You can check the parameter table of the projector, if the projector has a throw ratio range instead of a fxed throw ratio, then the projector has adjustable throw ratio.
Throw ratio is the ratio of Throw Distance to the Screen Width. The bigger the Throw Ratio value, and the farther the distance required for the projector to project the same screen size.
For example, projector A has a thow ratio range of 0.8-1.4, then the projector has a changeable throw, and the projector B has a throw ratio of 1.2, then the projector B has a fixed throw.
