There are generally 3 realms of decision when one is buying a computer monitor. I will be covering those 3 subjects here. 1. Flat screen/Non-Flat screen Almost all monitors made today are flat screens. However, if you have a low budget, getting an older monitor with substantial backs can be a good option. I do recommend you get a flat screen monitor though, because they have many pros versus older monitors regarding space, quality, and of course the superficial aspect of a sleek, flat screen monitor.
