Windows 10: Why is 1 of my 3 monitors suddenly not showing display when it was working before

woke up this morning and 1 of my 3 monitors had no signal. When i disconnect any one monitor the other comes back to life only allowing 2 monitors to be active. My gtx1050ti supports 3 monitors and even when i plug one display into my motherboard display output it still only allows 2 monitors to work.In the above configuration the VG248 which is 144hz is showing no display and weirdly shows up twice in Speccy and says its disabled.

4870x2 won't display at 1680x1050 at all!

OK. Now I know what ur problem is. Step by step:
1. Go to Catalyst Control Center
2. Click on the word "Graphic" right on top left corner. It will display drop down menu
3. Click on Display monitor and will see the list of monitor at near bottom
4. Right Click the monitor and select "Configure". It will show up the window
5. There will be 3 option to select. Select the middle one and then click on the tab which show the bar with 15%.
6. Drag the bar to max, and the screen will stretch to the native resolution 1680x1050.
7. Also click the tab with showing RGB drop down list and select the last one (it will change to image quality for pc).
That's it. Good Luck.

 

Suddenly, only 3 of 4 monitors working on windows 10

Hi NikosFreggidis,

Thank you for writing to Microsoft Community Forums.

I'll need a few more details to provide an accurate solution:

• How are the monitors connected to the main PC?
  
• Which version of Windows you are using? (To check, type: winver in start menu and hit enter.)
  

This issue is an indication of faulty drivers or incompatible graphic card driver. This issue can be fixed mostly by updating the drivers.

Method 1:

1. Press Windows
   and R
   key together on your Keyboard.
   
2. Type devmgmt.msc and hit enter.
   
3. Expand the display adapter option from the list.
   
4. Select the driver > right click on the driver and click on
   Properties.
5. Click on Driver tab > check if you have the option to
   Roll Back Driver.
6. If yes, Roll back the driver or uninstall it and restart the computer.
   

Uninstalling the driver will be automatically installed after the system is restarted. Check if the issue is fixed. If not, go to method 2.






Method 2:

Remove all the other monitors, connect the monitor which is not working with the main monitor.

1. Select Settings from the start menu> click on System > Click on
   Display.
2. Click on Detect under multiple displays. If it is detected, go to the next step.
   
3. Open the drop-down, select Show only 1> then "Keep changes".
4. And finally, open the drop-down again, select "Extend these displays" it will
   display on both the Monitor 1 and Monitor 2 now.

If both methods doesn’t fix the issue, you can follow Method 3.

Method 3:

Install the latest drivers from the manufacturer website.

1. As per the given information, there are latest drivers for your graphic card.
   
   Click on the following links and download the drivers.
   
   

• Chipset
  driver listed in the manufacturer website.
  

• Gtx770 Drivers
  for graphic card.
  
• GV-N770OC-4GD
  Drivers for graphic card.
  
  

2. Download the above drivers and install it.

3. Restart the computer and check if it is working.

Hope it helps.
