Will not recognize external monitor

Dell Inspiron running Windows 7. I was able to run two monitors without a problem and now all of a sudden it is no longer recognizing my external monitor

Hi Stacy,

Thank you for contacting us, we’d be glad to help! It would be very helpful if you could capture and send us the DisplayLink log file, it gives us detailed information on how your system is setup and helps us narrow down the problem. Step by step instructions on how to collect this log file can be found here:

You can send the zip file to support@plugable.com and we’ll take a look!

Thanks,
