The next thing that you can check for is the cable connecting the monitor and your PC. If you connect your monitor to your PC using an HDMI cable, VGA cable, USB Type-C cable, or any other, you should check whether the cable is working fine. Also, check whether your PC and your monitors are correctly connected or not. 

You can try changing the cable connecting your PC and your monitor and check if that works or not. Also, check if your monitor turns on or not. If you have connected it to the power source, there’s some problem with your monitor if it still doesn’t turn on. 

If your monitor and PC have multiple ports for connectivity, then you must try changing the ports. For instance, if there are two HDMI ports on the CPU as well as 2 HDMI ports on the monitor, then you must try changing the ports and then check whether if it works or not.

If the second monitor you are trying to use is faulty, you may face such issues. However, if it is working fine on another PC, but not when you use it as a second monitor, you should move to the next method.
