Monitor driver

Our agency has a Dell Vostro 1500 laptop running Windows XP Pro SP3 that is
having some monitor problems. Ever since I have connected a projector to it
the monitor has intermittantly been using the resolution of 1024x768 and
becoming darkened (very dark but readable) despite the brightness being set
to 100%. The monitor is WXGA and should have a resolution of 1280x800 and
obviously should be much brighter. When I am having the problem, I have
checked the Device Manager and there are three monitors listed and all three
are named "Digital Flat Panel (1024x786)." I uninstall all of these monitors
in Device Manager, reboot the machine, and they all reappear again and the
resolution is still 1024x768 and the screen is darkened. With no rhyme or
reason it will suddenly go back to the correct resolution and brightness
after a reboot. Not every reboot, just whenever it choses. Sometimes the
1024x768 and darkened screen will last for days despite many reboots. Since
it is not my computer, I have not had the opportunity to go into Device
Manager to see what the monitor is named and how many are listed when it is
working properly. In Windows Display Settings, two monitors are listed; 1.
Digital Flat Panel (1024x768) on Mobile Intel(R) 965 Express Chipset Family,
2. (Default Monitor) on Mobile Intel(R) 965 Express Chipset Family. The
(Default Monitor) allows many more resolution options. How do I get rid of
the Digital Flat Panel (1024x768) monitor driver and get it changed to
(Default Monitor) so that I can get this user back to a brighter and easier
to read screen? Thanks for any assistance.

Download and install the latest video card driver and utility from the
manufacturer of said video card.

http://downloadcenter.intel.com/Prod...=2800&lang=eng

It's a laptop - two possible outputs usually - therefor you are *not* going
to get rid of the second monitor capability. ;-)

If downloading/installing the latest driver from the graphics chipset
manufacturer (above) does not remedy the issue - consider it (as you
indicated with your post in this group_) an actual hardware failure and
contact Dell to have it looked at and the proper parts replaced. It
*really* sounds hardware related ( intermittent issue? Drivers, unless they
have a conflict with something you only use occassionally, rarely cause
intermittent issues. ;-) )

You can test further as well - just create and boot from a BartPE or
Ultimate Windows Boot CD. Does the screen exhibit the same symptoms?

What about the possibility it is just "bad karma" in the registry ?

The problem with reinstalling drivers, is the registry may not get corrected
in the process. Whatever bad settings may have been stored in the registry,
the driver reinstallation isn't likely to remove them. (I've heard of
people trying that, in cases where the display resolution setting,
was higher than the monitor could handle, and the driver reinstall
in safe mode wouldn't fix it.)

Attacking the problem, from the registry, is probably the way to fix it.
But who knows those registry hives in enough detail, to give an
absolutely correct recipe for deletion, so they won't continue to
cause problems ?

Part of the problem could be due to the extent to which the display
devices properly support Plug and Play. A projector probably
doesn't have an EDID. I don't know if there is a guarantee
that every laptop LCD panel properly registers itself. If
every device had an EDID, then there would be reduced odds
of screwed up settings in the registry.

This tool is free, and can print the EDID to the screen.
It might give some idea, as to whether the LCD panel of
the laptop, has information to offer.

If booting from a clean Windows XP install (essentially) exhibits the same
symptoms... Then it is likely a hardware issue. If not - the software
could still be a concern.

And installing the latest driver could clear up a software issue safely as
well.

Maybe I didn't get my point across very well. I see
three problem piles...

1) Broken hardware. Symptoms are the result of hardware
that is not functioning correctly.

2) Broken driver. Issue is isolated to the driver.
Problem magically disappears when a newer driver is installed.
Or, a corrupted file is removed, due to the uninstallation of
the previous driver, properly cleaning up after itself.

3) Registry entry, or a settings file, still sitting in the
system, contains context information that will prevent
the problem from being fixed. This is the problem I
was referring to, where the user can reinstall drivers
"till the cows come home", and the symptoms persist.

I can give an example of (3).

*******
I had two sound devices. When the second sound device was added
to the system, it added a necessary registry entry for itself.

The second device was removed at a later date (as its installation
was an experiment). The uninstallation did not remove the
registry entry it added.

When the first device was selected as the sound device, the
Mixer control panel would disappear and not be usable.

Now, it wouldn't matter how many times I reinstalled either
device (I tried that). A registry entry the second package added,
prevented the first package from running correctly. The first package,
on seeing the registry entry, thought the second package
mixer was being used.

I managed to fix this myself, by using Sysinternals tools,
and seeing the Mixer application of the first device,
reading a particular registry entry. Once I found the particular
registry entry, I removed it manually. And voila, I have
a working mixer.
*******

So I'm suggesting, that there could be a registry problem,
that won't be corrected by reinstalling the graphics driver.

It's a laptop - two possible outputs usually - therefor you are

If downloading/installing the latest driver from the graphics

Part of the problem could be due to the extent to which the display
devices properly support Plug and Play. A projector probably
doesn't have an EDID. I don't know if there is a guarantee
that every laptop LCD panel properly registers itself. If
every device had an EDID, then there would be reduced odds
of screwed up settings in the registry.

This tool is free, and can print the EDID to the screen.
It might give some idea, as to whether the LCD panel of
the laptop, has information to offer.

If booting from a clean Windows XP install (essentially) exhibits
the same symptoms... Then it is likely a hardware issue. If not -
the software could still be a concern.

And installing the latest driver could clear up a software issue
safely as well.

they boot with the BartPE/UBCD and don't have the problem - it's likely
software and could be what you say, could be fixed in the manner i say,

So - I still say their best bet is to find out if it is hardware or
software. Your 2 & 3 are both software issues - so there are two

Boot with the CD mentioned, does it work? If so - it's possibly a hardware

It's a laptop - two possible outputs usually - therefor you are
*not* going to get rid of the second monitor capability. ;-)

If downloading/installing the latest driver from the graphics
chipset manufacturer (above) does not remedy the issue - consider
it (as you indicated with your post in this group_) an actual
hardware failure and contact Dell to have it looked at and the
proper parts replaced. It *really* sounds hardware related (
intermittent issue? Drivers, unless they have a conflict with
something you only use occassionally, rarely cause intermittent

You can test further as well - just create and boot from a BartPE or

The problem with reinstalling drivers, is the registry may not get
corrected in the process. Whatever bad settings may have been
stored in the registry, the driver reinstallation isn't likely to
remove them. (I've heard of people trying that, in cases where the
display resolution setting, was higher than the monitor could handle, and
the driver reinstall
in safe mode wouldn't fix it.)

Attacking the problem, from the registry, is probably the way to
fix it. But who knows those registry hives in enough detail, to
give an absolutely correct recipe for deletion, so they won't continue to
cause problems ?

Hi Guys,
I am certainly a little less tech savoy than you seem to be, but I am having
the EXACT same problem as Mike. I am running Windows XP on a Toshiba laptop.
The only difference is that I found that as far as the brightness goes, it
is backwards...tell it to get lighter and it gets darker. BUT...the three
monitors continue to install themselves and when I found out I could delete
them and get it towork properly, I thought that I could just deal - but I am
getting REALLY annoyed with having to delete them each time! So, Mike, did
you find a fix? Or can someone tell me in a little simpler terms what to do?

Thanks,
Katie
