5. Use a Hex converter like http://www.mathsisfun.com/binary-decimal-hexadecimal-converter.html enter your width 5760 = 1680 now flip the bits so = 80 16 if you get a number like 567 it would = 67 05
6. enter that value right behind 8th column filling column 9 an 10
7. do the same for the height on row 8930 but you enter you hex value flipped on the 3rd column filling column 3 and 4, again look at my pic
