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 It could be due to your video driver being outdated, incorrect or faulty.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

 

Windows 10 can't detect my second monitor

Thank you for confirming. We can do the following:

When the second monitor is not detected, we need to isolate if it's the monitor, the cable connecting them, or the port. We suggest that you remove your 1st monitor, then use the 2nd monitor as your 1st monitor. After that, connect the 1st monitor as the
2nd monitor.

Usually, this it's driver-related. Windows 10 won't be able to detect the 2nd monitor if the monitor driver is out of date or faulty. We recommend, rolling back to the previous installed graphics driver and monitor driver if it updated. Otherwise, update your
graphics and monitor drivers on the Device Manager. To do so, follow the steps below:

• Type Device Manager in the Cortana search bar and press Enter.
• When the Device Manager window appears, click the Display adapters and right-click the item below.
• Select Properties, then Driver tab, and click Roll Back Driver and follow the on-screen instructions.
• Expand the Monitors, then right-click the second monitor and select Properties.
• Click the Driver tab, and click Roll Back Driver and follow the on-screen instructions.

If the issue persists, update the drivers. You can manually update the driver by visiting the websites of your graphics card and monitor manufacturers to get the fully compatible drivers for Windows 10. You can run the Find
and fix problems with devices and hardware to automatically check for driver updates. Additionally, we'd like to know the make and model of your graphics cards and monitor?

Post back anytime at your convenience.

 

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.
