I replace the previous model, the Epson Home cinema 3700. I have to say this is worth the upgrade. Its basically the same projector outwardly but with a few hardware and software upgrades. The 3800 has better contrast at 100,000.1. The 3700 was 40,000.1 The 3800 accepts the full 4k uhd HDR10 @60z and accepts the full 18gps, the 3700 was only 1080p. This is a better projector for watching 4k movie and for gaming.
Picture is very clear. I have an awesome pioneer elite receiver and projector did not work at first. I had to turn 4K upscaler off on the receiver to get it to work.
