Optoma UHZ50
Very good projector with an exceptional 4k image, I don't regret my purchase at all.
The reason I didn't give it 5 stars is that it doesn't support the 60hz mode natively without turning the fan all the way up, so it's extremely noisy and annoying when the film has a low soundtrack.
The remedy is to set it to 1080i, 1080p or 4K => 50hz and not 60hz and everything is fine.
