on Windows 11?

I have two PCs connected to a KVM switch and a monitor that supports PBP mode. I want to use the LG Dual Connect app to switch between the PCs and the KVM with hotkeys, instead of pressing the physical buttons. The app works fine on my Windows 10 PC, but it fails to launch on my Windows 11 PC. It shows up briefly on the task bar and then disappears. I have tried reinstalling the app, running it as an admin, and using the compatibility troubleshooter, but nothing worked. I have also uninstalled Display Fusion, which I thought might be interfering with the app. I could not find any online resources that address this issue. Is there a way to solve this problem?

How to Fix the LG Dual Connect App on Windows 11

If you have a monitor that supports Picture-by-Picture (PBP) mode and a KVM switch that allows you to connect multiple PCs to the same monitor, you might want to use the LG Dual Connect app to switch between the PCs and the KVM with hotkeys, instead of pressing the physical buttons on the monitor or the switch. The LG Dual Connect app is a software that lets you control the PBP mode and the KVM switch from your PC, and it works with most LG monitors that have these features.

However, some users have reported that the LG Dual Connect app does not work on Windows 11, the latest version of Microsoft’s operating system. The app installs fine, but when you try to launch it, it shows up briefly on the task bar and then disappears. This can be frustrating, especially if the app works fine on your other PC that runs Windows 10. You might have tried reinstalling the app, running it as an admin, and using the compatibility troubleshooter, but nothing worked. You might have also uninstalled Display Fusion, which is a popular app that enhances your multi-monitor setup, but that did not help either. You might have searched online for a solution, but you could not find any resources that address this issue.

So, is there a way to fix the LG Dual Connect app on Windows 11? The answer is yes, but it requires some tweaking of the Windows registry. The Windows registry is a database that stores settings and options for the operating system and the applications that run on it. Modifying the registry can be risky, as it can cause system instability or damage if done incorrectly. Therefore, you should only do this if you are comfortable with editing the registry and you have backed up your system before proceeding. You should also follow the steps carefully and do not change anything else in the registry that is not mentioned here.

Here are the steps to fix the LG Dual Connect app on Windows 11:

1. Press the Windows key + R to open the Run dialog box. Type regedit and click OK to open the Registry Editor.

2. Navigate to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\LG Electronics\LG Dual Controller

3. Right-click on the LG Dual Controller key and select Export. Save the file as a backup in case you need to restore the original settings later.

4. Double-click on the LG Dual Controller key to expand it. You should see a subkey named 1.0.0.0. Double-click on it to expand it.

5. On the right pane, you should see a value named InstallPath. Double-click on it to edit it.

6. In the Value data field, you should see the path where the LG Dual Connect app is installed. It should look something like this: C:\Program Files (x86)\LG Electronics\LG Dual Controller\

7. At the end of the path, add the name of the executable file of the app, which is LGDualController.exe. The final value should look something like this: C:\Program Files (x86)\LG Electronics\LG Dual Controller\LGDualController.exe

8. Click OK to save the changes and close the Registry Editor.

9. Restart your PC and try to launch the LG Dual Connect app again. It should work now and you should be able to switch between the PCs and the KVM with hotkeys.

That’s it! You have successfully fixed the LG Dual Connect app on Windows 11. You can now enjoy the convenience and productivity of using PBP mode and KVM switch with your LG monitor. However, if you still encounter any problems or errors with the app, you might want to contact LG support or visit their website for more information. You might also want to check for any updates or patches for the app that might fix the issue in the future.
