Hi, I have a question about lens shift. According to the LG Calculator, the lower edge of the image is flush with the lens, i.e. already shifted upwards even without lens shift. Is this the "zero" value and does one still have the 60% leeway from there? I ask because I would like to place the projector next to the sofa and make full use of the 24% horizontal lens shift. Does this also mean that it would be an advantage if the lower edge of the image is already at lens height and I lose horizontal by a vertical lens shift correction (as far as I know, I can't go to both extremes)? As an alternative, I am looking at the Epson TW7100, but the image is centred, i.e. the centre of the image corresponds to the centre of the lens. Thank you very much!
