at the left, right one is NEC PA272w
There is hardly any difference between 4K screen and NEC's 2.6K in resolution wise, Dell's gamut is 99% cover of sRGB
whereas NEC's gamut covers 99.7% Adobe RGB. Dell looks nicer on this photo, but actually NEC is much better in many
ways, so it was silly expenditure for Dell's 4K screen even though it costs one quarter of NEC's. 4K movies look not so
impressive, however high density photos look a little sharper on this Dell's monitor than on NEC's.
