Windows 10: Second monitor detected but won't connect.

Hello, it's just as the title says. I recently updated Windows, and Nvidia, and now my second monitor is detected, but it will not connect. I have rolled back on both Windows, and Nvidia updates to no avail. I have tested the cable, and the monitor to make sure they weren't the cause but they both work fine. If anyone has any ideas or solutions, they would be greatly appreciated. Please let me know if any information is necessary.I have a Ryzen 5-3600 Processor, an Nvidia RTX 3060Ti graphics card, and a Tomahawk B450 Motherboard, if that's important.

:)

 

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 It could be due to your video driver being outdated, incorrect or faulty.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

 

Windows can't detect second monitor connected through USB

I'm trying to run a second monitor (HP1740) on my HP Compaq dc7900 running Windows 10. There is only one VGA port, so I've connected with a USB-A to USB-B cable. Windows does not detect the second monitor. Any suggestions?
