Or maybe I did not understand the meaning of Resolution.
This is the code I used -
I get 120 as my system resolution, and Full Screen Area as 1366x768 (~14" diagonal screen).
I checked with two of my colleagues who have mathematica installed. The one with a ~15.4" diagonal screen got Resolution as 96 & Full Screen Area as 1366x768. This made sense, sort of, a bigger screen is lesser dense pixel-wise for the same pixel screen area. But when I checked with another ~14" diagonal screen laptop, mathematica returned Resolution as 96 & Full Screen Area as 1366x768. This doesn't make sense, two physically equivalent screens with same pixel area but different resolutions.
Both my laptop and the other 14" laptop got similar dpi's of 112, and the 15" laptop returned a dpi value of about 100. I did the math and these numbers fit it just well.
So is Mathematica wrong here? Or am I barking up the wrong tree for the dpi value?
I am new here, so thanks for any help extended, in advance!
