Windows 10: Unable to detect third monitor

I recently acquired a HDMI splitter and was hoping to connect my laptop with an external monitor and a TV. However, it doesn't seem to be able to detect the TV. I know the connection works since the TV was able to duplicate my external monitor but I was hoping that I could extend it which I couldn't since it won't detect. I suspect a hardware issue. Any help?

Windows 10 Update - Now my dual monitors do not work

Hi,





One of the possible reasons why Windows 10 was unable to detect your dual monitor is an outdated or incompatible graphics driver. To best address your concern, we need you to answer the following questions:

• Which Windows 10 build are you using?
• Have you already tried performing the troubleshooting steps suggested by
  Mauro Cavallin on June 16, 2017?
• Are both of the monitors not working just like what the original poster was experiencing? If yes, have you tried disconnecting one of the monitors? What was the outcome?
• What troubleshooting steps have you done so far?

We will be waiting for your response.

 

Windows 10 stopped detecting ThinkVision M14 monitor

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are unable to use ThinkVision M14 monitor on your computer. I’ll help you with the issue.



However, please let us know:

• Are you aware of any changes made to the computer recently?
  
• What is the make and model of the computer that you are using?
  

As you have mentioned that you are able to use the monitor with a different computer, I suspect it could be an issue with the drivers on the computer. I would suggest you to check for hidden drivers on the computer and try to update them. Refer the
steps mentioned below:

1. Press Windows Logo key + X, and select
   Device Manager.
   
2. Click on View and select
   Show hidden devices.
   
3. Expand Monitors and check if there is any
   hidden device.
   
4. If there is any hidden device, right click on it and select
   Update Driver.
   

You can also install
ThinkVision M14 Monitor Driver and see if that makes any difference.



Since you are using a USB-C adapter, I suggest you to refer the article on

Fix USB-C problems.



You may also try updating the Chipset drivers from the computer manufacturer’s website and then check if the Monitor is detected.



Let us know the results.

Second monitor not detected

Hello,

May we know if you've already tried the suggestion provided by Robert Aldwinckle on forums on this

thread?

If Windows can't detect your second monitor, it's usually a driver problem. It could be due to your video driver being outdated, incorrect or faulty. It's also possible that your monitor driver is causing the problem.

Since the issue occurred after the latest update, it's possible that the video or monitor drivers require an update. Try looking for the updated version of the drivers on the device manufacturer's website and follow their instructions.

If the issue persists, try to roll back the drivers to the last good configuration. To do that, you may follow these steps:

• Right-click the Start button and select Device Manager.
• Right-click your device driver, select Properties, and browse to the
  Driver tab.
• Press the Roll Back Driver option if available, and Windows 10 will begin the process.

Let us know how it turns out.
