Fix problems when running more than one screen on one device in Windows systems

There may be times when you encounter problems with the second display or connecting the two screens together. Here are some tips that you can use to solve these problems.
No Signal
If you find that there is no signal on the second screen, this means that the data is not passing from the device to the screen or that the device is not properly connected to the screen. There are several ways to solve this problem.
First: It is possible that the screen is connected but the device does not recognize it, so you must make sure that the cables are connected correctly. If the problem persists, you must turn off the screen and then turn it back on to see if the system recognizes the new screen or not.
After that, we try the Windows Detect tool to find out whether the device has recognized the new screen or not. To find out, we must follow the following steps:
1- Right click on the desktop and choose Display settings .
