One Nit

I read with interest the piece, "Video Wall New Concept for the Future," in the January 1989 issue of American Cinematographer.

However, there is one nit I would like to pick. Near the end it is stated, "A video wall can already deliver 2100 lines of resolution in the 4x4 array" (Writer's note: 4x4 monitors, and also, incidentally: 4x4 pixels) "because each monitor is capable of 525 lines of resolution."

The way the video wall works is that it replicates each video pixel in an array equal in size to the monitor array. Therefore there is no increase in resolution in the displayed picture, although it looks great in the large size. (You can't invent new pixels that weren't there before!)

Again, I say this is a nit. Anna Alworthy, the film student who produced the video, deserves a lot of credit for the many innovations she brought to the production.
