1. Make sure your PC has two video output ports. If your PC doesn't have two video output ports, you can purchase a video splitter, which allows you to connect two monitors to one video output port.
2. Connect one end of a video cable to your PC's first video output port and the other end to the first monitor's corresponding input port.
3. Connect the other end of a video cable to your PC's second video output port and the other end to the second monitor's corresponding input port.
4. Turn on both monitors and your PC.
5. If your PC doesn't automatically detect the second monitor, right-click on the desktop and select "Display Settings."
6. Under the "Multiple displays" section, select "Extend these displays."
7. Drag and drop the monitors to arrange them in the desired positions.
8. Click on "Apply" to save the changes.
