Before purchasing a second monitor, verify that your computer can support multiple displays. Look at the back of your desktop PC or the sides of your laptop for available video ports. Common ports include HDMI, DisplayPort, VGA, or USB-C. Most modern graphics cards support at least two monitors, but it's worth checking your computer's specifications or graphics card capabilities online.

Once you've confirmed compatibility, ensure you have all necessary cables to connect your second monitor. If your monitors have different input types, you might need an adapter. For example, if your computer has HDMI but your monitor uses DisplayPort, you'll need an HDMI-to-DisplayPort adapter. Also consider the length of cables needed based on your desk setup.

Place your monitors on your desk in your desired arrangement. Consider ergonomics - the monitors should be at eye level and about arm's length away. Most users prefer monitors side by side, but you can also stack them vertically. Ensure both monitors are stable and have adequate ventilation space.
