Will Not Recognize My 2nd Monitor

Dec 16, 2009

I am running Windows 7 Ultimate on a Macbook Pro, and I would like to use the laptop screen as well as my ASUS 23" lcd monitor. When I open the display > screen resolution window, it shows that I have only one display, and gives me no options for multiple displays. The same image is displayed on both screens. My 2nd monitor is hooked up through DVI, and worked just fine with Windows XP. Does anyone know what my problem might be?

[GRAPHICS] Monitor Suddenly Will Not Recognize Computer

Aug 21, 2012

So I went on a three day trip. When I got home, I turned on my computer. The cooling unit made an unusual noise, and all of a sudden the monitor turned off, as well as the computer. Now, whenever I turn on the computer, it works perfectly fine (The cooling unit noise is gone also) but the monitor just goes to the ASUS boot logo and tells me VGA no signal. Even that only happens sometimes, it will mostly just remain in sleep mode. Things I have done:

- Tried with a different monitor
- Tried with DVI cable

I wish I could tell you my graphics card but I just don't remember.

Laptop / Video Card Won't Recognize Second Monitor

Aug 12, 2011

I have had a dual monitor setup with my laptop(Inspiron 1545 with GM45 Intel Card) extending to a regular LCD screen. It worked for two months and until recently has stopped working.I have uninstalled, reinstalled, uninstalled, reinstalled the newest drivers, changed the cables(power supply and VGA), system restored back a month to when it was working, and changed the power outlet.This originally worked flawlessly and now the laptop is not recognizing any device I attach via the VGA output. I have plugged the laptop into another monitor with no avail as well. I find it hard to believe that this would stop working one day with no notice or any problems. I have also tried attaching a projector that had worked for over a year with the laptop and have gotten nothing.

I receive a black screen as if to say this something being outputted, but nothing is displayed. Both windows screen resolution and the intel GUI both do not recognize another device. [code]

Windows 7 Not Recognizing Second Monitor For Dual Monitor?

Jul 4, 2011

This computer is running an ATI Radeon HD 2400 Pro. It does support dual monitors...(I've had dual monitors active on this card before, but never on Windows 7.) But since installing windows 7, I can't even get it to detect the second monitor. I want to run the setup with the CRT as the primary monitor and the HD as the secondary.

Dual Monitor Setup - Fullscreen Goes On Wrong Monitor

Aug 14, 2012

I am running a dual monitor setup with my TV hooked up via HDMI to my laptop.

Everything was working fine before, I always had the laptop as my main display yet I could play a video or a game fullscreen on the TV.

Since a couple of days, as soon as I put something in fullscreen, it immediately goes on my laptop, regardless if it's open on my TV or my laptop. I don't remember changing/installing anything that could've changed that...

I checked a bit in the AMD vision software and the Windows control pannel but I can't seem to solve my problem without switching my TV as the main display. I also made a quick search on google as well as here but the problems were mainly with Flash, which isn't in cause here.

Here are my system specs:

Toshiba Satellite L75D
Windows 7 home premium 64-bit
AMD Radeon 6520G

Dual Monitor Issue, Secondary Monitor Is Undetectable

Jan 6, 2010

I have just did a clean install of Windows 7 ultimate from XP and I am unable to get my dual monitors to work like they did in XP.

I have a DVI Radeon graphics card plugged into the agp slot, and a Nvidia geforce vga adapter plugged into a pci slot of my dell optiplex 755. When I am in the screen resolution settings the second monitor cannot be detected.

In bios I have 2 options under primary video adapter and they are auto, and onboard card. When set to auto the Nvidia card gets a signal but the Radeon does not. There are no conflicts in the device manager, and all of the drivers are up to date.

When I change the bios option to onboard card the Radeon adapter gets a signal but the other monitor cannot be detected and in device manager there is a yellow exclamation mark next to Standard VGA adapter and a code 10 error that states the device could not be started.

I have powered down, and unplugged every cable, I also tried to use the integrated VGA adapter to the Intel G31/G33/Q33/Q35 Graphics Controller but the computer will not even boot. I get

"System Halted

Attention Unsupported Video Configuration Detected"

I have two monitors, both work fine as standalone but Windows will not detect either as a secondary.

Please help me someone, I am so used to having my helpdesk email open in one monitor and all of my other work in the other monitor.

Primary Monitor Switches To Secondary Monitor?

Oct 21, 2010

I recently had an older HP Pavilion Media Center m7760n Desktop PC rebuilt. The old power supply fried the motherboard so I need to get a new power supply and motherboard. Here are my current specs.

Mainboard : Asus P5QPL-VM EPU
Chipset : Intel G41
Processor : Intel Core 2 Duo E6420 @ 2133 MHz
Physical Memory : 2048 MB (2 x 1024 DDR2-SDRAM )
Video Card : Intel(R) G41 Express Chipset (Microsoft Corporation - WDDM 1.1)
Hard Disk : WDC (1000 GB)

[code]....

As you can see from above, the "video card" is actually integrated into the motherboard.The computer works perfectly except for one major problem. I have 2 monitors, one is 22" with 1680 x 1050 resolution and the other is a 15" monitor with 1024 x 768 resolution. At the back of my computer I have a VGA port and a DVI port. The 15" is connected to the VGA port and the 22" is connected to the DVI port.When first starting the computer, the 15" monitor was recognized as the primary monitor while the 22" was recognized as the secondary monitor. No problem. I simply went to the display settings and set the 22" to be the primary monitor and the 15" to be the secondary monitor. Unfortunately, this setting seems to reset as soon as I reboot the computer. The 15" is always set as the primary monitor on start up, forcing me to set the proper settings all over again. What's worse is that even after I have set the proper settings, they sometimes revert back when using Media Center or other programs. Worse yet, sometimes the monitors both go completely black ... as if the monitor settings were about to switch but got locked up some how.I'm assuming that perhaps the on board video has a primary port (VGA) and a secondary port (DVI) but even still, shouldn't Windows 7 be able to over-ride this and save these settings so that the monitor settings remain the same during startup and regular usage?

Dual Monitor Desktops In One Monitor?

Feb 3, 2011

I'm using a television (32p) as a second monitor in extended mode so that I can watch a movie in the TV and play a game in the monitor (this was my main goal). Monitor and TV lays in two different ambients, both connected to the same pc, one by normal VGA cable and the other by HDMI. I managed to differentiate the audio output so that VLC player sends it's audio to the HDMI (so that only the TV plays it) and the rest of system sounds, media players and games outputs to the speakers (basically only the VLC audio is directed to another output device). I reached my goal so that I can watch a movie fullscreen in the TV and play a game in the monitor fullscreen too without any interference from one another (nor audio or video).

The thing is, because I have the TV in another ambient I can't actually see what's going on in it, as I just "throw" the VLC window to the TV from my main monitor. And here's the question: There's a way to see the TV's desktop in my monitor? Without having to set it as main monitor so to not really switch between desktops.. The perfect thing would be if I could see the TV's desktop in a window like in remote desktops applications.

Windows 7 Won't Recognize Sim Card

Apr 27, 2012

On my PC there is a card reader connected. It shows up as 4 different drives when I look at "My Computer" and elsewhere. One of the slots in the reader is for sim cards. When a sim card is inserted a Windows sound is heard and the "Installing Device Driver" window shows up but then another window stating the installation was not successful. Any further action from within windows does not solve the problem. I tried an external card reader connected via USB and the same negative results. this was tried with 3 different sim cards.

Windows 7 Does Not Recognize Administrator

Jan 24, 2011

I did a quick search on this site on "Administrator not reconized" and found the only threads mentioning this problem have both been closed. My problem is that in trying to download the entire HP driver/software disc for my hp printer psc 1350 series, I was not able to download the entire software, because I did not have Administrator's rights, etc, even though I was the only Administrator (and sole user of this computer at that time). I did some research online and followed one suggestion that I followed, which was to change the setting by going to Start, typing 'cmd' in search field, and typing in 'net user administrator /active:yes.' This created another "Administrator" user, which I am now finding quite useless, since many of my programs have already been downloaded on my first "Administrator" status. I need to know how to remove the last one I created (Administrator), if possible. As it stands right now, the one I had before is the only one with the option to delete. (Ugh!) In any case, even having the second Administrator user status, will not allow me to download the above mentioned software completely. So, I went full circle with the same problem, with no solution.

1) Remove the second Administrator user, and 2) how to get Windows 7 to allow me to download the above mentioned. BTW, I have already tried right-clicking the disc drive (setup file) and clicked "Run as Administrator" - all to no avail. Nothing seems to work.

Windows Won't Recognize EasyCAP

Apr 5, 2012

I've just got a brand new EasyCAP capture card and my computer won't recognise it. In device manager it appears as SM-USV 007 in "Other Devices", and none of the tutorials i've been looking at say that. They all recognise EasyCAP as a capture card. My other problem is that my laptop won't read the installation disc for some reason. I don't know if it's the solution to my problem or it just contains drivers and the screen capture program. I have downloaded the Windows 7 x64 drivers and installed them but it fails to find them for the device.

Windows 7 Won't Recognize Headphones

May 28, 2012

I wondering if anyone could help me, when I'm playing a game on the pc I would like the sound to come from the speakers but use the front jack to plug in my headset and talk to friends on skype.My problem is the sound from my game comes through my headset as well and it's very annoying! Also if someone else is on the pc and i'm on a skype call I have to ask them to mute the sound on the pc.
I have Realtek Hd Audio Manager installed and it recognizes the headset when I plug it in but in control panel under sound it doesn't,it thinks my headset is speakers.I've searched and searched for a solution, apparently older versions of Realtek had better options for controlling jacks,the one I have even though it's all updated is very basic with no options to change any settings to do with jacks.

Force Windows 7 To Recognize DVD-RW?

Aug 25, 2011

I disassembled my computer, carried it in my luggage and reassembled it. The only thing changed is the case. Since reassembling it, Windows (7 ultimate 64-bit) will not recognize either of my 2 DVD-RW's. At boot, my bios offers them as boot options, and with the Win7 disk in the one, it will boot from it if selected. However, once within the Win7 environment...nothing. Not even any yellow exclamation marks in device driver. I have tried to force installation, tried installing a legacy device, everything I can think of. how I can force Win7 to search for and find my DVD-RW's?
