There is this new crop of LCD monitors that have these wider screen size than the traditional screens. I suppose they are designed for better enjoyment of watching movies. I have seen resolutions on these LCDs like 1440 x 900 and 1680 x 1050. If you divide one number into the other, then the ratio is 1.6 (1440/900). However, when I go into some of the resolution options for some video cards the ratio is 1.7. Why is there this discrepancy?
