Windows 10 doesn't detect my second monitor

Q: Windows 10 doesn't detect my second monitor

I just upgraded from Windows 7 to Windows 10 and now my computer only detects one display rather than two. I have a Dell desktop computer and two Dell monitors. Using Windows 7 both monitors were being detected/used. Can anyone tell me how to correct. (I'm not very technically experienced, but can follow basic instructions.)

The second display shows a black screen with the message "Cannot Display This Video Mode".

Preferred Solution: Windows 10 doesn't detect my second monitor

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Windows 10 doesn't detect my second monitor

right click on desktop for "display settings" - pick the monitor that shows up that message -> click it to activate -> switch correct video mode for it. its prolly too high resolution issue.

also WIN+P -combination gives you chance to use "extended desktop" which you should use to configure the resolutions

Hi guys so i have 2 computers with the same problem, the 2nd is an old comp, so I'm not too bothered about.

I noticed my computer was getting a little noisey so i thought i'd clean all the dust out of it.
1st comp
i took the CPU and graphics card off to blow the dust out, also i blew air into the PSU fan.

The computer boots up, sounds perfect, but about 10 minutes uptime it will still be powered but my monitor just goes into standby, i tried with my TV too and the same issue.

2nd comp
I hadn't used for about 1 year, i tried hooking up to monitor and it just doesn't respond, i've tried with another monitor too and still the same, also tried using a different VGA cable. monitor remains standby, But unlike my other computer this one doesn't even display for 10 minutes!

Any ideas on what can be causing this? :suspiciou

What do you mean you took the CPU off? Do you mean the heatsink? The heatsink fan? If you removed the heatsink from the CPU, did you clean off the old thermal compound and apply fresh compound? If not, the CPU is overheating.

Hi, so today I have turned on my PC, but the monitor did not detect it.
I have unplugged and re-plugged all the cables and it still did not work.

I have then tried a different cable and monitor to but again it did not work.

Finally I decided to unplug my graphics card and plug the monitor into the integrated graphics card but once again it did not work.

The monitor does turn on and so does the PC but the monitor does not detect it being plugged in.

Any ideas on what can be the problem? (It all worked fine yesterday)

I plugged in two different monitors and both these monitors showed no signal. I plugged in a working video card from another computer and still no signal. I also moved the video cards to different slots and no luck. Does anyone have any suggestions? I appreciate your help very, very much.

I tried using another PCI-E port on the motherboard and the problem was not resolved.
When I plug my monitor into the integraded DVI port of the motherboard, I don't seem to have this problem.

I just can't figure out what is actually wrong with it.

A:Monitor doesn't detect that computer woke up.

Most of the time, it is the Video driver causing the issue. Uninstall the driver for the Video Display, and then reboot and let windows install the default driver. Also check the Bios to make sure that it is up to date. Windows 8.x has had a lot of random issues, with most being Video Display issues.

I would suggest not allowing the display to be placed into sleep, just set to blank the screen. If you are leaving the machine on for long periods, just turn off the monitor. When you get back to the computer, power it back on with the power button.

Hey i have bought new monitor since my old one sometimes work , sometimes doesn't.When i plugged in my new monitor which is LG TV 24MS53S Smart monitor the mouse has unnatural movements they sluggish and slow and hard to control same whit my tablet.After 2 days i noticed that under Device manager under Monitors it says Generic PnP monitor which is the monitor of my laptop (lenovo y510p) if i am not mistaken.While my monitor is under Audio inputs and outputs as LG TV-C NVIDIA High Definition Audio.I dont know if that what the problems is but i need help to fix my mouse.Also my monitor is connected via HDMI and also when i connect my mouse directly to my monitor it works fine but it can only be used for TV and apps, etc.

A:It doesn't detect my monitor as a monitor

The audio is referring to the audio signal for the TV. I want to make sure I understand you correctly, you are using the external monitor (LG) as your primary display, not dual monitors...?

If this is the case, go back into Device Manager, rt.click the Generic Monitor and choose "Update device driver". As long as the LG monitor is the primary display, and your laptop screen is off, 'Generic Monitor' is referring to whichever monitor is active. If you are using both monitors, then you should have two monitors being shown in device manager.

As far as the mouse feeling 'sluggish', do you mean it's just very slow? What is the screen resolution of your new LG monitor? Is it the same as the laptop monitor? If the resolution is higher, sometimes the mouse will seem sluggish when using a higher resolution, which means you might have to turn up the pointer speed in the mouse's control panel. Before you update the device drivers for the monitor (which may or may not be able to be updated), try reducing the screen resolution of the LG and test the mouse that way.

Never had this problem before with a motherboard not detecting a drive. Is it a BIOS issue that will be resolved once updated?

Check my spec page on user profile for my system info if this helps provide more info. It is running v4.1 and I can upgrade that to 4.3.

What happens is it will not detect the other HDD that windows is not installed on, but it didn't detect before any OS was installed on either drive, and this issue has been interchangeable between both HDDs. And each time Windows 7 setup detects both drives, not always - until I hot plug out and back in but it shows up then. Both HDDs show up when in windows but I run the risk of not being able to boot into windows having it connected. So as you can gather it is not RAID 0 as I normally have setup but AHCI for now. It is a new system and HDDs are healthy, pass all tests - and only a few months old.

I've not used AHCI mode before so howcome when I hotplug a HDD windows detects it but doesn't show up in computer, only under computer management? Only I could do with hotpluggin in a 2TB HDD I have that has backed up data on which I want to organised and move to another HDD so I can format it, I think it might be corrupted file system or something because when I hotplug it windows crashes whereas it never used to under my old system - this happens whether I use USB dock or SATA connection - hot plugging.

Advice much appreciated, thanks.

When my systems goes BSOD and restarts, I have that screen where I can choose which mode I should restart (safe mode, etc...) However Windows doesn't detect my keyboard during that screen and I am forced to wait 30 sec and boot in normal mode automatically.

Now this wouldn't be that much of a problem but I need to update the defective firmware of one of my HDD. And I use a boot disk to do that and of course the boot disk doesn't recognize my keyboard. So this became a major problem and I can lost my hdd data anytime now.

My mouse and keyboards both use an usb port, I suspect that I need traditional mouse and keyboard using traditional ports.

I have a traditional mouse but I do not have a traditional keyboard unfortunately. But I have converters from usb to traditional port for both mouse and keyboard.

What I tested:
1. plug-in the traditional mouse and reboot, result the traditional mouse is recognized.

2. use the usb to traditional port for the mouse and reboot, it doesn't recognize the mouse

3. use the usb to traditional port for the keyboad and reboot, it doesn't recognize the keyboard

Any clue on how to have keyboard recognized as traditional please?

I have a nice Logitech 120 headset that has great microphone quality, but it and any other microphone I plug in to my computer are not detected at all. The speakers in the headset work fine, but the microphone doesn't work. It has separate jacks for the headphone part and the microphone part.

My computer dual-boots with Windows XP 32-bit as well as Windows 7 64-bit, and everything works fine under Windows XP, so it's not the microphones or the hardware.

I tried updating my audio driver, but it appears to be up to date, and I tried using XP's audio driver under Windows 7, which didn't work at all.

Any help is greatly appreciated.

A:Windows 7 Doesn't Detect Microphones, but XP on same Computer Does

Windows XP handles some audio functions differently than Vista/Win7/Win 8. Thus the reason the XP drivers do not work.

First thought on the Win 7 drivers, use the Intel provided drivers for your motherboard, as a first choice. I had an older Win 7 PC with an Intel motherboard and only the Intel provided drivers worked correctly.

Hello, i have a problem with my soundcard.
This is a separate sound card, so it's not a part of my motherboard.
The name of the soundcard is: "Creative Sound Blaster X-Fi Xtreme Audio PCI Sound Card"
The card and my optical sound (i use an optical cable for digital sound, which no longer works when i switch to "S/PDIF" sound in sound devices.) no longer works. When i go to device manager, it doesn't even detect that i have my specified soundcard, which i absolutely do.

Also after the re-install, my computer feels really slow. I have 16 gigs of ram, a good CPU, and a good graphics card, so that is not the problem. If anyone could figure out or have an idea what could be wrong with those two issues, PLEASE do reply.

I fear that after my Windows 7 re-install, a ton of drivers are missing. I don't have my 'recovery hard disc' anymore, which contained a lot of stuff for my PC. The computer store who installed my sound card, graphics card and more, removed that hard drive. I didn't notice that before i had to do a re-install, and they don't have that darn hard disc anymore.

Can anyone help me? Do i have to do something in BIOS? I'll attach a DxDiag of my computer to this post! Please help me!

A:My PC doesn't detect my soundcard after Windows 7 re-install.

You are probably missing needed drivers. Since you have an intel CPU, you have a motherboard with an Intel chipset. Go to the motherboard vendor and download the needed drivers, including the Intel chipset drivers. One of the main things the chipset drivers do is define (identify) all the hardware devices on or attached to the motherboard.

I didn't see what the motherboard was in DXDiag, the BIOS should give you that information. Manufacturer and model. Then go to that manufacturers downloads for the specific model motherboard. If there are no Windows 7 drivers listed, Vista drivers are compatible.

In addition, since you are using a separate sound card, you need to disable the on-board audio (the RealTek) in the BIOS. Two sound devices can conflict which could cause some of your problems.

About a day or two ago, my computer really slowed down. For instance, winrar takes much much longer to extract a 50-70 mb file (before it would take 3 secs, now it takes around 15 secs). The music I play with VLC media player sometimes gets sloppy, music gets distorted when doing multiple tasks, something it didn't do before. In fact, just now as I was extracting a rar file AND playing music, the music sounded messed up. There are a lot of other indications of slowing down (defraggler -> analyze taking MUCH more time and freezing my computer at certain % intervals, 17, 35, etc).

so I ran a few virus scans, mbam, avast. and nothing came up. Does anyone have any idea what it could be?

Wow, that's odd indeed! Do you see them in Device Manager? If not, try and do a search for new hardware. Also, if your familiar with navigating the BIOS, make sure those devices didn't get disabled somehow. You may even want to try unplugging those devices, and adding them back to the system one at a time.

Greetings. I am experiencing issues with my system and would like to post my system info for additional support.

INITIAL SYMPTOMS: while surfing the internet, Windows detected a malicious file (notified via pop-up in taskbar), followed by an immediate system reboot. Windows would no longer boot. Upon further investigation, my boot drive priorities in the BIOs were altered. Once I returned to original boot order, system would still not boot into windows. I then ran MBR fix and was able to boot into windows successfully. No files are missing, but internet connection is much slower. Kasperski (installed prior to initial system errors) will no longer complete a full scan. Hangs at 60%. Additionally, Windows no longer recognizes it's existence as protection or firewall coverage. Also, windows takes about 5-10 minutes to shutdown. Used to take about 1 minute MAX. Uninstalled, and re-installed Kaspersky ... same issue (reset WMI to see if WIN7 would recognize Kaspersky, no luck. Called NortonLive support and they were able to install Norton 360 and insist that there are no longer any viruses or malware. Upon checking windows error logs, I am receiving numerous errors that I never logged before incident. Windows reports an io error with DRIVE 4. physically removed drive. no luck. Same error. I also noticed that Windows reports different SATA port connections vs. BIOS. Example ... in BIOs C:\OS is SATA CHANNEL 0. In WINDOWS under properties, its listed as SATA CHANNEL 2.

Well,

Yes, Win 7 has detected an audio device. What it's not detecting is that you have speakers plugged in.

Do you have a set of speakers you can plug into the back (green) speaker jack?

Or maybe a set of headphones into the front (green) headphone jack?

If it didn't detect any devices you wouldn't see those options.

Right now you're set to output audio to "Digital Out", it's set as the default output device, plug speakers in, select "Speakers" then click on "Set Default".

A:Windows 7 Doesn't Detect nVidia Graphics Card

Which drivers did you try, these?
NVIDIA DRIVERS 196.21 WHQL
Also, did you try running windows updates afterwards, specifically "optional" updates?

I have a Thinkpad T470 (20JN) with a 512 Gb NVMe drive  lense20512gmsp34meat2ta. Linux was installed & works well with no problems. But I'm struggling with Windows 10  setup.I could not make its installer recognize NVMe disk. At the same time Hiren's BootCD 15.2 based on Win10 recognizes my disk successfully.I tried to extract drivers from boot.wim using DISM and to add them back to original boot.wim (index:2), but it gave noany positive change.Can you please give me a hint how to make NVMe work ?

I upgraded a computer to Windows 7 because it had a corrupt Windows XP install and I wanted to save myself the hassle of reinstalling Windows XP.

I am now having a problem getting the PC to connect to the internet. It says that no Ethernet Driver is installed and it doesn't even detect an adapter with no drivers in Device Manager. I was expecting the yellow exclamation point!

I used Everest to get some details about PC in question and I hope I can post it here.

I found some drivers for this motherboard online and it worked for the audio but I just can't seem to get the LAN working.

This is the page I got the drivers from: http://www.ecs.com.tw/ECSWebSite/Pro...uID=24&LanID=0

I don't know how to install the LAN drivers.

The audio ones only worked when I did Windows XP SP3 compatibility on the EXE. I tried the same thing with the LAN but it said it couldn't find the NIC....am I doing something wrong?

A:Windows 7 doesn't detect/recognize Ethernet Adapter

It sounds very much as though your hardware is incompatible with Windows 7.

Before you tried to upgrade you really needed to download and run the Windows 7 Upgrade Advisor, which will flag up any hardware issues.

Windows 7 Upgrade Advisor - Download - Microsoft Windows

If you can find a Windows 7 driver for your LAN adapter you need to download it, save it to your hard drive and install it from there or go into device manager, select your LAN adapter, right-click it and select Update Driver Software.

My best advice to you is to reinstall Windows XP, and then run the Windows 7 Upgrade Advisor.

Hi,

I'm not sure if it's the correct section, but I have a big problem I need to fix ASAP. I'll describe it from the beginning:
1. PC with Windows 7 x64 worked completely fine one day, I used the sleep functionality.
2. The next day I woke it up. At the first sight everything was ok, logging in worked fine, so did Google Chrome, Filezilla and some other applications. But then I noticed that the sound doesn't work (including the volume button on the bottom bar), also an application that required access to drivers/etc/hosts threw an error. I tried to manually access it to no avail, Windows said it's inaccessible. I tried to restart my PC to see if it helps, but it wasn't the best solution because...
3. ... system didn't boot anymore. It went straight into the repair/recovery mode, I couldn't even safe boot it. The mouse didn't work in that mode and it was hard to do anything (I managed to run it but it did nothing, couldn't even see the error message due to no scroll possibility), so...
4. ... I used a YUMI pendrive with Windows 7 installer .iso. Mouse worked and I managed to run repair on disc E:, where the tool reported to see Windows. I ran it - this time it at least reported MissingOSLoader. I Googled it and followed this: System will not boot to Windows 7 Professional [Solved] - Windows 7 - Windows 7 1. and 2. didn't do anything - /bootrec scanos returned 0 systems. 3. seemed to worked fine until I restarted PC to see a NoOSInstalled error this time. I couldn't fix it so ... Read more

A:Windows repair doesn't detect unbootable Windows as installed

Using Bitlocker is a bad idea.

Reading that gave me a headache

But, mark your OS partition Active, then run startup repair until windows boots.

Hi,

Ever since the latest WP update (currently on WP8.1 Update, firmware 3051.50009.1424.0003) my Windows 8.1 PC doesn't detect my Lumia. I get "The latest device malfunctioned and Windows does not recognize it. There is also Unknown USB device (Device descriptor request failed) listed under Universal Serial Bus controllers in Device manager. Nothing under Portable devices section.

What I have tried:
- replacing usb cable (using original one) -> no luck
- soft reset phone -> no luck
- turning the phone off and plug it in -> no go
- manually uninstalling the device from device manager, restarting the PC and try again -> nope
- plugged brother's lumia 930 -> works like a charm

I'm slowly losing my mind, I have no idea what else can I try.

Any help is appreciated.

Edit. Ok so I've got access to laptop, plugging my phone there and the same problem happens at first - the device can't be recognized but a few moments later somehow it gets recognized and connected. The problem seems to be on my PC, can anyone help me out completely removing all the Phone drivers (including registry entries) so I can install them fresh?

Thanks

A:Windows 8.1 doesn't detect Windows Phone (Lumia 1020)

Welcome to the forum sukle.

Can't really help with your problem but a few ideas while you wait for one of the experts to come along and help.

Is your phone completely up to date ? Do you have the 8.1 update on your phone ?

I only have the Lumia 520, I have no problems with this on my 8.1 Update 1 Asus Notebook, I've just plugged it in so of course it's charging, usually charge through the mains adapter so very rarely plug it into the computer as everything can be done from the phone.

Sorry I can't help but I'm sure someone will be along soon to help you out.

I have a dell inspirion 530S with an intel g33/g31 express chipset, and a VGA splitter. When I have one monitor plugged in, without the splitter, the display is fine on that one monitor. However, when I have them both plugged into the splitter, it treats both monitors the same, with a crappy resolution, and won't detect that there are two. I have tried to update my graphics driver, but it says it's up to date. I am at my wits end, here. Please help.

I've seen a few forum posts and even youtube videos about this issue but so far nothing has helped. The problem I have is that occasionally my PC will not detect my second monitor at all, as in its not even shown in display and it can't detect any other monitors and I just get VGA no signal on my monitor.

Sometimes just restarting my PC fixes this issue but sometimes it doesn't, and I am pretty sure its not the connections as like I said, it works sometimes and other times it doesn't, also I do have a similar issue with my mouse and keyboard but I don't believe that is a windows 10 issue.

Just got a brand new computer and two monitors. Both monitors work just fine in the primary HDMI port. But the computer will not detect either monitor in the HDMI1 or HDMI2 ports. I've updated the drivers, disabled and enabled the drivers, gone to the individual websites and downloaded drivers, changed my screen display to extended...nothing. No matter what I do the computer will not detect my second monitor.

Here is what I have:
HP Omen 870c

Windows 10 Home

Hello everyone,

Recently, I've got a Samsung SyncMaster 2043NWX monitor. It's an used one, but it did work. My computer is an Acer Aspire M3920 (desktop), a more complete configuration can be found in my profile.

My desktop PC connects to my main monitor, an Acer P196HQV via an HDMI to DVI connnector, and my desktop PC connects to my second monitor, the SyncMaster, via VGA.

The problem is, however, the second monitor doesn't work. Win7 does detect a monitor connected via VGA in Control Panel > Appearance and Personalisation > Display > Adjust Screen Resolution, it says in the display box:

Code:
2. Display Device on: VGA.
In the Device Manager it only detected my Acer monitor, but after I downloaded the SyncMaster driver from the official site of Samsung, it detects the SyncMaster instead of the Acer monitor! This isn't the case in Adjust Screen Resolution.

The SyncMaster shows nothing at all, the blue LED, where I can tell the monitor is turned on from, flickers all the time, but the screen doesn't show anything.

I have tried reinstalling the driver, restarting my computer, installing the newest updates for Win7, making the SyncMaster my main monitor, turning off the Acer monitor, but nothing works.

I really hope any of you can help me, and thank you very much for the time you've taken to read this problem of mine.

PS
I have connected an extra monitor to my laptop running Win7 Ultimate x64 too without any problems, so I am not completely unexperienced... Read more

I'm running Windows 7 Home 64bit. About a week ago, I had an issue with internet connectivity which some fine people here were able to sort out for me. Basically, I found that I couldn't reliably access the internet unless I changed my DNS settings to Open DNS. After I did that, I found I could no longer print any documents even though Windows was still communicating with the printer. I ended up telling Windows to remove the printer and FAX in the hopes of just setting it up again.

However, that didn't work and Windows cannot find the printer at all. I've tried connecting via WLAN and via WPS but even though the printer finds the connection point to the router, Windows can't detect the printer.

My printer is a Canon PIXMA MX922. I've tried contacting Canon but chat but even their email tech support is giving me error messages.

I am not sure how to proceed from here. Could you please help?
