How to "attach" multiple monitors without going to Display Properties ...

ChangeDisplaySettingsEx does not provide a means of "attaching" the second
monitor ... so far, the only approach I've been able to identify for that is
to go to Display Properties and manually attach the second monitor post-FBA.

Is there a way via an API call or other means, to attach monitors 2 - n
without going to Display Properties? I'd like to set it up so it happens
during FBA ... maybe an app that runs as an FBA Generic Command.

We're running an nVidia Quadro4 NVS 400. Eventually, we'll be driving 8
displays from each box.

Am I missing something?

Thanks,

Craig
 
It's understand that it supports more than one monitor ... it allows all
monitors' settings to be manipulated ... even those that have not been
attached. It's also possible to open windows and draw on unattached
monitors. What ChangeDisplaySettingsEx does not provide is access to the
control to actually "attach" the monitor. It only deals with the device
context within Windows. Our suspicion is that one needs access within the
driver to actually turn a video port on (aka "attach").

I have responed to your email.

You can use ChangeDisplaySettingsEx to attach and configure more than one
display.

Pure wish for me. You would need two graphic cards to do that. Graphic cards
that support two outputs behave differently.

You should examine ChangeDisplaySettingsEx more closer.

It does offer you to setup more then one display.
