All three of these modes seem to have the same effect on my display. Same blanking and waking time. Are there any differences in power consumption or something else?

1 Answer 1


On an LCD display, there is probably no difference between the different DPMS modes, which are really specified for CRTs.

From Saving Power on idle PCs:

… for an LCD display there is often no difference between standby, suspend, and off.

    I found a difference. Standby is the only mode which actually displays an image after I power cycle the monitor manually via its power button. The other modes, Suspend and Off, just remain blank/black when I restart the monitor, even when I move the mouse or press a key. So there's a difference. At least this is the case on my Linux installation.
