Click on the link below for a summary of the differences between the H9G and H8G series. Below the link is an informal comparison I did myself. The features shown are for the H9G but, wherever there are differences for the H8G - I show them in parentheses. The features and specs are pretty close but, the peak brightness and dimming zones are much better on the H9G. I plan on buying the 65H9G tomorrow from Best Buy.
