That's it guys, I have built an ultimate budget home cinema.
GM60 1000 lm LED projector from Gearbest.com is great for watching movies, tv shows, etc. You can plug your PC, Android TV box, Chromecast or anything you want through built in HDMI port. However it's noisy, too dim to view in daytime and resolution is only 800x480, so it's uncomfortable to read very small text.
For the price I am happy to recommend for anyone who doesn't want to spend too much on a projector.
