There is no definitive answer to this question. The price of computer monitors can vary greatly, depending on the size, type, and features of the monitor. In general, though, you can expect to pay anywhere from $50 to $1,000 for a computer monitor.
One important factor that affects the price is screen size. Larger monitors tend to be more expensive than smaller ones. For example, a 27-inch monitor typically costs more than a 21-inch monitor.
Another major factor that affects the price is the type of display technology used in the monitor. LCD (liquid crystal display) monitors are generally less expensive than OLED (organic light-emitting diode) or plasma displays. And 4K Ultra HD monitors tend to be pricier than traditional Full HD displays.
Additional features such as built-in speakers or USB ports can also drive up the cost of a computer monitor. So it’s important to consider what features are most important to you before making a purchase.
