CPU Maxed by DisplayLink Processes for HP Pavilion Desktop

I’m been using the USB 3.0 with a HP 2000 laptop (with USB 2.0) for several years. Using a USB switch I added an old HP Pavilion Desktop (Dual core Pentium CPU-also with USB 2.0). Both systems have the newest 9.2 M3 DisplayLink software. The laptop continues to work with no problems. All the peripherals connect ok for the desktop (monitor, keyboard, mouse, etc) but Task Manager shows that the Display Link processes are causing the CPU to work at 100% CPU usage which, of course, seriously impacts all other programs, the mouse etc. Any suggestions for fixing this CPU usage problem would be appreciated.


Thanks for contacting us! I am sorry this is not working as expected.

The DisplayLink software relies on the computer’s graphics controller to drive the external displays, if the graphics are not supported or incompatible with the DisplayLink software it may be offloading some of the work to the CPU which can severely affect performance.

Based on your description of the behavior, our first step is to get some additional information from your system.

If you would, please keep the dock connected to the desktop and attach the output of our diagnostic utility PlugDebug ( http://plugable.com/support/plugdebug ) to an email to ‘support@plugable.com’ with the subjectline ‘Ticket #322543 - Attention Pat’ as this will allow us to examine some log files from your system to help determine if the system is compatible with this docking station and will point to our next steps.

Thanks for the response. I’ve downloaded the plugdebug program. Unfortunately, I won’t again have access to the HP Pavilion until the weekend. I’ll run he program then and send in the results next Monday. FYI: The system runs Windows 7-x64 and the video card is Nvidia GeForce 7100/NForce 630i. It seems IN THE PAST there have been issues between DisplayLink drivers and some Nvidia drivers:
Although I have the “latest” Nvidia driver, it, like the system is rather old !
Hope we can get this resolved !!

Thanks and regards,


Hi Micah,

Thank you for the update, I look forward to hearing from you on Monday. Please let me know if there is anything else I can do to help in the meantime.

Have a great day!
