Win7 Will Not Detect Second Monitor


I have a pc running windows 7 professional and windows vista ultimate with a dual boot setup. I have two screens pluged into an nvidia gts 8800 video card. The first screen is an hp 22" lcd which is plugged directly into one of the two dvi outputs on the video card. The second screen is a sharp 52", 1080p hdtv which is plugged into the second dvi port on the video card via an hdmi cable plugged into a hdmi to dvi adapter.

Both monitors work perfectly when i boot to windows vista but when i boot to windows 7 the 52" screen is not recognized at all. If i switch the cords plugged into the video card the 52" will work and the 22" will not be detected.

Win7 Does Not Detect External Monitor

I have just upgraded to win7 home premium 32 on a sony vaio laptop. Previously i was running vista business. I was happily using an lg1512s monitor plugged through the vaio docking station.
Post the win 7 install, my laptop does not recognize the external monitor. I have gone on to the control panel all control panel items-display-screen resolution and the multiple screen dialogue does not appear.
 
I have with no success:

ˇ Clicked detect in the control panelall control panel itemsdisplayscreen resolution
ˇ Clicked the f7 monitor on/off button.
ˇ Plugged the monitor directly into the vaio (i.e. Not through the docking station)
ˇ Used windows-x and tried to use the mobility centre to connect the external monitor.

Meanwhile i have plugged the monitor into another laptop i use that is running vista home and the monitor lights up so i know the monitor and the cables are ok. The problem is that win7 is not seeing the external monitor. Any ideas?

Win 7 Fails To Detect 2nd Monitor On Boot

Clean install of win7 with ati radeon hd4550 pci express graphics card. Running a mitsubishi diamond plus 100e monitor and a sony multiscan 500ps monitor, both off the 4550 card. On boot, the primary (mitsubishi) monitor is detected and the second (sony) monitor is not. I can open the control panel for screen resolution and see both monitors correctly identified. If i select extend these displays, windows re-labels the sony monitor as generic pnp and the sony monitor then activates and works properly.

As soon as i shut down the computer and reboot, the sony monitor is again undetected and i have to go through the whole process again. I have deleted all ati drivers and reinstalled current catalyst drivers (8. 732, 5/26/2010), as well as current motherboard drivers. (Motherboard is gigabyte ma790gp-ds4h). Integrated graphics card on motherboard is currently disabled, although this made no difference to the problem.

Dual Monitor Problem - 2nd Monitor Detected Black

Ok, so i have a dell that was running vista and two monitors. When i upgraded to windows 7 pro i ran into the infamous black screen problem and fixed it. However, i only fixed my main monitor. When i open the display window, both of my monitors are detected but my secondary monitor shows a black screen and the monitor itself says there is no signal detected from my pc.

The strange thing is my pc thinks its working (i can drag a window from my working monitor towards the black one and it moves out of my working monitor into the black screen). I currently have both of them plugged in using a dvi to vga splitter and i have also updated the drivers by clicking the "update driver" button in the monitor properties window. Please help if you can!

Cannot Move Windows From One Monitor To Other - Dual Monitor Setup

I have two monitors of the same resolution connected to an ati radeon hd 4300/4500 video card. In windows 7 extended mode i see a full working desktop on one monitor, but only the background picture on the other - the four-square flag motif again a blue background with wispy lines, butterfly etc.

No taskbar, icons or anything else. On one occasion briefly the mouse cursor appeared on it instead of on the full desktop image. If i try to drag a window on to the second monitor it won't go there. The settings are landscape with two mointors "1" and "2". I have two images but how can i use the second one?

Cannot Detect Dvd/cd Drive

My averatec 4200 laptop was just upgraded to windows 7. The dvd/cd drive worked fine when i installed windows 7, but for some reason it is no longer visible, anywhere.

Device manager - nothing
My computer - nothing
Hardware & sound troubleshooter - no device detected

I have tried everything i can think of. The dvd player hasn't been removed physically and reinstalled. Also, when i put in a dvd the player spins, but nothing is detected.

Cannot Detect Wireless Connection

I have a wireless modem set up and other laptops in my house can get a signal but my own personal laptop cannot. The wireless network list on my computer shows that the network is detected and that i am connected. Despite this, the signal comes in and out and tends to be very weak. The signal on the bottom right shows full bars so the signal is supposedly very good but somehow i cannot get on the internet. I have tried multiple websites and the message that internet explorer cannot open the web page comes up.

Applications Cannot Detect Dvd Drive

I am having trouble with my cdvd burner, as no applications on my computer recognize the drive at all. The hardware was working fine and was displayed under a list of burners in applications like cyberlink dvd, nero, windows iso burner, windows media player; now it is not displayed at all. I constantly get error messages that "no burners were detected" or to "connect a burner and restart the [windows media] player. " The drive does however appear in windows explorer and i am able to play dvd's from it (although i believe these are stored in a temporary cache).

I have already attempted to reinstall the driver from "device manager dvd/cd-rom drives hp dvd rw ad-7581s ata device" but this had failed. I have also run the online "playing and burning cds dvds and bds" troubleshooted from microsoft; it finds no problems, probably since it did not actually burn any data to test it. I've also downloaded the mats_run. Dvd.exe which supposedly fixes the problem automatically, this just downloaded massive amounts of data and went to the above troubleshooter. I am not able to burn dvds and no applications even detect i can.

Macbook Does Not Detect Wireless Network

Window 7 installed on macbook - does not detect any wireless network/connection at all only on windows os system side. I have installed windows 7 on my new macbook, so my macbook operate both on apple macos and windows os. However, my windows os side does not detect any wireless network at all. When i switch back to apple os, there is no problem connecting to the internet and there is no connection problem at all.

But for some reason, my windows 7 does not detect or show any available wireless network. I use linksys wrt-110, and i don't think it is my router problem because it works perfectly on apple macos system. Does anybody have any solution? I am not very tech-savvy, i.e. , I need step-by-step explanation as to how to tackle this.

System Wont Detect Cds

After performing a clean install of windows 7 pro my computer wont detect music cds. It will play movies with its corresponding audio. But it wont play regular music cds originals, burned or from any file extension of music cds it wont just detect that the cd is loaded in the cd rom tray.

I already tried  windows trouble shouting and nothing. Checked file extension association and everything appears to be in order. I also ran drm. Also perform cd, dvd region check. Lastly i also perform a system check from the windows command prompt and found nothing either.

Anybody have any other ideas?

Cannot Detect 2nd Hdmi Tv Display

I had a vga display as my primary display and a hdtv display via a hdmi cable as a second display hooked up to my computer. This worked fine until a month ago. When at first the picture showed only a zoomed in top left hand corner of the screen on my hdtv with all psychedelic colours the first thing i tried was a roll back of the updates but this had no effect, as dis changing the cable. Then when i changed the graphics card windows 7 stopped being able to 'detect' my second display with either card.

Any ideas or solutions would be most helpful?

Win 7 Does Not Detect Sdhc Memory Card

Just got a new hp elitebook 6930p computer with integrated sd card reader with ricoh r/rl/5c476(ii) card bus controller. I have used my 4gb verbatim sdhc memory cards successfully in my old xp machine (hp nc 4-thousand something) with a sdhc update from microsoft.

The problem is that windows 7 does not detect my sdhc card when inserted. I suspected something similar what i needed to do in xp, but i am unable to find new drivers or similar sw patches.

I tried to uninstall smart card reader from windows device manager along with all usb controllers (as instructed in an article in this forum), then rebooting (thus updating usb stack), but without luck.

I also got usbdeview sw to see what is happening. It seems that that device (usb 2. 0 flash disk usb device) is not connected, drive letter seems fine (g:, no conflicts), device is enabled (and it does not help if i disable and then enable it again). What i should do to have windows 7 support sdhc cards?

Language Auto Detect When Installing Programs

I have a windows 7 - 64-bit home premium edition on a new computer (hp). Language and regional settings are set for danish and denmark. I have installed the chrome browser, gimp and vlc media player. The installation completed without problems except for one thing: menus etc. Are in swedish! Why is that?
 
According to gimp help files, that program uses auto detect to figure out which language to use but get it wrong! What is going on? It seems to me, that there must be an error in the handling of language settings in windows 7. Why else would three programs in a row get their settings wrong?
 
Any ideas?

Win 7 Does Not Detect Dual Core, But Bios Does

Windows 7 pro does not detect dual core, but bios and intel processor id tool does; have tried everything. Have a e6600 dual core, evga 680i board, 4 gb ddr26400, gtx260, 7 pro upgraded from vista. I have looked all over and tried almost everything. Bios detects dual core as it allows me to enable or disable the second one, and intel proc id tool detects 2 cores. However, windows 7, and any other programs like cpuz and core temp report one core. Under device manager only one core is listed under processors, and under computer it says acpi x64 pc or something instead of acpi multiprocessor.

Msconfig only shows one core to be enabled/disabled. Have done repair install, full install, reformat install and still only one core shows. Tried easybcd with core=0 to try and reset, and nothing. Bios is up to date (p33), reset bios settings and even escd reset. This all started after power cut out randomly. At first, windows would not boot, but did mbr repair using a 7 home disc and it booted. Few min later comp felt sluggish so looked at cpu usage and task manager and found out about only one core detected. One graph/cpu is already selected as it is the only option.

Win7 Doesn't Detect Usb Mouse

I have a simple problem that i can't seem to fix. I have been using the same usb mouse for about a year now, and recently windows has stopped detecting it on startup. It is easy to fix, i simply unplug and replug it back in and windows recognizes it and the mouse works fine. But for some reason windows has stopped detecting it on startup.

I have tried different usb ports, i have tried unplugging all other usb devices and leaving just the mouse, and i have updated my drivers. It detects my usb keyboard and external hard drive every time, but windows has stopped detecting my mouse on startup. Suggestions?

Win 7 Wont Detect Ati Radeon Xpress 200 Graphics Card

Yes i have reinstalled the graphics card do not suggest it. Graphics card is ati radeon xpress 200 series. I know its old shut up. Its driver is ati2dvag.dll. I have it installed on my computer in system32, and in a folder i created, when i go into device manager and try to manually select the driver its not listed. It is inside the folder but it wont let me select it. Why?

Why is windows 7 not detecting my graphics card and using "standard vga adapter" with the driver vga.dll. Why? I have the driver it wont let me select. And the graphics card is installed. What do i do so it recognizes the card, uses the driver and doesn't irritate me anymore?

Dual Psx Usb Adapter Won't Detect Ps2 Controller

I just upgraded to windows 7 home premium from using windows xp sp3. I was just using a plug and play psx-usb adapter and a playstation 2 controller to play games such as pro evo. Now on xp i just had to plug it in and it worked fine, the same was true of windows 7 to a point, i plugged it in, the system recognized it and automatically installed it (it shows up in the devices and printers tab as a dual psx adapter) however it doesn't seem to recognize the controller when its plugged in. I've tried the solutions listed here http://reabo.co.uk/_tutorials/usbadaptervista.aspx but they don't seem to have made any difference. Any ideas?

Monitor Resolution

I have purchased a legitimate windows 7 copy. No matter how i install it it wrecks my monitor resolution. This is not a cheap old monitor, it's a fairly new one. Right now i use again vista and everything seems normal. But when i install windows 7 the maximum resolution it gives me is 640x480. It's really annoying.

Monitor Will Just Go Blank

I have an issue where my monitor will just go blank. The computer is running but no display. My first thought was that this is a display adapter/video driver issue but i not longer think so. Let me explain. My set up is a hp m9040n running windows 7 ultimate x64. I have a nvidia 9600 gso card that is less than 6 months old and use a samsung syncmaster t240 monitor.

This first started happening about one month ago right after i upgraded my video card driver to the latest version. I would be away from the computer for awhile and when i came back no amount of mouse shaking would bring the screen on. At that point a hard shut down and boot up would bring things back.

Thursday it got worse. Hard shut downs would not bring anything back but i would see the bios startup screen so obviously the monitor and display adapter has some output. I started in safe-mode and installed that latest driver from the nvidia website. No difference, in fact it appears to be the same driver that windows update put out.

My next step was to roll back my driver to the one that came with my video card. This kind of works. There are new symptoms now. Now what happens is that after working for awhile i would hear the usual kind of insert/disconnect sound (like plugging in a usb device) and then the screen resolution would change from 1920x1200 to 1024x768. For some reason the monitor according to the screen resolution control would go from my monitor to a generic. If i click on the detect button, the screen will blank out and once again i have to do a hard shut down. The hard shut down followed by a boot in safe mode and and reboot restores things to normal.

Dual Monitor

Is there any option available with using dual monitor in a "stretched" view instead of extended? What i'm trying to do is run 1 application over my 2 monitors in full screen mode. So far i haven't found anything that would make this possible. I can extend and i can enlarge a window over 2 monitors but i can't really use a resolution of ~3200 * 1050 for example. This was possible under xp but neither vista or windows 7 i can get this to work.

I've tried searching the forums but alas i have not found an answer for this. If someone can find a topic already covering this sorry for double posting. But mostly i found extending and not really stretching it over 2 screens.
