| Trouble with new display and Device Manager
I had trouble getting the right drivers installed for my Viewsonic LCD. Essentially I ended up booting up the machine with no drivers and Windows installed a Default Monitor. After finally getting the correct drivers installed on my computer the correct drivers where installed but the computer still thinks there's an unknown monitor attached to the machine and keeps recreating the Default Monitor at start-up. How do I fix this false detection of an unknown monitor ? |

| Re: Trouble with new display and Device Manager
The way the monitor is listed is not important... as long as your colors and resolution are OK, that's all you need to worry about. The settings for your *video card *are what you need to set...especially if it's a wide screen |

Allow it to install the default monitor, then go into Device Manager and mark it as disabled. Nvidia video card? They alway have "defaul monitor" listed. No big deal, leave it alone. Unfortunately when I search for a file"VS080114_I19.inf" it cannot be found on my hard drive. I think I successfuly converted to a Viewsonic monitor by pointing to "%VCDTS21367-1%" , the driver being used for my VP930b monitor but I still end up with two monitors, which I don't want. |

(1) Boot to Safe Mode (Hold F5 as you boot or CTRL for the Startup Menu) (2) "START, Settings, Control Panel, System, Device Manager tab" (3) Open the Monitors branch, & Remove all entries. Perhaps, FIRST, even in Normal Mode, note what is currently installed. That is... (a) D-Clk the monitor there for Properties, Driver tab. (b) Click the Update Driver button, then "Next". (c) Bolt "Display a list...", & click "Next". (d) Bolt "Show all hardware". Examine the two panes to see what is currently installed. That is likely what you wish to end up with, after step (4). (4) Boot to Normal Mode. Hopefully, the correct monitor will be rediscovered & installed & the other will be gone. |

| Re: Trouble with new display and Device Manager
That's what I was looking for, but I couldn't remember. I've seen technicians clear all devices and let the system rebuild from scratch. There were a lot of Plug & Play entries in Safe Mode view of Device Manager that were cleaned up but unfortuately that Default monitor is still being redetected. Perhaps the Display Adapter is the problem, maybe it remembers it has two monitors ? Should I remove it in the Device Manager first, and let the system rebuild before trying to remove the Default monitor ? |

| Re: Trouble with new display and Device Manager
Just to complicate things for you, here is my registry entry (non-PnP monitor): ====================================================== [HKEY_LOCAL_MACHINE\Enum\MONITOR] [HKEY_LOCAL_MACHINE\Enum\MONITOR\DEFAULT_MONITOR] [HKEY_LOCAL_MACHINE\Enum\MONITOR\DEFAULT_MONITOR\0001] "Capabilities"=hex:14,00,00,00 "InitMonitorPowerState"="0f" "HardwareID"="Monitor\\API761E" "ClassGUID"="{4D36E96E-E325-11CE-BFC1-08002BE10318}" "Class"="Monitor" "Driver"="Monitor\\0000" "Mfg"="MEA" "DeviceDesc"="Diamond View DV152" "ConfigFlags"=hex:00,00,00,00 ====================================================== I have a 15" LCD monitor attached to a PCI graphics card. Device Manager does not show a Default Monitor, only a "Diamond View DV152". FWIW, the DDC pins, which are required for PnP, are not present in my VGA cable. This is because I'm going through a KVM box and I have used an extension cable from an old non-DDC monitor. DDC allows the monitor to communicate its capabilities to the graphics card, thus providing PnP support. By disabling DDC, I effectively have a non-PnP monitor. |

Alright, then. That was all done right. I still am studying the stuff you posted earlier. I see nothing especially wrong yet, except for the gobbledygook in your Update Driver requestor & the fact this Default Monitor won't go. Have you tried deleting just the Default Monitor in the Registry...?... HKEY_LOCAL_MACHINE\Enum\MONITOR\DEFAULT_MONITOR (a) "START button, Run, RegEdit". (b) Click the plus sign to left of "HKEY_LOCAL_MACHINE". (c) Click the plus sign left of "Enum". (d) Click the plus sign left of "MONITOR" (e) Click "DEFAULT_MONITOR" in the left pane. (f) Select "Export Registry File" in the "Registry" menu. Have it create a ".reg" file. It will contain all the information of the Default Monitor. This can be used to restore it, if the need may arise. (g) R-Clk "DEFAULT_MONITOR" in the left pane, & select to delete it. Reboot-- are you rid of it? By default, when a ".reg" is clicked, it will Merge into the Registry. To alter the default behavior... (a) "START button, Settings, Folder Options, File Types tab". (b) Scroll to & click (highlight) "Registration Entries". (c) Click the "Edit" button. (d) Select (highlight) "Edit" in the window. (e) Click the "Set Default" button. Now, when you click a ".reg" file, it will open in Notepad for examination. To merge it into the Registry, R-Clk it & select "Merge". |

Right click MyComputer. Click "Properties" in the popup menu. Click the "Device Manager" tab. Expand "Monitors". Double click on the "Default Monitor" device listed to open its properties. Click the "Driver" tab > "Update Driver" button. Click "Next". Select "Display a list of all drivers in a specific location,......" and click "Next". Click the "Have Disk" Button. Click the "Browse" button and navigate to the Directory\Folder\VS080114_I19.inf file you found earlier. Select the VS080114_I19.inf file in the Left pane and click Ok > Ok > Next. Follow the prompts to finish installing the driver. |

| Re: Trouble with new display and Device Manager
Hi Warren, glad to hear that you are using hunches and that they are working out. It is a toss up as to which should be done first, removing items from the Device Mangler or nuking entire registry strings. Probably the best way would be to do the Device Mangler first and then wipe up what ever is left behind in the registry. OK we now may have a "ghost inf" situation. Particularly with modem inf files, Windows likes to keep a copy of the installed device at Windows\INF\Other folder and if a device's inf file is to be found in there - Windows will automatically install it as a matter of fact with no (normal) options allowed to the user. So double check your Other folder for monitor files and delete them if you want to force Windows to go looking for installation files anew. And it's my opinion that you still do - this time make sure the ICM file is in the same folder as the monitor's inf file where ever that may be. Of course now what I'm asking that you do is everything you have learned so far, remove items from the Device Mangler, then delete entire monitor registry strings, delete INF\Other files that pertain to your monitor and then Reboot to allow Windows to find and install everything correctly. The reason the registry did not build back the key in question is because it did not need to. Somewhere else in the registry was the old information anyway and Windows just used it as is. I do not know how this happens exactly but it may also be tied to the "Default" monitor that won't go away and/or that is not being removed from the Device Mangler and/or perhaps with the Enum monitor branch of the registry. When EVERYTHING is removed properly then you get your devices reinstalled anew and the registry written with that instance of reinstalled information - if there is no reinstallation then it should not be a surprise that the registry doesn't get written to. |

Yes I have made some progress. There was a copy of the VP930 Series.inf in the Windows\Inf\Other folder which I removed. I really have no idea where Windows finds the appropriate inf & icm files for my Viewsonic monitor, but it seems to install nicely since I installed the appropriate driver package from Viewsonic. Removing the Default Monitor & the VP930Series Monitor in Device Manager, cleaned out the HKEY_LOCAL_MACHINE\Enum\Monitor & HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Monitor keys for both monitors. Unfortunately upon reboot the Default Monitor came back. Your comments about a clean install intrigue me, but I'm a little confused as to how far I should go. To clarify this question I have posted all occurences of Default_Monitor & VSCE41B below. Clearly there are more occurences than simply the HKEY_LOCAL_MACHINE\Enum\Monitor & HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Monitor areas of the Registry.

That's okay guys, I'm going in armed with the big guns. First, I've backed up my hard drive with Norton Ghost, so I have a mirror image of my hard drive on a separate disconnected hard drive as baskup. Second I'm going to run Roxio Go Back, which allows me to undo any changes made to my active hard drive, 99.9999999% of the time. Well I deleted all Registry keys with references to Default_Monitor and VSCE41B (my Viewsonic monitor) The process cleaned out a few, seemingly unimportant items in the Registry with regard to monitors, namely: HKLM\Software\Microsoft\Windows\CurrentVersion\cfgmgr32\Phantom\3A\, HardWareKey, MONITOR\DEFAULT_MONITOR\PCI_VEN_1002&DEV_5961&SUBSYS_280117EE&REV_01_000800_ 1 HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Doc Find Spec MRU\, g, vsce41b*.* otherwise everything regenerated, including the Default_Monitor. Here's the list of regenerated keys currently on my system now: Data fields are: Key, Entry's name, Value HKLM\System\CurrentControlSet\Services\Class\Monitor\0001\, MatchingDeviceId, Monitor\Default_Monitor HKLM\System\CurrentControlSet\Control\ASD\Prob\{CF2524C0-29AE-11CF-97EA-00AA 0034319D}\, MONITOR\DEFAULT_MONITOR\PCI_VEN_1002&DEV_5961&SUBSYS_280117EE&REV_01_000800_ 1, N/A HKLM\System\CurrentControlSet\Control\ASD\Prob\{9B4E7760-3196-11CF-97EA-00AA 0034319D}\, MONITOR\DEFAULT_MONITOR\PCI_VEN_1002&DEV_5961&SUBSYS_280117EE&REV_01_000800_ 1, N/A HKLM\Enum\MONITOR\DEFAULT_MONITOR\, {KEY}, {KEY} HKLM\Enum\MONITOR\DEFAULT_MONITOR\PCI_VEN_1002&DEV_5961&SUBSYS_280117EE&REV_ 01_000800_1\, {KEY}, {KEY} HKLM\Enum\MONITOR\DEFAULT_MONITOR\PCI_VEN_1002&DEV_5961&SUBSYS_280117EE&REV_ 01_000800_1\, HardwareID, MONITOR\DEFAULT_MONITOR HKLM\System\CurrentControlSet\Services\Class\Monitor\0000\, MatchingDeviceId, Monitor\VSCE41B HKLM\System\CurrentControlSet\Control\ASD\Prob\{CF2524C0-29AE-11CF-97EA-00AA 0034319D}\, MONITOR\VSCE41B\PCI_VEN_1002&DEV_5961&SUBSYS_280117EE&REV_01_000800, N/A HKLM\System\CurrentControlSet\Control\ASD\Prob\{9B4E7760-3196-11CF-97EA-00AA 0034319D}\, MONITOR\VSCE41B\PCI_VEN_1002&DEV_5961&SUBSYS_280117EE&REV_01_000800, N/A HKLM\Enum\MONITOR\VSCE41B\, {KEY}, {KEY} HKLM\Enum\MONITOR\VSCE41B\PCI_VEN_1002&DEV_5961&SUBSYS_280117EE&REV_01_00080 0\, {KEY}, {KEY} HKLM\Enum\MONITOR\VSCE41B\PCI_VEN_1002&DEV_5961&SUBSYS_280117EE&REV_01_00080 0\, HardwareID, MONITOR\VSCE41B |

| Re: Trouble with new display and Device Manager
The terminology "clean install" is used elsewhere so your attempt at kidnapping it for your own use will be frowned upon, kinda like saying "reverting your hard drive" when you should have mentioned re-imaging your hard drive with Go Back program instead. It makes you sound a bit off in the head is all - we know you are not...? I would not call a bogus Default monitor reinstalling itself a clean install, so no, not a good thing at all. How far should you go? As far as the road takes you, kinda like the length of your legs, certainly far enough to reach the ground. The really nice thing about all this is - it doesn't matter how far you take the removal of devices from the Device Mangler. Please remove them all just for kicks. It really doesn't matter, as it doesn't hurt a thing. At reboot Windows will spend some time reinstalling all that stuff and you might be right back where you are now - unless this drastic measure actually fixes the Default Monitor problem in and of itself. Which is very real possibility!!! I won't tell you to do it right now because you are probably sweating real bullets, but at least think it over some. Coincidently, the deletion of the entire ENUM key just prior to shutdown is one quick and dirty way to install Windows onto any machine by simply swapping out the booting hard drive to the new machine. At boot up, in the new machine, Windows will detect all the "new" hardware and install the correct drivers and poof you got Windows - neat method, if the legalities are a separate issue. I have done this and it works just fine. Both via the registry and the Device Mangler just to be sure both methods did pretty much the same thing - they do. I would certainly remove all instances of the Default Monitor found in the registry. Your ICM file is most likely in the Windows\INF folder now if Windows is not asking for it's location, and that's just fine - it's supposed to be there if it's not too big along with the inf file. It's just nice to know exactly where stuff like that is actually at for a possible future "clean" Windows reinstallation. Clean Install is usually in reference to a Windows installation denoting a blank hard drive prior to the actual installation as in opposition to an "over the top" reinstallation of Windows to a hard drive that already has a working or not working Windows installed on it. |

Hmm. I thought you meant you were about to delete the entire ENUM key or otherwise decimate all manner of devices listed in Device Manager-- which is a far more perilous affair! I don't want it on my head-- even if you do have two full backups. Of the two, Norton Ghost sounds to be independent of Windows. Does Roxio Go Back require a boot to Windows for it to work? (I use neither of those two.) Therefore... let it be on Lee's head, or even on Terhune's or glee's, who also have posted of such things in the past! If using Device Manager, I know you must remove the child devices, before you may remove the parents. Also, it may be advisable to set the display adapter to "Standard Display Adapter (VGA)" first, if you intend to remove that one. Finally, I've read you may expect multiple reboots for some of them to come back. And I hope you won't be requested to insert the Windows Installation CD or any other CD-- especially if that's one of the devices you've removed! Help us help you... What is your particular problem? Please supply OS, computer manufacturer, display manufacturer, statement of your particular issue, and anything else which might be related to help localize the issue. Is it VISTA or XP? Sounds like XP, but why? If VISTA, depending upon when you purchased the laptop you may be able to contact Lenovo for an install disk [may take some prodding]. As for the multiple extra monitors in XP,, the only time I had that occur was when I installed newer drivers without uninstalling the prior, leaving the system with two distinct driver versions [both providing multiple monitor support = 4 monitors-2 screens/2TV-projector outs {2 disabled/not functioning}] and a default [=5]. |

What happened with this? I have a similar problem. Was there any resolution? I have a Lenovo ThinkPad x61s. I tried to do a clean XP Pro install and ended up with 5 default monitors (none of them the correct one) in Device Manager. When I was using Vista it listed only one monitor... the right one! I didn't install extra monitors, the whole install went really smoothly. I have tried deleting in Safe Mode but they keep coming back. I figured it would be easy to reinstall Vista to see what the settings were by using the blue ThinkVantage button to install the original factory OS. Wrong! It would not work at all. Error messages saying it couldn't find the files (though the partition was left untouched by me). So I thought fine, I have the original CD's. Installed and it was XP Pro and not Vista!!! Looks like I have no way of putting Vista back on again. Anyhow, I checked in Device Manager and I still have the 5 monitors listed along with 2 video drivers (although that is perhaps okay because it can run dual monitors???) I am trying so hard to get a clean install so I can back up a perfect image. Blah, I'm sick of it all... and soooo boring to install. Can anyone tell me how to deal with the extra monitors? I'm sorry, I don't understand how this is being sent to a win98 news group. I don't understand how this website works. I will try another place. ps. to Meb: I want XP but not if I can't get devices installed correctly. I have tried everything I know to get rid of the extra monitors with no success. It was on a clean install and when I installed the video display drivers is when I ended up with 5 monitors. Previous to that there were none listed so I don't don't know how it can be a problem with installing over other drivers. Oh wait, I see where I went wrong with my posting. Sorry Everyone. I will move my questions elsewhere. I have tried installing with the oem discs from Lenovo and I have also tried reinstalling with the ThinkVantage button (disc image) and also with a clean xp pro disc. I got the same result for each installation. I would think that the OEM disc would give me a perfect install without any input on my part, but it didn't. The monitors do not show in Device Manager until I install the video adapter drivers. Then all five show. When I install the correct monitor driver by updating the driver, all the other ones remain or are reinstalled after rebooting... Even when they are uninstalled in Safe Mode. |

Your message has ended up in a Microsoft Windows 98 news group, where there are not many people who know anything about XP or Vista. You should advise Techarena that they are forwarding your messages to the wrong newsgroup. Or, perhaps you have selected the wrong Techarena forum. Better still, use a newsreader such as Outlook Express and subscribe directly to a Microsoft newsgroup related to XP installation or video issues and avoid all the problems of a web interface. You will find the MS newsgroups at msnews.microsoft.com. Here are the potential Microsoft Support Forums that might be of present interest to you: news://msnews.microsoft.com/microsof...indowsxp.video news://msnews.microsoft.com/microsof...owsxp.hardware news://msnews.microsoft.com/microsof...dowsxp.general As for the display I mentioned: XP had already installed a set of default/generic [Microsoft supplied] drivers (which did not appear in Add/Remove ;}). When I installed the new manufacturer's drivers, instead of removing and replacing the default, the installer created a second distinct set of drivers. Upon reboot, both the original defaults and the new manufacturer driver were then both shown as installed. I should note this was shortly after XP came out [and I was still learning about the OS, hence I made all the usual errors], and drivers were still being modified [it was an integrated {IGP} ATI IIRC, might have been a NVidia though]. Did you perhaps use the manufacturer's driver disk? Instead of installing the drivers {running the setup file}, did you try *updating* the listed driver already installed? (check AFTER XP has fully set itself up and you have rebooted at least twice) Don't forget XP has Restore Points.... |
