It would be used for gaming. It is important that it perfoms fast (It would be best if it could do so with better graphics as well). I mainly play Rainbow Six: Siege. Size isn't as important. The monitor i have now is 24 inches and I don't NEED a bigger one but I wouldn't mind if you know one where it is worth it. I don't really know anything about resolution, frequency and aspect ratio. Can you explain it or is it very complicated?
