I'm using Mac 17" with resolution of 1920 x 1200 with longest side of the screen measuring 14.5". In photoshop CS5, Preference > Units & Rulers, what values shall I put in the box "screen resolution". At the moment its set at 72 pixels. If I use 1920/14.5, it should be 132 pixels.
I tried 72 and 132 pixel and I do not see any difference in the image. So I like to ask what's the purpose for this box?
