If you use similar cable connectors for both monitors, you can easily check the usability of the cable and monitor. You can temporarily remove a screen and check its functionality. Then replace it with the other with the same cable. If both work, check with the other cable. However, if you use USB connectors, you can also check all ports to see if any of the ports are dead.
If you use different connectors such as a VGA and an HDMI, you can only check one monitor at a time. Check the functionality of each monitor with a different set of cables. Let’s say the VGA port does not work, you may want to find a VGA to USB or VGA to DVI adapter. if the ports are available on your video cards.
However, although there are HDMI to USB adapters in the market, there may be other issues like degraded or no audio, as the quality of video and audio can change in the socket.
