I have turned LS10000 on and off over the past few months while I have been building a dedicated home theatre room, and even just projecting onto the grey concrete wall the picture quality impressed me. Now projecting in a room where the walls are a shade lighter then black (wanted black, wife said no) the picture is absolutely amazing I couldn’t fault it. For the first time that I can remember I have sat down and watched movies without complaining about some aspect of the picture quality not being up to theatre quality. Even when calibrating the projector the settings out of the box were near perfect. Once you get the settings right on the 4k enhancement the picture is mind blowing for Blu-rays. I am very keen to try actual 4k content to see how it preforms. Epson, you have one very happy customer right here.
