Driver updates for Windows 10, along with many devices, such as network adapters, monitors, printers, and video cards, are automatically downloaded and installed through Windows Update. You probably already have the most recent drivers, but if you'd like to manually update or reinstall a driver, here's how: Update the device driver. This firmware and driver package contains drivers for all of the components in the Surface Pro 3, as well as updates to the system firmware that have been released via Windows Update. These drivers and firmware are compatible with Windows 8.1 and Windows 10, including Enterprise versions. This package provides Camera Driver and is supported on ThinkCentre Tiny-in-One 27 Monitor and running the following Operating Systems: Windows 10 (32-bit, 64-bit). For Acer monitors that have features that are not supported by the Windows PnP driver, you can download the driver from our Drivers and Manuals section. These driver packages include the following types of files.inf - Supplies Windows with the make, model, and resolutions your monitor can run.icc - Supplies Windows with information on the. I am not able to get my dual monitors running. I just performed a fresh install; these monitors were running just fine with my other hard drive and windows. I checked my display drivers in the Device Manager and there is only one driver listed under Display Adapters. ATI Radeon HD 3800 series.
-->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.
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). In some cases, there is a filter DO, associated with a vendor-supplied filter driver, above the FDO. 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.
The following table shows the device stack for a video output that has a connected monitor.
Device object | Required/Optional | Driver |
---|---|---|
Filter DO | Optional, typically not needed | Filter driver supplied by monitor vendor |
FDO | Required | Monitor class function driver (Monitor.sys) supplied by Microsoft |
Filter DO | Required only for integrated ACPI display panels | ACPI driver (Acpi.sys) supplied by Microsoft |
PDO | Required | Bus driver (display miniport/port pair) supplied by display adapter vendor |
User-mode applications use WMI to invoke the services of the monitor class function driver. Those services include exposing a monitor's identification data and (in the case of an ACPI display) setting the brightness of the display.
A 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. 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. 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. The display port/miniport driver pair uses the Display Data Channel (DDC) protocol to read the monitor's EDID over the I²C bus, which is a simple two-wire bus built into all standard monitor cables.
The EDID can be obtained using the ACPI_METHOD_OUTPUT_DDC method whose alias is defined in Dispmprt.h. This method is required for integrated LCDs that do not have another standard mechanism for returning EDID data.
For more information about communication between display adapters and monitors, see the following topic:
For details about EDID structures and the DDC protocol, see the following standards published by the Video Electronics Standards Association (VESA):
Enhanced Display Data Channel Standard (E-DDC)
Enhanced EDID Standard (E-EDID)
You can download these standards from vesa.org in the Free Standards section.
For details about the I²C bus, see the I²C Bus Specification published by Philips Semiconductors.
