Wanted to ask the following but there was always a server error 500....

Does anyone have the same problem of not being able to focus the image properly everywhere? Primarily left or right sharp but both together only moderately "sharp" possible. This is even worse in the corners.
I have the beamer upside down. At the bottom of the picture with lens shift approx. 2/3 downwards (from the beamer in upright position it would be towards the top) the bright icons/font even have a glow towards the outside. With min. lens shift (image towards the centre of the lens) this is better. With focus too, but then it is totally blurred on the other side.

In addition, when I switch to "dynamic" mode, the picture or the lamp is as bright as Bright, for example, when I have vlc open maximised without video (black).
