Monitor goes to sleep when screen has lot of black.
Hello,
First of all, I can't remember when and how this started, but definitely after upgrading from Windows 8.1 to Windows 10 Pro.
So, my screen (Acer LCD, connected to GTX 560 with 1 meter DVI cable) started going black (power light on, background light completely off) when I watched a video that had lot of dark on it. Happens in some games as well where the cut scenes change.
I tested it by full screening a plain black image and the screen went to sleep, mouse cursor dissapeared.
Moving the mouse does not wake up the screen, only when i press Win key to bring up some color to the screen. (the task bar seems to be enough to wake the screen.)
I have checked all the power settings and turned off all the sleep settings, 'Turn off display after' is set to 'Never'
'Multimedia settings' are set to ' Prevent idling ' and 'Optimize video quality'
What is happening?
Edit: Nvidia driver version is 355.60
