here are different ways to skin the cat:
3007WFP $1,274
30" 2560x1600
total dots = 4,096,000
each dollar buys 3,215 dots
total surface area ~ 384 sq in
dots per sq in ~ 10,651
each sq in costs $3.31
2407WFP $719
24" 1920x1200
total dots = 2,304,000
each dollar buys 3,204 dots
total surface area ~ 246 sq in
dots per sq in ~ 9,361
each sq in costs $2.92
2007WFP $359
20" 1680x1050
total dots = 1,764,000
each dollar buys 4,914 dots
total surface area ~ 171 sq in
dots per sq in ~ 10,321
each sq in costs $2.10
E207WFP $260 (old model?)
20" 1680x1050
total dots = 1,764,000
each dollar buys 6,785 dots
total surface area ~ 171 sq in
dots per sq in ~ 10,321
each sq in costs $1.52
if you put 2x 24" together, you will get:
-- 492 sq in (28% more than 1x 30")
-- 4,096,000 dots (13% more than 1x 30")
-- costs $1,438 (13% more than 1x 30")
if you put 2x 20" together (cheap $260 model), you will get:
-- 341 sq in (89% of 1x 30")
-- 3,528,000 dots (86% of 1x 30")
-- costs $520 (41% of 1x 30")
other considerations not explored:
-- dot pitch size
-- image brightness
-- response time
-- color quality, etc.,
