Multiple monitors on Intel IEGD driver

[lovelyshadeofgreen]

Hello again everyone,

I am coming to the end of a very long image building process and the
spec has now changed (as usual).

I have built an image (its on a Commell LV673 motherboard with Intel
915GM graphics) and it is working with a VGA monitor and a TV
composite out running as an extended desktop, at present.
I've now been told that the customer doesn't want the monitor plugged
in all the time and will only be installing with a TV on his sites.
He wants the TV to display as the primary but not be the primary as he
doesn't want the error messages to show (and some other silly reasons
- but hey he is a customer).
I've tried using the IEGD driver from the Intel website and it works
after you tell it to be the right settings in windows but as soon as
you reboot it forgets the settings. (I have disabled the ewf at this
point).
It starts off as though it is going to work but then flicks and stops
outputting to the TV again.
You can re-enable it but it forgets every time on reboot.
I've tried this driver on a normal xp pro machine and it works fine
but still doesn't solve the problem of making the VGA primary and work
but not be there and everything display to the TV which is there.

I'm running out of ideas - Help!

Lucy.

IEGD has a number of strange behaviours when it comes to auto detection of
connected monitors on power on and automatically disabling them if not
found. Most of this can be controlled by modifying the VBIOS be editing the
resource settings and recompiling. This process is described in the IEGD
documentation.

An easier way could be to use ChangeDisplaySettingsEx API call to adjust the
monitors to your liking on start-up. I have done this successfully using
CRT+LVDS combination on 852GME & 915 chipsets and it seems a reasonably
robust way of getting the job done.

Stuart
