Ok, I chose another cheaper model, HD143X with 3000 lumens and Full HD resolution. This HD28HDR model is very different, HDR and "4K ready" are of great importance. Colors are way better, this one is 3600 lumens, 4K isn't true 4k of course, but it's not Full HD either, it's somewhere in between, I mean you'll see the difference forever! 4k is a luxury I can't afford in my case (a 4k projector costs $1,000 or more) but this projector is a very good middle ground between something really expensive and something very good. 100% recommended. The lamp is very cheap in exchange, 12000 hours life, good brightness, very low noise. The speaker is very simple, almost weak, but you don't buy a projector because of the speaker's performance, do you? In summary, this is a good choice for demanding users on an average budget. You will not be disappointed.
