Windows 10: External Second Monitor not detected after Bios Update

Hello All!


I have a new HP Spectre x360 convertible laptop and a Dell s 2740 external monitor.


I restarted my machine and the bios updated happened automatically. Once it happened, I could not use my Dell monitor at all.


It says "there is no signal coming from your computer. Bla bla bla ………"


Steps taken-

For now, I have uninstalled the display driver and reinstalled it after restarting.

Changed HDMI cable and USB-c hub.


Does anyone know the resolution? Please help!

Second monitor not detected

After a recent update, my external monitor stopped working, and the Display option has vanished from the Control Panel. I did find the settings and Windows 10 does not detect the second monitor. I checked for updates in the Device Manager and Windows Update
and both say the best drivers are already installed. What can I do to get Windows to detect the second monitor? Thanks

 

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 It could be due to your video driver being outdated, incorrect or faulty.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.

 

Second monitor not detected after update

Hi Tom,

There are several reasons that could have caused the issue you are experiencing. One of these is the update you previously performed in Windows, either it was not configured properly by the system or the update components were corrupted. Kindly answer the
following questions for clarification:

• Have you tried updating the monitor and display drivers?
• Have you tried to use another user profile to check if the issue re-occurs?

Furthermore, we suggest that you add the other monitor manually. This is to ensure that the second monitor is still connected after the update. Here are the steps:

• Type connected devices and open Connected Devices on the
  Windows Search bar.
• Click Add devices.
• Select the Second screen.
• Pick one of the 3 options: Duplicate, Extend, and the Second screen only.
• The Duplicate option will duplicate the primary display to secondary display.
• The Extend option will unite two monitors so you can use them both as one.
• The Second screen only option will, obviously, disable primary and use only the secondary monitor.
• Once you’ve chosen the preferred mode, save changes.

We're looking forward to your response.
