The display port/miniport driver pair uses the Display Data Channel (DDC) protocol to read the monitor's EDID over the I☬ bus, which is a simple two-wire bus built into all standard monitor cables. With a database of more than 2,150,000 drivers, ASR will not. ASR is a tool that removes all of the complications and wasted time when updating your Monitors manually. When the monitor function driver receives a request to retrieve the monitor's EDID, it sends a request to the display port/miniport driver pair that is represented by the physical device object (PDO) at the bottom of the monitor's device stack. Automatic Driver Updates for Acer Monitors: Recommended: ( Download ASR) (recommended for Windows) users who are inexperienced in manually updating missing/out-of-date drivers. A request, from a user-mode application, to read a monitor's EDID is processed by the function driver (Monitor.sys) in that monitor's device stack. Those services include exposing a monitor's identification data and (in the case of an ACPI display) setting the brightness of the display.Ī monitor stores its identification and capability information in an Extended Display Identification Data (EDID) structure, a format that lets the display supply the host with information about its identity and capabilities independent of the communications protocol used between the monitor and host. User-mode applications use WMI to invoke the services of the monitor class function driver.

The following table shows the device stack for a video output that has a connected monitor. For integrated monitors, such as the built-in flat panel on a laptop computer, there might be a filter DO, associated with the Advanced Configuration and Power Interface (ACPI) driver, above the PDO. In some cases, there is a filter DO, associated with a vendor-supplied filter driver, above the FDO. Typically, there are only two device objects in the device stack that represent a (video output, monitor) pair: the physical device object (PDO) and the functional device object (FDO). Each video output on the display adapter that has a monitor connected to it is represented by a device node that is a child of the display adapter's device node.
