Except for notebooks, monitors are necessary for computers, because you need to buy a monitor for every computer. In case of notebooks, you do not have a choice when it comes to your LCD screen, but in case of monitors the decision is up to you. There are two main types of monitors in general: CTR and LCD. LCD monitors are considered to be superior as they are slim, take a lot less space and perform very well. On the other hand, CTR monitors are sometimes used by demanding gamers or graphic designers as they have better color fidelity, viewing angles, and contrast. Even though CTR monitors have some advantages, most experts would recommend LCD monitors. That is not only because they are slim, but also because they are brighter and offer clearer text.
