The screen surface is made of a proprietary write/erase projection film that is permanently adhered to tempered hardboard, allowing you to use dry erase markers and interactive styluses. The screen comes with a package set of markers, eraser, and cleaner.

The 71842 is available in three formats: HDTV (16:9), Wide (16:10), and Markerboard. The HDTV format is ideal for watching movies and TV shows, while the Wide format is better suited for presentations and spreadsheets.
