As far as I remember it would be 3 separate channels and 3 separate DLP chips. Modulation will be done by DLPs themselves the same way it's done nowdays. Second I don't think this will be cheap. Something around 20K. Then beam specs will be horrible because they have to cover a large 1cm or more DLP matrix. Plus the life of those TVs will be no more then a year or so. Then there are many laser projection regulations in the world. For example I think in Finland maximum allowed power is 100mw 3 meters above people's heads. I personally think this laser TV will be a complete flop!
I hired an Italian guy to do my wires. Now they look like spaghetti!
