+.Sh NAME
+.Nm dpms
+.Nd VESA BIOS DPMS driver
+.Sh SYNOPSIS
+.Cd "device dpms"
+.Sh DESCRIPTION
+The
+.Nm
+driver uses the VESA BIOS to manage an external display during suspend and
+resume.
+When the machine suspends,
+the
+.Nm
+driver turns the external display off.
+When the machine resumes,
+it restores the display to its state when the driver was first loaded.
+.Sh SEE ALSO
+.Xr acpi_video 4
+.Sh BUGS
+The VESA BIOS DPMS calls do not provide any way to identify a particular
+display or adapter to manipulate.
+As a result,
+this driver may have unexpected results on systems with multiple displays
+and/or adapters.
