Hi Matas,

When an operating system has been updated recently, some devices that were recently added or reconnected to your computer will not work properly due to hardware reset. It needs a driver update to let your peripherals run properly on your computer again.

Visit this link: Update drivers in Windows 10 to know how to perform a driver update for your device. Once you follow the steps from the link, Windows will be able to reinstall it automatically and will look for available resources if you are connected to the Internet.

Let us know if this works for you.

Thank yo for posting back. It seems that this issue is somehow connected to compatibility concern. We advise to uninstall and reinstall the Display driver and check the device manufacturer for updated driver that you can download.

If anything comes up, don't hesitate to get back to us anytime.
