X-bit Labs has published a LCD monitor buyer's guide, you can check it out over here. They provide tips on selecting the best 17", 19", 20-22", 24-27" and 30" LCD displays.
In this article I will try to sum up my experience in testing LCD monitors and answering the frequent question, “what monitor to buy?” Our regular reviews can give you an answer too, but it is a daunting task to read through all of them and systematize that bulk of information in one’s head. Most users take a different approach. They somehow identify the models they may be interested in and then look for appropriate reviews.
So, the purpose of this article is to point out the most interesting (from my point of view) models of monitors in terms of technical parameters, exterior design and ergonomics without overloading you with technical information.
