Sorry for the (very) delayed response. NoDDC set to true or false has no effect. The monitor is powered off with all combination of this option with either or both of the PanelSize and MonitorLayout commented out. NoDDC set to true or false with both PanelSize and MonitorLayout enabled result in a working monitor. Regards, Roger -- .''`.
