A:Answer Being able to use your own screen and not a bundle is nice, but beyond that, it has quite a bit of tech. The L9G is great, but the PX1 Pro is better As long as you control room lighting pretty decently. Not a bright room winner. Designed for a true theater style experience. With the PX1’s new focus features you can fine detail perfect clarity edge to edge. Best I’ve seen in any projector and have tried them all. The ability to enable 120hz 4k is also a big separator, especially if you game.
