Primary Display Not Recognizing Mouse Click

I’ve noticed some really strange behavior where my primary display stops responding to mouse clicks unless I press the windows key and leave the start menu up. I’m using Plugable USB 3.0 to DVI adapters. I have three total, but only the primary acts up. The issue is sporadic and I can’t seem to identify the cause. I’ve verified it’s not the mouse by trying a different mouse as well as different USB ports for the mouse. Any thoughts?

Hi Patrick,

Thanks for reaching out to us, I am sorry this strange behavior is happening.

Based on your description this may be a software issue where one piece of software is taking the mouse focus and preventing the mouse clicks from being registered in Windows. By opening the start menu Windows is taking focus back. I doubt this is physically related to the USB graphics adapter, however swapping the adapter used with the affected screen with another adapter would rule out the hardware if the issue continues.

I don’t think this is a driver issue but to rule it out we can perform a reset of the adapters and ‘clean’ install of the graphics drivers to help ensure both are in a good state. Please perform the following:

  1. Disconnect the USB Graphics Adapters from the system so they turn off completely (this is important so the units reset). Please keep them disconnected until the last step.
  2. Uninstall any and all software with ‘DisplayLink’ in the title that is present from within the Control Panel -> Programs and Features. Don’t worry if these entries are not present or if the process does not work, just move onto the next step
  3. Download and run the DisplayLink Installation Cleaner utility, found here --> https://s3.amazonaws.com/plugable/bin… and ensure it displays “Cleaning Complete” when done (video walk-through if you need it -> https://youtu.be/AcVV1gD_FvI)
  4. Once the Cleaner has been run, reboot (even if not prompted to)
  5. Now download and install the 8.3 M1 DisplayLink software, found here --> https://s3.amazonaws.com/plugable/bin…
  6. Reattach the USB Graphics Adapters to the system. If the devices are not detected, please reboot the system.

You may need to re-enable extended desktop modes and re-position the displays after completing the ‘clean’ driver installation.

Please let us know if that helps get things working how they should, and we’ll go from there.
