yes, they work in a different way and after many years using a normal CRT I find that flat screen monitors look a lot worse. However, I think they have improved a bit over the years and the very expensive flat screen monitors are looking sharper.
The other thing to check (if you haven't already) is that you are running your screen at the "native" resolution, 1024X768 for a 15 inch and 1280X1024 for a 17 inch is the norm. Running at other resolutions will blur text.
