How to turn of the display in Windows 8 without locking or making computer go to sleep ?

The problem is that when I enable ‘Turn off display after x minutes’ feature from control panel, the device goes into sleep after ‘x’ minutes. It seems that both the options – turn off display/put computer to sleep are connected. It devices goes automatically to sleep mode as soon as the display is turned off. So, is there any method to turn off the display of the device without it going into sleep mode ?

Someone wrote in the microsoft forum " The whole key to this problem seems to be the "Turn off the Display" setting. If you have that set to 5 minutes, 10 minutes, 15 minutes, etc...the computer will go to sleep one minute after you lock the screen. With this setting set to "Never", it doesn't do it. So something is wrong there."

I want to turnoff the display but don't want to lock the device. Is that also possible ?

Thanks
