The answer is there is no limit. The best projectors for home theatre have always had one important advantage: size. Now, thanks to some nice technological developments and 4K streaming, that size is being used even more effectively. If a 50-inch television can't always tell the difference between 1080p and 4K, a 100-inch screen will. For those who are having trouble visualising it, that is roughly the same width as Shaquille O'Neal is tall. It's enormous. And it's magnificent. Another significant advantage is that if you purchase a pulldown screen, you will not have to keep a large black box in your living room at all times. You now have the best of both worlds: a massive screen when you're watching a movie, and one of those cool living rooms with no television when you're not. As a result, it will feel like you are experiencing the most desired and best home theater you ever needed.
