In the past few weeks when the monitor (Dell S2440L) enters the power saver mode(PSM) after 5 minutes of non use, and I move the mouse to bring it out of PSM , the existing page that was on screen when it entered PSM is frozen and does not respond to the mouse movements( Mouse works but does not control functions on the page until I click another tab page then I can go back to the non responsive page and it is now responsive ? Could this be a Windows 10 problem or something else ? Any Ideas?
