Thank you for your remarks.
I have nothing invested in these NEC displays, but still, I fail to
understand how a viewing angle smaller than 160 or 170° can be seen as
lacking. I am quite satisfied with my ACD's viewing angle, which is probably
about 70° (35° left and right of dead center) before a marked shift is
Incidentally, the viewing angle of the NEC SpectraView (MultiSync LCD2180WG)
is listed as 176° Vert., 176° Hor. (88U/88D/88L/88R)@ CR>10. That of the
Eizo CG220 as 170°, 170° (at contrast ratio of 10:1), which is the same as
that for the CG210 and CG19.
Can anyone please clarify this confusing set of information? Or lead me to a
URL that does that?
