Match the screen, lens and room. Check the stated throw ratio, lens setup and connections. ANSI, ISO, LED and centre-lumen claims keep their different measurement bases; they are not an overall picture-quality score. A projected 4K claim does not by itself identify the physical imager pixel grid. Accepted input modes remain separate.
27 verified differences, most decision-relevant first. 7 are also drawn in Visual facts above. Missing information stays separate.
