Viewing angle 170°(H) / 160°(V). Glass screen. Probably the
same kind of glossy finish as the Dell. If you work in an
area with fluorescent lighting over your shoulder, the glossy
finish would be a mistake. Glossy monitors should be used
in areas, where the user has full control of the room
lighting. My LCD is glossy, and there are no reflections
while using a single overhead light.

A review for the Asus.

Kind of a tossup.
My preference, is to see the monitors in person, if possible.
They look a lot different, when you see them for yourself.
