The projector will scale it and use its 4k-like technology to make it look as 4k as possible. Epson calls this 4K Enhancement. Projector central says: The key to understanding why the 4K Enhancement looks so impressive is realizing that there's only so much detail the human eye can actually resolve. The 5040UB's pixel-shifting technology increases the apparent resolution of the picture by enough to come close to that limit. Of course it depends on how close you like to sit to the screen. And it also depends on the type of subject matter -- it is easier to see resolution differences between the 5040UB and native 4K projectors when viewing high resolution graphics and text documents than it is with video.
Sorry, there was a problem. Please try again later.If it is like my Epson projector, it won't work at all in less than six months. At that point you will not only be unable to view 4K from your Roku, you won't be able to view anything on it.
Sorry, there was a problem. Please try again later.Yes, I use a Roku with 4K, and it works great for me. When I am in the Netflix app, it will display which shows are capable of streaming 4K content by having a small 4K/UHD icon.
