Monitors, like computers, come in all different shapes and sizes. Depending on the task you plan to use the display for, the price and features can vary significantly. Gaming monitors are some of the most popular monitors on the market today. This is because the power and many features of gaming monitors can provide benefits in areas other than gaming. 144Hz monitors are capable of very high refresh rates and some of the smoothest gameplay possible, while improved color accuracy is ideal for professional animation and video editing. Specific brands such as NVIDIA and AMD also have proprietary technology that you can find within monitors that will work to reduce latency and improve response times. For example, G-sync monitors use the technology found in NVIDIA GPUs to synchronize the refresh rate of the monitor to the graphics card reducing screen tearing. Freesync is AMD's alternative to G-sync and uses similar technology to reduce screen tearing when using AMD graphics cards. In addition, AMD graphics cards can use supersampling to virtually increase the display's resolution and enhance image clarity. Luckily, there are many gaming monitors out there that are compatible with G-sync and Freesync technology.
Finding the best gaming monitor for you has more to do with matching the display to your system and not the overall power or features of the screen. This is because your monitor can only display what your gaming PC is able to output. This means that just because a monitor is 4K does not mean that your PC can display games at 4K. Depending on the type of game, monitors can prioritize refresh rates and response times over resolution because these specifications have the most significant impact on how it feels to play games. Playing in higher resolutions is possible, but hardware requirements quickly rise along with image quality.
