Does using lens shift on the ae700 affect the picture quality at all. my mate got his 700 today and i went round to help set it up. After id installed all the latest graphics drivers and 1:1 pixel mapped it i notiiced that it didnt look anywhere near as sharp as my ae500, i have a 5'7" across screen with the projector ceiling mounted at a distance of about 9 foot, my mate has a 6"6" across screen with the projector at a distance of about 13'. The focus seems to be off from about halfway down to the bottom and in the top right corner of the screen, you can easily see this by dragging an icon around the desktop and watching it go in and out of focus, the projector is mounted in line with the top of the screen and then lens shift used to bring the image down. Would the increased screen size and distance plus use of lens shift affect the picture so dramaticaly.
