|does it turn off when the computer is at idle?or when ur doing work or moving ur mouse? bcz some monitors are directly set to turn off when pc is at idle or when downloading something and ur not moving ur mouse to check that.|
check the following:
-go to control panel>power options>then change when the display turns off\monitor sleeps (depending on ur operating system) then change to ur preferred time or choose never.
