programmatically controlling two monitors with Intel IEGD drivers

[Guest]

We have an XPe system using the Intel 945GM graphics chip. Our app and system
are designed to work with two monitors. The second monitor is a DVI monitor.

We would like to programatically control whether the second monitor is
active or not and, when active, programmatically setting it to Extended
Desktop mode.

Currently, we are using the non-embedded version of the Intel Graphics
Driver (14.27) in which case these settings are controlled by user
interaction with the Intel Graphics Panel GUI. This driver is installed
after FBA.

I have downloaded the Intel IEGD_v8.0 - this package allows one to build an
embedded graphics sld. I've been looking thru the IEGD User's Manual but so
far I have seen no reference to programmatically controlling display mode
settings including activation of a second monitor. Does anyone know whether
this is even possible or is user interaction again required with this
embedded version of the driver.

Thanks,

Art

This is a really good question. Why is it that seldom do the questions that
would provide some real insight into useful applications get answered?

It depends on functionality you are looking for.
Attaching a second monitor programmatically can be done with ChangeDisplaySettingEx Win32 API. For instance, see the code sniplet

If you want to programmatically control the monitor you should probably do so with the regular driver instead of the embedded driver. The embedded driver is more for have a certain configuration that doesnt really change. All of you outputs (DV0, DV1, LVDS, etc..) should be configured at the time the driver loads.

The regular driver on the other hand has the control panel program that makes calls through its .dll to set the displays. It would probably be easier for you to figure out how to make the same calls silently rather than mess with the embedded driver.
