7 Things You Should Know About Video Walls — from library.educause.edu /

Excerpt:

What is it?
A video wall is a large-scale ultra-resolution digital display that joins multiple display screens with minimal bezels to create what is essentially one large screen. While the multiple monitors can be tiled to display one large image, the technology also lends itself well to viewing multiple sources at one time. Video walls are linked via software to a computer or other media source. Video walls typically are arrayed as flat-screen planar displays; sometimes the walls are curved. Found in public spaces like stadiums and airports, video walls are increasingly used in higher education as tools for pedagogy and research. Sizes vary. One example consists of 24 HD displays tiled and connected to create a 50-million-pixel screen. Another example combines twelve 55-inch ultra-resolution LED screens. A video wall at Stanford University measures 16 x 9 feet while one at Georgia State University measures 24 feet wide.

What are the implications for teaching and learning?
Video walls help create a dynamic, interactive, hands-on educational environment that enhances research, encourages active learning, and bolsters collaboration between faculty and students. Used for visualization and modeling of large data sets, for example, this technology helps learners and researchers view in-put with different perspectives, helping them draw new conclusions and deeper analyses, and contributing to the development of new knowledge. Through that capacity, coupled with the immersive experience created by large-scale displays, video walls help learners bridge quantitative and qualitative methods, inter-disciplinary exploration, and diverse modes of inquiry to address complex questions across the arts and sciences.
