There are several ways to play games on dual monitors:

1. Extend your display: You can extend your desktop across both monitors, which allows you to drag windows and other content between the two screens. To do this, you'll need to make sure that your graphics card and operating system support multiple displays.

2. Use a game that supports multi-monitor setups: Some games, like racing simulators and flight simulators, are designed to take advantage of multiple monitors. These games usually allow you to set up your displays in a variety of configurations, such as side-by-side or top and bottom.

3. Use a third-party program: There are several programs that allow you to play games on dual monitors by splitting the game window across the two screens. One example is the program "Dual Monitor Tools," which is available for free and works with a variety of games.

Regardless of which method you choose, it's important to make sure that your graphics card and operating system are capable of supporting dual monitors. You'll also need to make sure that your monitors are properly configured and calibrated for the best possible gaming experience.
