I can run 4K DSR on my Optoma GT1080.. it looks blurry, but it works. I'm considering getting a 4k monitor that I will be cloning to the projector. I'm curious as to whether or not I'll be able to clone the monitor without having to run games at 1080p. Would setting my native resolution to 4k on the monitor upscale to 4k DSR on my projector, or would I have to disable the projector and game solely on the monitor in order to play at 4k?
