Windows 10: the TB3 stopped detecting the monitor

I have a gaming laptop and I got a new gaming monitor 165hz and g-sync capable.I have recently bought a Thunderbolt 3 to DisplayPort adapter LAPTOP<--TB3---DisplayPort 1.4-->Monitor, I plugged everything and turned on the laptop and the monitor everything was running fine, I was checking the options of the monitor from the builtin nob and I turned it off, turned the monitor back on, it show me a notification saying " Display connection might be limited" , plugged unplugged to the TB3, same notification. and when I click on it, it takes me a useless page, tried everything in it. and with some digging of my own, noticed that the device is being detected as a billboard device when connected.​

luckily my laptop comes with tb3 and usb-c plug from the other side, so I switched to the other side, the monitor working fine, but I'm planning to use it on 2 monitors.


now my question is, how can I make my TB3 recognize the monitor as monitor again not billboard.


Windows 10 home version 1809 build 17763.973

laptop : Asus Mothership GZ700

Monitor : Gigabyte Aorus FI27Q-P

the Cable used : Club3D The USB Type-C to DisplayPort 1.4

Windows 10 stopped detecting 2nd monitor

I've restarted the computer (several times), and it's not showing any signs of detecting the 2nd monitor.

Ever since it stopped working, there's only '1' Display option; clicking 'Detect' in Multiple displays results in the message
"Didn't detect another display"; the Device Manager only lists one monitor (screenshot below); and it has stopped allowing me to select other projection modes unless I connect to the 2nd monitor wirelessly.

I'm using an HDMI cable for the 2nd monitor, and have tried both HDMI ports on the monitor unsuccessfully. The monitor models are Dell E2414H and LG 24J4840.

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.

Hello Chaya,

When 1 and 2 are posted under the Display option, it means that the device is detecting a video input. Concerns related to signal input could be associated with the driver or the hardware component of your device. To help us determine the appropriate troubleshooting
steps that can resolve your concern, we would like to ask the following questions:

• Do you see your monitors under Display settings? To check, right-click on the blank area on your desktop and select Display settings.
• What projection option did you choose for your monitors? To check, press Windows + P on your keyboard.
• What is the make and model of your device?
• How are the monitors connected to your device? Examples of connections are VGA, HDMI, and DVI.

In the meantime, you can follow these steps on how to configure your other monitor on Windows 10. To do this, follow the steps below:

• Check the back or the side of your device to see if it has any of the connectors below.
  
  
  
  
  
  
• Connect the secondary monitor to your laptop via VGA,
  DVI or HDMI port.

  Display settings.
• Click Identify to show numbers on corresponding displays (1 is the primary).
• Click the Multiple display drop-down list, and then select
  Extend these displays.
