First of all, sorry for my english. Im planning to upgrade my monitor and target Dell to be my next monitor. But Im in a big dilemma right now since there are so many models for Dell Ultrasharp such as U2412M(oldest), U2413, U2414H and U2415. Which one should I pick? Im an enthusiast gamer but watching movie sometimes. Some of my friends suggesting me TN Panel is good for gaming, but I prefer Dell because of the warranty services. But, you can also recommend me other brand and my budget is around those dell's price as I mentioned above.
