Product placement
(a) HY300 projector: ACTS; it is shown projecting video content onto a wall, and its features (built-in apps, speaker, connectivity, resolution) are listed as text overlays. Removing it would change the entire video. (b) YouTube, Netflix, Chrome: APPEAR; these are logos or names of services accessible via the projector's interface. Removing them would not change the video's focus on the projector itself.
