1DLP lenses offer a lot of flexibility for different projection projects. Being able to adjust both vertical and horizontal offset through a motorized interface seems like a convenient feature for precise positioning. And the ability to save lens positions to projector memory for future use is a nice touch for consistency across multiple setups.For specific lens throw distance formulas, it's great that you provide resources like the Christie Projector Lens Calculator or the lens throw distance ratio PDF. These tools can be invaluable for ensuring accurate projection setups tailored to each individual project's needs.
