How to fix the issue of Windows 10 Not Detecting Your Second Monitor? – Guide
Windows 10 can’t identify a second monitor if the first monitor is in the same room as the computer. This is because Windows 10 relies on a feature called “DisplayPort.” If one of your monitors is in another room, Windows 10 won’t be able to see it and will report an error.
If you have a secondary monitor and your computer doesn’t recognize it, you can connect it to the setup using a cable or an adapter. If your computer still can’t find the monitor, you may need to try changing some settings on your device or your computer.
In Windows 10, there are a few ways to troubleshoot external monitor connection issues. One way is to check the external monitor’s connection status. To do this, open the Control Panel and click on the Hardware and Sound icon. Then, under Connection Status, you’ll see a list of devices that are connected to your computer. If one of the devices in this list is not working properly, it can be fixed by changing its settings.
