Hi, Trying to get my head around the throw calculations of the HS20. Nothing on projectorcentral yet, but the pdf literature suggests "Standard Lens Thowing Distance" 40" 1.5m-1.8m; 60" - 2.3-2.8m ; 80" 3.1 - 3.7m ; 100" 3.9-4.6m etc up to 300" 12m-14m Are these likely to be widths or diagonals ? I notice screen size is quoted as 40" - 300" so I guess whatever this is measures is the answer. Planning on getting a 203cm wide screen (seems a fairly standard width) and this equates to 80". Or a 173cm screen if these are diagonals. Could potentially place the pj at over 4m away, but would be offset a metre or so. Hmmmm. Ta.
