Seems quite random... I saved "15 minutes" monitor off time from KDE, checked with "xset -q" that it was:
DPMS (Energy Star): Standby: 900 Suspend: 900 Off: 900 DPMS is Enabled Monitor is On
But after log out and log in there was this:
DPMS (Energy Star): Standby: 54000 Suspend: 54000 Off: 54000 DPMS is Enabled Monitor is On
