Dell SE178WFP manual Power Management Definition, Pin Assignments

If you have VESA's DPMS compliance display card or software installed in your PC, the monitor automatically reduces its power consumption when not in use. This is referred to as Power Save Mode. If input from keyboard, mouse or other input devices is detected by the computer, the monitor automatically resumes functioning. The following table shows the power consumption and signaling of this automatic power-saving feature:
