Monitor features include resolution, refresh rate, response time, screen size, and connectivity. By understanding the needs of the user and what they want out of the monitor is important when buying a monitor.   If you are looking for an affordable option on a 24-inch monitor with HD resolution, wide viewing angles, and fast response time then you should consider one that is 1080p with a 144Hz refresh rate. If you are looking for more features then you have to pay more for it.
