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.

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. Paul |

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?
