I have a Gigabyte 7VM400M - RZ motherboard and am running XP Pro. I
have changed the monitor to a BENQ 900W wide screen but it would seem
that the screen is not being detected by Plug and Play.
Only "Default Monitor" is shown and I cannot adjust the resolution to
the wide screen resolution. The monitor came with a CD containing
drivers and instructions on how to load the drivers but in the Device
Manager window there is no entry for Display adapter or for Monitor so
there is no means of loading drivers.
How can I get the new screen recognised and the driver loaded.
Is that the G900W ? 1440 x 900 ?

The user manual mentions a "monitor driver", but their web site
doesn't offer one for download. Better check for a CD that came
with the monitor for that.
ftp://12.145.38.159/monitor%2flcd%2fmanuals%2fg900%5fg900w%5fg2000w%2epdf
This is an example for another monitor, the FP93G. Benq doesn't
seem to be putting drivers on their FTP site for newer monitors.
What you would try, is right click on the INF file in the ZIP,
and select "install" as the option. Install might be the option
right under the highlighted "open" option (at least on Win2K it
is).
ftp://12.145.38.159/monitor/lcd/drivers/fp93g/FP93G.zip
Before installing the driver, you can also try this.
To test to see whether the EDID monitor information is coming
across the DDC serial link inside the monitor cable, try this
tool.
http://www.entechtaiwan.com/util/moninfo.shtm
Normally, the information on the EDID, should be enough to
identify the monitor. If the Entechtaiwan tool can see the
monitor, then there should be a page of returned info.
Installing the monitor driver, does a couple things. It
usually sets a registry entry, for max resolution. It
also installs the ICM file, which presumably has some
color management information. (Something that Photoshop
might consult.) It allows making gross color corrections
for the tendencies of the monitor. For example, if the
monitor was "blue" by nature, then they could reduce the
blue a bit in Photoshop, to make pictures match the real
thing.
Nvidia and ATI have the capability to set a custom
resolution. Powerstrip from Entechtaiwan ($) can do
that. Nvidia, in the classic control panel, has a
custom resolution dialog. With ATI, there can be a
list of resolutions you can get to show up in a
menu. So there are ways to try to deal with it.
Powerstrip is for cases where all else fails.
So try the monitor driver first, and select "install"
when right-clicked on the INF on the driver CD.
