Auto Detection Of Plugged / Unplugged Monitor No Longer Works
Jul 2, 2012
When I plug in or unplug my external display to my laptop, my display options no longer automatically reconfigure as they used to do. Now if I unplug the monitor, Windows acts as if it's still there, and windows that were on the monitor stay offscreen (as does the cursor, if that's where it was). I can manually move the cursor back, right-click load graphics properties and make changes OR do an F-key combo to move everything back on the laptop screen OR program a hotkey but these are all pretty annoying for one reason or another. Unfortunately this must have started happening sometime in the last two weeks--at the same time as I made a load of major computer changes.
However this did NOT include a graphics driver change (my graphics driver is current). At this point I feel it could be anything, but I'm wondering if it could be a recent BIOS update I did that HP recommended. By way of troubleshooting I did run Windows in safe mode with ONLY the "ATI Catalyst" and "AMD External Events utility" running on top of the basic services, in case a newly installed service was stealing hotplugging messages, but that didn't do anything. I've also gone exhaustively through my graphics driver settings to make sure everything there looks correct.

I have a wireless logitech headphone. The speakers work ok for the most part, but, the mic does not always work unless I manually configure it for the headphone. And after I get done talking it very often reverts back to the builtin mic. a blog but they saw it on dv9000 (I think). There was a solution given for that driver but not for my dv2700.

I have just recently built a new computer and am trying to use my older vga monitor with it. The monitor displayed fine while installing the os but after it finished the monitor goes right into sleep mode. I updated all my drivers for the onboard video and my video card and have switched between the two in my bios trying to make it work. So far the monitor displays up to the loading windows screen then goes straight into sleep mode. The most annoying thing is that the monitor works fine as a secondary monitor, just not a primary.

I have a Sceptre X20WG Naga 20.1" monitor on a DVI connection with my EVGA GTX460 card. I was using it yesterday while studying for finals and decided to hook up my 37" Westinghouse TV via VGA connection, using a VGA-to-DVI converter to plug into the graphics card, as the card only has dual-DVI and mini-HDMI outputs. It was working grand as a second screen, no issue at all. Now, today, I turned on my computer and my Sceptre Monitor wasn't outputting any images at all, it just said no signal detected and then went to sleep, though my computer was still on.
So I turned on the TV out of curiosity and found that the TV was now the main screen, still with the VGA connection, and I hadn't unplugged anything since yesterday. So I logged in and right-clicked on the desktop, went to screen resolution, and here it says that the TV is the only screen detected, even after hitting detect. So I unplugged the VGA from to TV and plugged it into the Sceptre Monitor. Turned on the computer and the monitor worked like a charm on the VGA cable. I also plugged the DVI cable that I was using for the monitor into the TV and that worked like a champ too.
The only reason this is bugging me is because I won't always be using the TV as a main display because it's kinda of a pain to sit close to a screen that big. So I am currently on this forum while my monitor is using the VGA connection. It also seems to vary from which DVI port I use on the videocard because if I plug the VGA cable with converter into the 2nd port, there is no video output, but if it's in the first port, works great. I'm going to try just the DVI cable to the TV on each card port to see what the deal is there.
So basically:
The cable isn't the problem.
The VGA needs to be in the 1st DVI port on the card to work.
The DVI doesn't work at all when hooked up to the monitor.
What I want is to be able to use DVI on the monitor and VGA on the TV.
Specs:
Intel Core 2 Quad Kentsfield Q6600 2.4GHz @3.0GHz
8Gb Kingston ValuRam DDR3-1333
Asus P5G41T-M LX Mobo
EVGA GTX460(2x Dual link DVI and 1x mini HDMI)
Windows 7 Professional x64

So my grandpa got a new laptop for his birthday a while ago... Strong laptop, nice hardware. Can't remember the name or model though...Anyway, so he runs Windows 7, and he told me that every time when he pluggs out the charging cable, the computer shuts down. But when the cable is plugged the computer runs just okay and the battery is full.

I have a SONY vaio vpcea16fg , and a windows 7 professional installed on it. I want to disable windows from auto detecting my built in usb 2.0 camera. I have disabled UPNP and SSDP services, but it doesn't work. I mean when I restart my machine in detects usb camera and install it again!
I want to disable my webcam auto detection, because there is a hardware problem with my built-in webcam and causes a blue screen error. When I move my laptop's lid, windows detect the camera and try to install it automatically, but after two or three times of detection a blue screen is occurred.

I want to disable all auto play, auto monitor detection, auto audio detection, ect. i want to tell windows that i have X amount of monitors and to always display on them, that i have 7.2 surround and to ALWAYS send audio out via HDMI. if i unplug the hdmi or a monitor i dont want windows to do jack i just want it to sit there and play/display to a component that is not plugged in. all this auto detection crap does is waste my time and cause issues with my day to day computing.

Every day or two, Windows 7 is REVERSE dimming on me and I can only fix it with a reboot.What I mean is, suddenly when the AC Adapter is PLUGGED IN, the screen will be DIM (Even though control panel shows it as max brightness on the slider). But then once I UNPLUG the adapter, the screen is bright like its supposed to be..For the life of me I can't figure it out, but it's driving me to the point of insanity because I keep having to reboot so often.

I installed 7 with two monitors hooked up and turned on and it detected both of them just fine. But after the install when I boot to windows if both monitors aren't "on" when I boot it won't detect the second monitor when I turn it on. I have to boot with both monitors on for it to detect both of them.
I just want to see if anyone else has experienced this same problem?

i have connected my monitors via displayport to my computer. displayport is very nice, but it has one feature that is - in combination with windows vista/7 - very bad. displayport specification says that if a device (Monitor) will be turned off (standby) it will not be visible to the computer anymore. that is very annoying because windows has a routine which permanently checks if all monitors are still connected. if one monitor will be physicly disconnected, then windows will reorganize the desktop (all content that was on the disconnected screen will be moved to the others). if the monitor will be turned on again windows will move the windows back to the place where it has been before, but often it does not work correctly.

I have a three monitor set up. Whenever I open up a browser, either internet explorer or google chrome on monitors 2 and 3, after a few seconds it automatically drags my browser into my main monitor(monitor 1, where my start button and status bar is located)

I recently updated my nVidia drivers to the latest and also my SiSandra Lite software (for quick access to accurate specs of my PC). After updating SiSandra Lite, I looked at the GPU section. As usual it loaded the primary monitor first where everything was fine. I then changed to look at my secondary and my primary monitor turned off and my desktop was shifted to my second.Now when I boot my computer, my primary comes on, but after the pre and post bios. Only when Grub comes on does something appear on my primary monitor, but it's very low resolution (compared to what it used to be). The windows 7 loading bar appears on my primary but before the logo can appear and glow, it swaps to my secondary monitor where it stays.
Windows 7 cannot detect my primary monitor trying both screen resolution detection and it's missing from the devices menu. Really confused about this whole business.I realise this may have been posted as a problem before. I did find little snippets of information about it but nothing sufficient.

I just got this new computer, running 64-bit Windows 7 Home Premium. Everything was working fine at first, but then it automatically updated some things. Now, Flash doesn't work online anymore, in any browser. The content starts to load, then the browser freezes, and I have to force quit it.
I have the most recent version of Flash Player, and I can still play .swf files I make myself, so I don't know what to do anymore.
I'm fairly sure that this isn't an isolated problem, as a friend of mine is experiencing the same thing.
In a possibly related problem, .avi and other video files on my hard drive no longer play, nor do music files.
I doubt my specs are needed, since this is almost certainly a software problem, but I'm running on a Dell Studio, with a 2GHz dual core processor and with 4Gb of RAM.

We used to use ZetaFax, I'm told. I'm new to the company. We no longer use ZetaFax. Since bringing in Windows Vista Business and Windows 7 Pro computers, and Windows 2008 Server, we now use Windows Fax and Scan.We use Fax Server on the server with quad port RocketModems installed.Now, here's the problem.Some of our employees are having problems using Windows Fax and Scan. The way they use faxing is by finding the file (usually an Adobe Acrobat pdf), open it and then go to the Fax printer.This then auto faxes the document using Windows Fax and Scan.For most of our employees, this works fine.But, suddenly for some it does not work. When I visit the ones who can't fax, I open Windows Fax and Scan and try to launch it. It does not launch. On some of the computers, the user gets a message that the format must be tif. For others, they get a message saying that they can not access to the document folder.I'd like to remove Windows Fax and Scan on these computers and try to reinstall it and see what happens. How can I do that?

So I opened up my tower to do some dusting and I accidentally dropped the tower door and the wires that power the tower door fan was ripped off. There was a red and black wire that has these weird looking prongs on them. I first did not know where they went... So I just looked at the 4 pin whole plugs and started to stick these two in these plugs to test... First few times I did this; the pc restarted and there was a spark....(could this be y my background no longer works?) Then I found two holes out of the four pinned plugs that powered my fan.. Hurray I thought cause the fan was powered, the blue light was on and I was happy for that moment. Then I realized my background was just a blank color.. So I right clicked/personalize/desktop background/ set up the photos I saved/hit save changes. and nothing. no background.

Windows 7 Ultimate, 32 bit. Not on a domain. After I installed SP1, "Switch User" disappeared as an option. "Hide entry points for Fast User Switching" in GP Editor is set to Not Configured.
I also checked the Application Information service as Andre suggested, and it was not running. I started it, set it to automatic startup, and rebooted. Still no joy.
I have uninstalled SP1, and I now have the option to switch users as I did before installing SP1.
I'd prefer to keep my system updated, but for this system anyway, the ability to switch users as opposed to logging off is more important.

I installed a hard drive and upon installing drivers for my nvidia gtx 460, it just gave me a black screen once I got to the login screen. Went back in to safe mode and got older drivers, that didn't work either. I have tried 4 versions of the older drivers and it all goes exactly the same. Clean install of windows 7 Home Premium 64. Or do I just need to get a new motherboard/videocard? Also I have a dual monitor setup and the second monitor doesn't get a signal.

We have a script that installs an application on a user's box. It can run on XP, Vista, Win 7.... So it uses the ver command and find to figure out what the os is. It used to run on my win 7 box. It no longer does. The find command now gets an error. I tried substituting findstr and it returns a good completion code regardless! The grep command works great but most machines don't have grep so that is not an option to use. I would just like to figure out why find doesn't work. The date for find.exe in the System32 folder says 7/13/2009. Is there something I can do to restore find? Listed below is the the command & output that helps determine the OS version using find/findstr/grep

My A200 has been upgraded to 4GB RAM, and Win7, worked fine for a while, then started randomly freezing with weird screen stuff (video not displaying properly). Power off only worked. Much frustration and removal of progs later, tried on safe mode - works fine. Safe mode with networking - works fine. Can plug it in (surefire way to get it to fault normally) and in safe mode it works fine, in normal mode, immediate fault.
Thought perhaps a horrible malware, did clean install from disc of win7, no change (except now, coz I deleted all the Toshiba drivers, the dvd drive is noisly lol). Can't load progs to run the damned thing properly because it won't run in normal mode, only safe mode. Tried formatting the hdd, but it won't let me (partitions) which I thought were reformatted during a clean install anyway?
Haven't tried changing the charger yet, because it works fine in safe mode, so I thought probably a software issue? Have tried minimal or "clean" normal boots, freezes immediately.

I installed Windows 7 Ultimate x64 and now my built in webcam no longer works. I have a Toshiba Satellite L510-016. I am unsure of the webcam model itself as no information seems to pop up for it anywhere on my computer. I have tried installing drivers with no success.

i noticed that my PC had been using a lot of the SSD for information i felt should be saved on the HD. i read some forms and someone said that the C:USERS folder can simply be dragged to the HD so that everything is saved there. so i copied it onto my other HD and renamed it USERS2. unfortunately i noticed that this didnt and doesnt work and for some reason the USERS folder on my SSD has gotten renamed to USERS2 as well and the Catalyst Control Center application no longer works... i dont know how to fix it and im afraid that i might dig myself further into this mess.

I have a Lenovo H405-7223-1GU that I bought in June 2011. Yesterday I bought a Philips 32" HDTV 720p 60Hz. My PC won't recognize my TV at a monitor via HDMI cable. The ports on the TV and the cable is fine because I can connect my DVD player with no issues. Most help is saying to right click desktop, click "screen resolution"and then just tell the PC it's ok to send info over HDMI. That would be fine but I can't have my monitor and HDMI plugged in at the same time. As soon as the HDMI is plugged in my monitor (VGA) goes blank then comes back on with only the background image showing. No start button, no icons, no toolbar

a few days ago on boot up my laptop restarted and then attempted windows repair. came back to life. tonight while viewing Internet my screen went black. i had to hold the power button down to restart. i chose start windows normally. when attempting to load windows i got a blue screen saying "attemp to restart display driver has timed out". after a few attempts i have managed to get it into safe mode and deleted the nvidia graphics driver. restarted and all was fine (low resolution). i installed the graphix driver again an it happened again. is my graphics card broke?
alienware m7700 d900k
amd athlon 64 x2 4600+
geforce 6800 ultra
windows 7 64
2gig ram
the nvidia driver does not detect my graphix card so i have to add it in the setup information file. but i have had no problems for about nine month since i bought this laptop second hand.
i joined this site for another problem a few days ago. slow speeds and constant hdd access but had a good clean out and was going to see how it went. then this happened. i do not think they are related.

So I just upgraded from a GTX 560 TI to a GTX 670 and now my computer can't detect my second monitor. My main monitor is plugged in via DVI while my second computer is plugged in via HDMI. I've been on nvidia control panel and tried finding my second monitor there on the "multiple monitors" section, no second monitor there either.
