(In color) Out of the box you won't find anything. For lower resolutions check out 'JumboTron' made by Sony for sports stadiums. I saw a display once (back when hi-res color was very expensive) which consisted of four crts, mounted in a rack side by side, in a 2 X 2 array. The crts had fresnel(sp?) lenses in front of them to magnify the screens such that they abutted each other. Using a 13" screen (which is actually n x n where n ~ 13/1.4 ~ 9") and 1K x 1K resolution. An array of 13 by 13 monitors would be (13/1.41)*13/12 ~ 119 inches ~ 10'. At a distance of twenty feet you could probably ignore the edge effects of the crts. Crude yes, and you would need 169 frame buffers (assuming 24 bits/pixel) thats 507 megs of frame store (maybe you could use it as a ram disk when the monitors were off ?) A somewhat more practical approach would be to use lasers rather than crts. Modulate a laser in much the same way as a crt and use three of them to scan the screen (R, G, B). In either case you are talking big bucks here. --Chuck McManis uucp: {anywhere}!sun!cmcmanis BIX: cmcmanis ARPAnet: cmcmanis@sun.com These opinions are my own and no one elses, but you knew that didn't you.
