Professional in my Dell Inspiron 7500 Notebook.

In Win 98Se I ran dual monitor extended desktop, 1400x1050 16 bit color
in both displays. It worked fine. I have come to be dependent on the
wide desktop, it's really a plus for me. I liked it so much that

I installed XP Pro in my Inspiron 7500, using the new Dell XP Video
XP works fine, but I found that the video driver doesn't work at
1400x1050! The new Dell driver for
XP on the 7500 does not support my desired extended desktop
configuration that I enjoyed with the previous driver under Win98Se.
The new driver supports
resolutions up to 1600x1200 for a non-extended desktop (single
monitor). However, whenever
the desktop is extended into the second monitor, both monitors go down
1024x768! A Dell
statement in the Dell forum indicates that Dell
does not support XP on a 7500, but the Dell driver download web pages
indicate that the R48642.EXE file was "Adding support for Windows XP".

Here's the Dell

attention to the Dell statement

Unfortunately, as described previously, this Dell R48642.EXE driver

resolution, even though Dell clearly
claims the file is compatible. The R48642.EXE file
installs Driver version 184.108.40.206.5795 ("5795") dated 4/17/2002.
Research on the web and in the Dell forums found two other drivers to
First, I tried the "5772" driver, courtesy of "stonent", a Dell forum
Here's a link to his page.
Even though this was an earlier version of the driver, it was a bit
However, I couldn't find a way to use 1400x1050 on both monitors of an
desktop configuration, what Win98Se provided.
The other driver I found was a Compaq driver, "5779" (links provided
below), that allowed me to get the
extended desktop working with 1400x1050 16 bit on each screen, finally
what I had in Win98Se. However, for the 1400x1050 resolution, the
monitor now must be the external CRT! The internal flat panel must be
extended part of the desktop. I can use the new configuration, but I
have no idea WHY this switch is necessary.
I cannot force the primary monitor back to the internal flat panel
monitor and maintain the 1400x1050 displays. This makes for a lot of
when I use the notebook without a second monitor, because everything is
on the monitor that isn't connected. By the way, Alt-space gives a
menu that allows "off screen" menus to be moved back on screen; a
but it is a real pain.
Using the Compaq driver, when I try to use the built-in flat panel as
primary display, then the desktop on the CRT display is "bigger than
monitor screen" and scrolls to show the "rest of the screen" when the
pointer is run to the edge of the display. You only see a (magnified)
of the desktop on the CRT screen. Not really a usable condition, so I
use it that way.
Further, I can't reduce the display resolution like I could with the
Win98Se driver. I would like to be able to switch to resolutions
larger characters, as I could in Win98Se. The Compaq driver seems to
work at 1400x1050 when the extended desktop is enabled. But at least
Compaq driver lets me upgrade to XP, even if I lose some capability.
Compaq, it's really appreciated!
The bottom line is that the Compaq driver, with an earlier version
number than the Dell driver, proves that extended operation
is possible with XP and with both monitors running 1400x1050. However,
the Dell XP driver works
fine at 1024x768 extended; above that it gives up. Why won't the Dell
work at higher resolutions?
Hopefully Dell will work with ATI to enable the higher resolutions in
the XP monitor like Compaq. Hopefully the Dell forum statement
and Dell will make an effort to fully support its customers who own
7500 notebooks and want to use them as I wish to use mine. However, if
doesn't intend to fully support XP on my Inspiron 7500, I'm really
in Dell; Is this is the support I can expect in five years for a new
system I buy today? Is Compaq (HP) doing better?
Having said that, here's how I installed XP Pro on my Dell Inspiron
using the Compaq extended desktop video driver. This write-up ignores
generic XP steps and ignores XP issues that don't specifically apply to
Dell Inspiron 7500. This is a bit convoluted, but it does work and it's
I've also found that this works if either the Dell R48642.EXE (5795)
driver or the
5772 driver are in place before running the SP18896.exe program to
5779 (see below).
First I did a clean install of XP Pro to a freshly formatted C
drive, and updated to add service pack 1 (and many other MS XP updates).
I set Display Properties to 1400x1050 24 bit color. One setting
was for both the internal (LCD) and external (CRT) monitors.
After the generic XP installation, here's the information about the
video adapter provided by Microsoft:
Properties|Settings|Advanced|Adapter|ATI RAGE Mobility-P
Note: Display Properties|Settings| only shows one monitor, not two.
Both monitors display the same information and the CRT (but not
the LCD) must be "scrolled" to display the entire screen.
I installed the (Compaq) ATI Driver v5779:
This is available at http://h18007.www1.hp.com/support/files/armada/us/download/11021.html
or at ftp://ftp.compaq.com/pub/softpaq/sp18501-19000/sp18896.exe.
This will get the file SP18896.exe. It is intended for a Compaq
Armada 500E, not the Dell Inspiron 7500.
I ran SP18896.exe to extract the files from the archive, then I
ran setup.exe, one of the extracted files.
After the installation of this driver, here's the information about the
