contrast's value is over-rated
what's really important is that the color you see will be correct and exact.
higher contrast doesn't necessarily indicates higher quality
as you can see, color quality for the L1720B is rather avrage and should satisfy you
anyway, in my opinion 1:240 is very low, too much low.
and I know that the contrast is over-rated, but in this monitor its a joke. from 1:550 to 1:240 ?
take for example the samsung or the 1720B, the real contrast is only 1:50 less the written contrast (1:600->1:550, 1:450->1:393)
in the 1730 case, the real contrast is 1:310 (!!) less than the written contrast.
maybe this monitor is quite good, but in my opinion its a big failure of LG.
am I wrong?
