There are a few reasons gamers might have 2 monitors. One reason is that one monitor can be used for gaming and another monitor can be used for other tasks, like working on a project or watching TV. Another reason is that some gamers prefer to use multiple monitors to improve their gaming experience. For example, if they're playing a game on one monitor and using the mouse and keyboard to control the character on another monitor, having both monitors close by makes it easier to do so.
