Friend of mine wants to buy a projector and asked me for recommendations, but I know hardly anything about them. His budget is £250 for both projector and screen, and distance between the two will be roughly 4/5m. Screen size will be roughly 60" and needs to be ceiling mounted. Main use will be with a Chromecast, so ideally it needs a USB port for power. He also wishes to connect to his sound system as well, and already has a 3.5mm audio cable running from it. Not too fussed on quality, he seems happy with 720p, is it possible for a decent projector and screen at this budget?
