correct eye position (beamer)

hi guys,

i have a standard setup of a cockpit and a big straight screen-wall infront with a beamer on top showing FSX.
If the screen is far away, the view is normal. but now i have moved the screen near to the cockpit to give it a
more real look, it seems to me, that the view is not correct anymore. e.g. during landing or while taxiing, it gives the
feeling not to be on centerline flying at the cpt left seat position. the copilot side right seat - view seems to be fine.

what can i do to fix the eye position to have a correct view from left seat ? do i have to turn the beamer some degrees or
make some adjustments in the software ?
