Each technology has its pros and cons. The faux 4K methods whichever you choose has cons versus a true 4K. To keep it simple whenever you are displaying multiple pictures to show one frame of video there is going to be a problem. That problem often shows up in motion artifacts especially when showing video with a lot of movement or fast panning of the camera. We specialize in projectors and do more than 200 installs a year, about 80% commercial and 20% home theater/ media rooms. The JVC NZ-3 would be a good choice as well as the Epson if you need more light output than the native 4K projectors. It will be a little louder in high lamp mode and you will need to use dynamic mode and cut the green and blue with the JVC. The JVC and Epson's next lower modes are about 2200 lumens and only about 600 more than the JVC NX-5.
