Most of the Lcd panels today are cheaper Tn panels than models like IPS,PVA and MVA which have better colors and wider viewing angle.I bought a Hannspree 27.5 inch LCD awhile back and although I love the screen size someetimes the colors dont look quite right.Especially the black and dark colors.Its not just drivers .Playing games or watching movies you will probably be able to a difference between the types.Tn panels offer advantagesof being cheap and fast response times which the more expensive panels wont have.But people doing a lot of graphics work really cant use them(TN that is) due to not displaying true color's.
here is an excellant detailed writeup of the differences even though it is somewhat dated.
