We compared all the other LCD screens that have a display resolution of 1366 x 768 pixels to this PC monitor and we think the Hanns.G HP195 (£75.75) which is cheaper; or the Samsung LS19C20 (£92.39) which has a better Rating are also worth considering.
If the display resolution of this PC display is too few for you then you might also want to consider the P1913 (£69.00) (1440 x 900), or the P1911 (1440 x 900) both from DELL which also has a higher Rating.
