Actually, the lines are drawn horizontally. Interlaced video draws the 1,3,5,7,... lines first, and then draws 2,4,6,8,....

Those are dynamic contrast ratios and they are absolutely useless. The real contrast ratio of most sets is around 800:1 to 1000:1. The real contrast ratio is the ratio of brightness of white to black when displayed simultaneously.
However, LCD sets can make the backlight brighter or darker depending on what is on the screen. Dynamic contrast ratio is the ratio of white with the backlight on at full to the TV off (black with no backlight).
Dynamic contrast ratios are meaningless because they are comparing two images measured at different times. I can take any TV set and mount a searchlight in the back and that will give you a dynamic contrast ratio of trillions to 1, but it won't improve the image quality one bit.
Thankfully, the real contrast ratio, which the TV and monitor manufacturers rarely advertise, is mostly the same across sets, so it's not that important a number to worry about. You might be able to tell the difference between 800:1 and 1000:1, but it won't be that noticeable.
My advice: don't worry about contrast ratio.
