How to disable screens turn off Windows 8.1

So recently my computer started turning my screen monitors off after a while without activity, if I move the mouse or hit the keyboard they turn back on. I just want them to stay on.

My System is windows 8.1 64 bit, I have 2 screens with mini display port and 1 television with hdmi which often is in regular television mode when this issue happens.

Now before you jump to conclusions this is what I've tryed:

• Disabled screen saver
• Power saving settings to high with following set:
  • Turn of the display: Never
  • Put the computer to sleep: Never
  • Turn off hard disk after: Settings: Never
  • Sleep: Sleep after: Settings: Never
  • Display: Turn off display after: Settings: Never
  • Display: Enable adaptive brightness: Settings: Off
  • Multimedia settings: When sharing media: Settings: Prevent idling to sleep.

Any pointers that get me in the right direction will be greatly appreciated.

Solution 1:

I found this post that worked for me. It says:

at first you must set value of "Attributes" = dword: 00000002 in [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\8EC4B3A5-6868-48c2-BE75-4F3044BE88A7] , and then in "Power Options" - "Advanced Power Settings" in the "Display" item appears "Console lock display off timeout" in which we set the necessary time.

Hope it helps.
