Solution

It is not possible to turn off the display and leave the computer on. If you wish to reduce the energy use of the display, use the Energy Saver control panel to adjust the time before the display goes to sleep.

To allow the display to sleep separately from the computer, follow these steps:
    1. Open the Energy Saver control panel.
    2. Click Sleep Setup.
    3. Click the checkbox to turn on "Separate timing for display sleep."
    4. Drag the slider to select the time for display sleep.
    5. Close the Energy Saver control panel.
