Windows 10 does not recognize second monitor
Bill Deaver
I have two Dell monitors and Windows 10 recognizes only one. Also, when in the recommended resolution of 2048x768 I get the message "1:Analog Input Cannot Display This Video Mode. Optimum Resolution 1280x1024 60Hz.

If you do the following, are you able to enable the second monitor?
  • Open a Run prompt
  • Type the following and click ok: desk.cpl
  • Select the second monitor
  • Choose "Extend these displays" from the Multiple Displays drop-down

Where do you find a Run Prompt in Win10?
Aug 7, 2015  • #3
Bill Deaver
I found the run prompt and got to the screen - no second monitor is recognized...
BTW, the "Cannot Display" info goes away at any resolution below 2048x758 but what results is not usable. Also, when 10 was first up and running both monitors were functioning on the 2048 resolution. I lost them trying to find a resolution in which everything on the screens was a bit smaller. At no time has the second monitor been recognized by 10...

Problem solved! Fooling around last night I noticed a way to change the Hz to 60 cycles and everything works now! except the system anly recognizes one monitor even though both are working with the background extended across both...

Glad to hear you were able to get it sorted! How are the monitors connected? If they're connected through something like a Matrox DualHead2Go, or an AMD Eyefinity setup, they would only show up as one large display to Windows. I would guess that your setup is something like this, because there aren't any monitors that have a 2048x768 screen resolution, so it's likely that each monitor is 1024x768 and they're combined into one large display

Yes! DualHead2go. Thanks!

I am having a similar issue I just updated to windows 10 for free and now my 2nd monitor doesn't work. I have tried plugging the 2nd monitor into the other ports ( I am running duel GTX 570's) and nothing worked. I tried typing desk.cpl and a screen came up but didn't allow me to change anything.

Windows 10 has some strange issues with some multi-monitor setups, hopefully it's something Microsoft will fix soon.

How I fixed the Windows 10 "second monitor cannot be detected" problem on my computer.

I have a relatively new Lenovo PC with Windows 8.1. I loaded the new free Windows 10. ("Free" = "Beta version, you have been warned.") During loading Windows 10 my primary screen suddenly developed white noise everywhere instead of an image. I ended up having to turn off the computer and restart it. It had white noise again, I turned it off and on again, and the second time the display came up on the primary computer. However, the additional display could not be detected.

I tried reloading Windows 10, thinking there must be a problem, but I had the whole white noise problem over again, turning off and on, completing two novels and a trip to the bathroom while I waited. Turned out that Windows 10 had indeed loaded.

After messing around with this for an hour and a half and reading lots of helpful tips from frustrated MS users, I did find a solution on my computer. Go to control panel, device manager, display adapter. There is a driver showing and it indicated a problem (small yellow triangle next to the name of the driver). At another help site, it was suggested to right click and "roll back" the driver. I right clicked on the driver. The "Roll Back" option was grayed out. But "Update" was available. I updated. After a few minutes of updating the primary screen switched to white noise again. I turned off the computer and turned it back on and Voila! both monitors were detected and operating just as they had been with Windows 8.

For those who have not used additional displays before, to avoid merely duplicating the display on both screens, go to Control Panel, Display, Adjust resolution. It should show two monitors, #1 and #2. At the "multiple displays" click the dropdown and select "Extend these displays." Note also that you can choose which display is the "main display" (where your program icons and system tray show). Also, you can drag the two images of monitors to put one to the left of the other. That helps so that the cursor flows smoothly side to side between the monitors without having to slide off to the right of one to enter at the left of the other.

Glad to help if this was helpful.

Brand new Surface pro 4, windows 10, dual monitor works very intermittently. first boot, surface display and the 2nd screen connected through a display port to VGA adapter works fine. I have windows configured to turn off the displays after x number of minutes of inactivity, and about half of the time, the 2nd screen does not come back. I can reboot, and again, about half of the time the 2nd screen comes back. additionally, if I unplug the screen, mini display port adapter, then plug it back in again, it may come back. I've searched around, and found reports of the same issue, but no solution. Anyone encountered this and found a fix? Seems windows 10 related.

*Edit* - one of the fixes I found suggested running something like DisplayFusion or UltraMon to manage the monitors... which, of course does not seem to completely fix the issue. DisplayFusion is current, Windows10 is currenty, Surface drivers are current.

Hi Keith,

I followed your instructions below

-Open a Run prompt
-Type the following and click ok: desk.cpl
-Select the second monitor
-Choose "Extend these displays" from the Multiple Displays drop-down

and my second monitor isn't popping up. It's connected with a HDMI cord and has worked fine before I downloaded the new Windows 10 version. Any idea why it's not recognizing it anymore and how to fix it?

Thanks,
Joe

@Joe: After you extend them, does it show up as enabled (blue) in the screen resolution settings? Or does it just revert back to being disabled (grey)?
Dec 3, 2015  • #13
JoeSmith
Hi Keith,

The resolution is grayed out. When I click "Detect", nothing happens. When I click "Identify", it only shows the number 1 on my laptop. Basically, it isn't detecting the second monitor at all.

And the way it's hooked up, through an HDMI cable, is the exact same way I've done it for years with the old Windows. How come Windows 10 doesn't recognize my second screen (tv)? And what do I do to fix this? Completely insane that this isn't working. It's basic stuff like this that doesn't work on Windows which makes people switch to Macs. The ease of use and system functionality seems much smoother on Macs. Anyway, I'm stuck with Windows so any help would be greatly appreciated.

Thanks,
Joe

Ok, here's what I got AMD Phenom II X6 1100T Processor 3.30GHz, 16GB RAM, Win10 Pro 64bit, XFX Radeon R7 260X, Compaq Q2009 Series Wide LCD Monitor and a Niko Monitor. The Compaq is VGA that I use a DVI adaptor. I got the Win10 64 driver from the AMD site.
For Win10 I got the free upgrade and did a clean install.

Like many of the other posts, only 1 monitor is detected. I tried rolling back the driver, I tried windows updating the driver, i tried the AMD site driver, I tried uninstalling the AMD driver and windows driver and re-installing the AMD driver.

During boot up, both monitors show the bios, they even both show the windows loading swirl. Right before it gets to the windows log in screen, one monitor goes blank and says no signal. After work tomorrow i'll try switching which plug each monitor goes in and one at a time in each plug. But because they both show the bios, i don't think it's a plug issue.

Any tips I should try would be helpful, i already tried everything else I've seen on this thread.

Took me a while to figure it out but this fixed my problem.

Device Manager --> Display Adapters --> Click on BOTH drivers and update them both. I also updated the driver in "Monitors" as well. Then I restarted my computer and it worked.

Crazy how Windows doesn't update your drivers when it upgrades to Windows 10. Beyond me how that is overlooked.

I have a similar problem, although it's not a big deal. I think it's a Windows 10 issue. Running 2 monitors off a video card on a desktop. Maybe 70% of the time on a reboot, only the main monitor displays anything. My workaround is to open display settings where everything looks like it should. (as though the second monitor was working properly, it isn't, just a black screen) I change to "show only on 1" Accept and keep. Then immediately change it right back to "extend". Accept and keep and both displays show the way I want.

Sometimes a reboot works properly, but more often than not, these couple of steps need to be done. Hope this helps if someone has a similar problem. Bit of a pain, but it's quick and easy until a fix comes along. :)

ive been looking everywhere for help and cant seem to find a fix.
My second monitor is only being recognized when it is turned off, soon as i power it on my computer doesnt recognize it anymore.
ive read its a possoble windows ten issue.
build info incase that helps someone figure my issue easier
i7 6700k
MSI z170a MB
EVGA GTX 970 FTW edition.

any help is greatly appreciated.

also the monitor im hooking it into is to my DVI port. i dont have a display port cable to test if it works with that yet or i would.

Jeffrey Gould649868
Premiierr, does your computer recognize both monitors if they are turned on prior to booting the computer?
Feb 9, 2016  • #19
Premiierr
yes and no. it does recognize them, however my second monitor is only is recognized when the power is off. soon as i turn the monitor on it no longer acknowledges it. ive checked different cables, and even other monitors (the other monitors tested were the same brand and model however) and same issue. but they worked just fine before. its also connected to the DVI port if that maybe helps with the issue. but again it worked before with no issues.

Jeffrey Gould649868
Whew, got me on all that. Only other thing that comes to my mind .... and you've probably already tried this ... is to try a non dvi cable (hdmi or displayport) if you can with that monitor.

I'm having a similar problem. I initially got a vga splitter and it was working, but it just mirrored the same stuff on both screens - it didn't extend. I must've messed up something in my settings because now when I plug in a monitor via VGA and a second monitor via HDMI it shows a blank desktop with programs lit up in my taskbar. I have two different home screens on each monitor and when I use the mouse, it will extend to both screens the way I wanted it to originally. however, when I click the tabs in the task bar to open the program, nothing happens. I cannot open any programs. All I can see is two different backdrops on each screen, with the mouse extending to either screen, but no icons on either of them.

If I try to operate by plugging my monitor directly into the VGA port, it will not work. It is just a black screen. It will only work if I use a vga splitter. Right now I'm currently operating by using one monitor plugged into one of the vga splits. Does this make sense? Essentially it works but not the way it is supposed to. How can I correct these settings?

I have the same problem...

I have basically tried everything you have written in this post, but nothing works.
I've updated drivers, tried with a VGA-cable, well, everything.

Do you have any idea of a solution?

Hi. I have an Lenovo Ideapad P400 and was going to connect two monitors and the second one is not recognized. Each my themselves no issue. HOwever, one is connected DVI to HDMI and the other one traditionally VGA. Never had issues before, but then again I have always used a port replicator. Not on this one. Is it not possible to have two external monitors connected to the laptop like this? When choosing detecting the laptop display is always 1, even when the lid is closed. Any ideas please?

Best,

Not sure on that one, sorry. You might be able to get more info from Lenovo support. Some laptops are only able to enable 2 monitors simultaneously.

@Einar: Your issue sounds like the backlight could be defective on the monitor. I've seen that happen where the monitor is technically working, but because the backlight is dead, you can't actually see anything on the screen.

I have the same problem. I have tried updating my drivers: the display adapter and the monitor one.
I have also tried to rollback the display adapter and update again.
I have tried downloading the intel drivers, but that didn't work either.

I am using an Asus Laptop to dual screen with my monitor using Micro HDMI to HDMI wire. It worked perfectly fine for the first 2 weeks, now my laptop doesn't even detect the screen.

Any help/suggestions will be appreciated.

  • Open the DisplayFusion Settings > Troubleshooting tab
  • Click the "Copy to Clipboard" button
  • Paste the text into a text file (please don't paste the text directly into your reply, the formatting gets garbled and makes it difficult to parse)
  • Reply with the file attached

I have tried the troubleshooting technique and have also restarted my computer in relation to the attached images. However, the second monitor was detected for 5 seconds maybe and then, went undetected again.

Maybe you can help me with this situation.

when I go to select "extend these displays" and hit apply a box pops up and says "the display setting could not be saved, please try a different combination of display settings.
for reference, I have one plugged into my radeon 7800 and the secondary plugged into the motherboard, its a pretty old monitor, but it worked fine until windows 10 decided to install itself..

Ok, I'm not sure what the issue would be there then. I would think it's an issue with the video card drivers, so the only suggestion I can make is to contact the computer or video card manufacturer to see if they support Windows 10.

Hi, seem to have a similar problem here
I use lenoovo z500, geforece gt 740m, win 10 with a pilot 2nd screen.
this first happened to me after upgrading to win 10. the pilot screen just suddenly not recognized and only gave me the no signal message.
i cannot remember how but i managed to find a solution online and fix it. i remember i had to do something in control panal>device manager and i think it was a problem with the driver.
now, a few months later i suddenly had a problem with the laptop's original screen-it was stuck dim. the solusion for this was to update the "generic pnp monitor" driver under "monitors"
once this update was completed the dim problem was fixed but now the pilot screen is again not recognized. what should i do???
tried updating the geforce driver
i'd appreciate a copy of your reply to neronar@gmail.com

thanks!!!

After reading through everything I was wondering if someone would be able to tell me if my issue is with my laptop or it's simply the hdmi cable I have.
I have my laptop plugged into my tv with a hdmi cable so I can watch tv on on a bigger screen with better sound. I have windows 10 but I've had that for months, way before I started using the cable, so unlike what a lot of people are saying in this thread it's not an update issue. The issue now is that whilst my second screen/tv is receiving a signal, or at least something, from the cable (because its black not blue) there's no actual display or sound coming from it. It's been working fine for months and only having a glitch and losing signal if I moved the wire by accident.
If the wire is damaged, is it possible its only slightly damaged? Which would explain why it's taunting me with a black screen and nothing more...

My LENOVO Laptop operates using Windows 10. I purchased an HDMI cable couple of months ago to enable me to watch movies on my television (Samsung). For the past few months everything was running fine UNTIL I recently watched a movie using a DIFFERENT Website. As a result, I now CANNOT project any movies or computer displays on the television screen BUT laptop display is OK.

BEFORE: Advance Display Settings - Multiple Display - Duplicate these displays. This will display 1 + 2.

NOW: Advance Display Settings - Multiple Display - Duplicate these displays. NOW displays 1/2.

Windows 10 is a virus that wrecks perfectly working old computers and microsoft and the computer manufactures are profiting from it. I might never buy another pc again as I've seen it wreck friend after friend's computers. I wouldn't recommend installing it. Just keep your original windows version. I've updated lots of computers over the years from one version to the next and never seen the problems that windows 10 is causing.

hello, my laptop which is a DELL is facing the same problems as my lenovo. The DELL laptop is using Windows 8 while the lenovo is using Windows 10. Previously i was able to duplicate the display from my laptop to the TV screen using a HDMI cable (both laptops could do it). But now it won't duplicate anymore because apparently there's "no signal" even though the tv detected it. As can be seen from the attachments, I believe that both screens should be labelled as "1" and "2" but now it says "1/2". is this the problem? and if so, how do i rectify it?

please help me! thanks! =)

Hi,
Just FYI, to all whos having trouble setting up their dual monitor.

I have recently purchased Toshiba Satellite L55-C i7 6700 HQ and was trying to setup Dell monitor as a second monitor using a VDI(Dell) to HDMI(Laptop) cable.

It dint work as plug and play.

Did restart multiple time and still no good.

Solution:
Went to Device Manager - and updated the driver automatically.

It solved the problem.

Hope that helps.

Okay, guys.

I don't know if you guys fixed your issues, but here is how I resolved my issues:

I went to control panel > device manager > display adapters, and then I opened the little 'folder'.

It gave me my driver and it said it had a problem, so I right-clicked and selected UPDATE, but it said that the driver was already up to date.. sooo, I right-clicked again and selected "DISABLE" - then, I re-enabled and VOILA! The issue was solved!

I am in exactly the same position mate. One of my computers has got two monitors plugged into it. Sometimes I can switch the computer on and both monitors will come on with extended display, However, today it took about four reboots and then shut down and starts before the second monitor came on.

On another note, the computer I am on at the moment uses Windows 7. I have two monitors plugged into it and there's never been a single case where the second monitor has not come on when I put the computer on.

I solved my specific problem after a day of troubleshooting.

Essentially, the HDMI output to my second monitor connects to the motherboard of my PC. The VGA connection of my main (working) monitor connects to the GPU. There is also a VGA port on the motherboard so I switched the working monitor to that and it didn't work. I therefore wondered if updating GPU drivers didn't actually affect those connections and I actually needed to update the graphics rendering inbuilt into the CPU. I looked in Device Manager to update the drivers for the on board GPU and it wasn't listed under Display Adaptors. I then booted into UEFI (BIOS) and checked the video adaptor settings.

It was set to AUTO, which means that it prioritises the graphics card over the inbuilt graphics. I changed it to "IGE" so it prioritises the inbuilt graphics. I had to reboot twice, but after that my second monitor came up!

That was the damnedest thing! I was doing everything I could think of to try to get it to recognize my second monitor and nothing was working. It had been displaying the same screen on both monitors but every time I clicked 'Detect' it told me that it couldn't detect a second monitor.

Then while I was reading the discussion in this forum, the screens went black for a few seconds and came back on having automatically switched to an Extended display, now recognizing both monitors. Crazy! I think that Windows 10 was just doing some behind the scenes downloads to set this up for me without letting me know it was working on it. (The computer was making a lot of clicks, as if it was setting something up).

So maybe I just need to leave the new computer alone for a while as it talks to the internet and gets all the drivers it thinks it needs without telling me what it's up to... :|

Good Evening,

I need some assistance. I have purchased a Lenova desktop PC with a NVIDIA quadro graphics card installed. I am trying to use a Hannspree monitor and either a LG or Dell monitor along side it.

My issue is the second monitor (LG/Dell) isn't being detected by Windows 10. I have looked into the BIOS and changed settings in there but all I have managed to achieve is to make the second monitor come alive and the first monitor go off!!

They are connected via VGA & DVI. The DVI is connected to the graphics card and the VGA is connected to the onboard card.

Any suggestions/help would be greatly appreciated.

Thank you.

Happy new year! I have a lenovo with intel hd graphics family. at first it would have one screen with 1/2 on it. then I updated drivers for the intel, now the intel identifies the second screen, but when i go to "detect", didn't detect another another display. Trying to stay vga (ya i know old school) but for use that's what's available right now where i'd be trying to go dual display. Is there a specific driver needing updated for the vga port? Or another driver i need to update? I ran windows update and everything is up to date. ran somethings individually, up to date. By the way, I got this lenovo about a year ago, i've never been able to go dual display.

I have an MSI laptop and I'm using a second display "Dell".

Windows 10 simply kept saying something like display not recognized, identified both as 1/2, so it was duplicating the display with the resolution of the Dell laptop display.

Detect didn't work, changing display settings to "Extend" didn't work.

This worked for me: "Control Panel" > "Appearance and Personalization" > "Display" > "Project to a second screen".

I just had this issue recently with my Windows 10 not detecting another display monitor. It was perfectly fine for almost 5 months after I installed Windows 10 until suddenly my Vizio tv showed no signal. I tried checking the port and the cable with another laptop having Windows 7 and it worked perfectly fine.
I went to Device manager next and checked the display adapter tab. Disabled and again enabled the Intel display drivers and VOILA, it started detecting again. This might be a bug in the recent updates with Windows 10 because I remember updating the night before this issue happened.

Hope this helps. Thanks
