The growth of three-dimensional visualizations and information is increasing over time, and in addition to that, technology is offering new methods, i.e. models and ways of meeting the needs of visual communication. When using the rotating linear screen, for the best results, it is necessary to be familiar with the real performance of the device. The parameters tested on forty examinees are distance, the angle of view and the impact of the background colour. The purpose was to define the optimal parameters for the device to provide visual information. The conducted test has shown that the devices have a smaller view angle than stated and that the distance needs to be greater because of low resolution and low pixel density on the screen surface, which results in small unilluminated gaps that create unwanted lines during the projection. The effect that the background has on the 3D simulation of the hologram has also been tested and it was determined that the black background in comparison to the white one is much better, as the contrast is more pronounced.
