> Black on a projector is still projected light, especially with a DLP which have the worst contrast ratios of the 3 projector types (DLP, LCD, LCoS). If DLP has worst contrast than LCD, then why would this project be even remotely successful? Wouldn't the LCD layer in the stock LCD TV would have already been more effectively blocking the light from the stock backlight?

    No and there are monitors that do that (search dual layer lcd monitor). They are really expensive.
