For some strange reason, Windows 10 will no longer turn off the monitor display. This is happening with only one of my computers and I have looked everywhere and every place I look, it is set to turn off display after 1 hr which is what I have it set to. Windows 10 is up to date and so is the video card and monitor drivers. I have not installed any new program in weeks and this problem has only just started. Does anyone have any ideas. Thanks.
