Could someone please clarify which throw distance calculator is most accurate - the one on projectorpoint.co.uk or projectorcentral.com.
I have tried both of these for the Hitachi PJTX100. I have set both for a throw distance of 10.5'. The comparisons are as follows;
projectorpoint - min zoom = 55" screen width, max zoom = 69" screen width.
projectorcentral - min zoom = 61" screen width, max zoom = 98" screen width.
If you go back to Projector Point you'll see that apart from the throw calculator you can also download Hitachi's own brochure as a PDF file. On the last page it gives a table of throw distances. From that you should be able to work out which one was telling the truth.
