Dell Inspiron 15, 3000 series. OS 8.1
Using a TV as a second screen, to when streaming a program, the Laptop Screen switches over to screen saver mode after about 10 minutes, so I have to sweep the touch pad to restore the picture both on Laptop and external screen (TV). How do I prevent this from happening.
(On my Laptop the 'screen-saver', mode is a blank screen.)
