Assuming all LCD/TFTs have square pixel elements

15" 1024 x  769 is  4:3
17" 1280 x 1024 is  5:4
19" 1280 x 1024 is  5:4
19" 1440 x  900 is 24:15 or to put another way 14.4:9 or 4.8:3
                         (20% wider than 4:3 / 28% wider than 5:4)
20" 1400 x 1050 is  4:3
20" 1600 x 1200 is  5:4
20" 1680 x 1050 is 16:9  or to put another way 7.11:4 or 5.33:3
                         (33% wider than 4:3 / 42% wider than 5:4)
