I'm looking to buy an external monitor for my 15" MacBook Pro and use it as the only display. Ideally the monitor would be 23-24" for the screen size and cost no more than $200. It doesn't need to have 4k or ultra HD resolution, but it should be clear and easy on the eyes as I'll be doing a lot of reading and coding. I already have a comfortable mechanical keyboard and mouse, but am unfamiliar with what's commonly used as the monitor.
