By sensing the absence of video signals and one or both
sync signals coming from the host computer, it will reduce
power consumption as follows:
Power consumption
resumption time
≤ 140 W (TN-1885T)
≤ 150 W (TN-2185T)
≤ 100 W
approx. 3 sec.
≤ 15 W
approx. 3 sec.
≤ 5 W
approx. 10 sec.
0 W
The monitor requires a videocard or screen saver software
which switches off one or both sync signals to activate the
power saving function.
