I, a proud owner, can't tell you dot pitch, but will help figure out dpi. My monitor is 12" x 18.5", for an exact diagonal dimension of 22.0511". This gives 222 square inches. With a max resolution of 1600 x 1024, that's a total of 1,638,400 individual pixels. So, 1638400/222=
7380.18 dpi.
I don't know exactly what else to tell you--if you have any questions, I'll try my best to answer. I definitely recommend the cinema, certainly because of its size, but also because of its lack of size. LCDs rule!
