Power management modes
If you have a VESA DPM™ compliant display
card or software installed on your
computer, the monitor can automatically reduce its power consumption when
not in use. This is referred to as Power save mode*. If the computer detects input
from the keyboard, mouse, or other input devices, the monitor automatically
resumes to function. The following table shows the power consumption and
signaling of this automatic power saving feature:
