For example, the default screen resolution for monitor 2 is 1366 x 768, I can individually adjust settings for just that monitor without affecting the main one. The Display Setting window will come up, and here you can make individual adjustments for each monitor. Right-click the desktop and select Display settings. If you have unique requirements, you can adjust these using Display Settings. Here’s an idea of what setting up a second monitor using a laptop looks like. In the example below my second monitor on the right. Extend will place a copy of the Windows desktop on the second monitor with its options separate from the main monitor. In my case, I need some additional screen real estate so I will go with the Extend option. This will bring up a menu with a list of options.
The first thing you need to do is connect the monitor to your HDMI, DVI, or VGA port on the PC.
