The most common formats are 16:10, 16:9, 4:3 and 1:1, the figures represent the width of the screen in relation to its height. We advise you to have the same format on the screen as the projector’s standard format (the panel).
16:9 is the format the new TV sets and DVDs are using
16:10 is the format for business projectors.
4:3 is the “old” TV format that also works with computer programs as for example PowerPoint.
1:1 is a format used with OH-projectors, some computer programs and it is often installed in conference rooms.
