If the image is from the extended desktop. If so try moving the mouse from the primary display (the laptop LCD) off the sides and see if that shows on the other display.
Dell windows 10 OS laptop does not work correctly when hooked up to an external monitor through the VGA port. The external VGA cable works good on other laptops. When connected to the problem laptop, the external monitor shows a frozen picture of the desktop but will not change to another current view as other views are selected (ex. open email inbox or opening an MS office application). We have restarted the laptop and rechecked the VGA connection many times to no avail.
Q) What could causing this external VGA connection frozen image when connected and what could be the fix?
Thank you so much for any assistance/suggestions provided!
