Those who are going to try the EZCOO won't be sorry. I've posted several time in other threads, and maybe this one, that you can follow an opposite version of GIGO(Garbage in Garbage out). I call it FIFO; not First in First out, but Finest in Finest out. If you take a high resolution source, finest, and do a good job of reducing it to a lower resolution, then you will get a better image. So there are two factors entering into the equation. One is the quality of the 4K. Was it original like on a UHD BR disk, a UHD video by the streaming hosts, Netflix, Prime, etc., or a 1080P upscaled by the streaming device. So the 4K quality of the input is important, Secondly, how well does the EZCOO do when downscaling. To my eyes it's great. Of course, as we on this thread know, we are using the best projectors to take advantage of this situation.
