# dpms(4freebsd)

VESA BIOS DPMS driver

## NAME

**dpms** – VESA BIOS DPMS driver

## SYNOPSIS

**device dpms**

## DESCRIPTION

The **dpms** driver uses the VESA BIOS to manage an external display during suspend and resume. When the machine suspends, the **dpms** driver turns the external display off. When the machine resumes, it restores the display to its state when the driver was first loaded.

## SEE ALSO

[acpi\_video(4)](/acpi_video/4.md)

## 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.
