Buying the right monitor for your PC is crucial, especially if you spend many hours in front of it either because you work from home or you're an avid gamer. It's not as simple as just spending more to get more, though. Different monitors are better suited to different tasks so knowing which one is right for you is just as important. There are four main considerations: size, panel type, refresh rate and resolution. If you only use your PC occasionally then you can get away with a modestly sized screen: say, 20-24 inches.
