We didn't go too in depth on either, but both off vivid, to standard, and the motionflow was turned off. The sony style folks apparently aren't supposed to set this one up till Monday, they brought it on a wheeled cart and pulled it underneath the xbr. The brightness on the Z was spectacular, it just didn't have the level of richness I was looking for. The Sony folks said something about not using as large a percentage of the color wheel, apparently xbr4/5 used 95% whereas the Z uses like 75%. Obviously, I have no docs to back this up.
