Use This call provides a means for software to determine which DPMS state will be used when the screen is blanked. This will either be the DPMS state that was specified in the [[MDF]], or the DPMS state that was extracted from the EDID. h4. Notes This information is of an informative nature; the preferred way for software to blank and unblank the screen is via the [[ScreenBlanker]] SWIs, which do not require the DPMS state to be specified (the kernel, which is ultimately in charge of calling [[GraphicsV 4]], will remember the DPMS state that was specified in the [[VIDC control list]] that was used during the last mode change). h4.
