    I know keystone adjustments do, just wondered if the horrizontal and vertical shifts will lessen the picture quality?

    They do have an effect and it can vary from pj to pj. In some cases it can exacerbate chromatic aberration, alter center to edge focus or reduce contrast and light output. In most cases you probably won't notice the reduction unless the CA is very pronounced or the focus is noticeably blurry. Try it and see if you notice any reduction in image quality. If you do, try to find the optimal position for the lens and then place the pj accordingly.

    Thanks.
    I couldnt see any difference. I have sky HD feeding my Panny AE500. Each feed to the pj seems to have a different picture position. Fed up with moving the pj bracket slightly everytime!
