Hi JASON12345,

 

I might suggest that you can try to update your machine's display driver from the recommended drivers on support site. On the support page, enter your machine serial number to load up the drivers, go to Drivers and Software tab, click on Manual Update then download-install the display drivers.

 

You may also check if the issue reported would be present in safe mode.

 

I hope this helps.

 

Regards.
