DLP660TE: How to achieve 9000 lumens of brightness with the help of DLP

Hello

       Referring to the TI white paper, if I want to achieve 600 nits effect in a 120-inch screen, I need 9000 lumens of brightness, which corresponds to a 0.9-inch DMD. However, the largest DMD size on TI's official website is only 0.66 inches. Is the 0.9-inch DMD achieved through several 0.66-inch DMD cascade? If so, how can I get the cascading components? If not, do I need to design by myself? 

Thank you in advance for the anticipated favor.
