All lcd displays I've used for a decent amount if time, so far (not so many, and just on laptops, and that's why I am asking ) had this problem:

They have a preferred, "native" resolution. When switching to any other one, the image would look blurrier or somehow much worse in quality. Is it still true with current, most recent LCD displays (or, do you know if there are some specifically NOT affetced by this problem)? Other than that I'd really love to buy an LCD now...
