That's exactly what I use it for... but I run the output to my 4K LED, instead of a projector. I wouldn't see why there would be any difference what video display you use. Plus, it works better to use the 4K pass through with this reciever... now I don't have any audio/video syncing issues, as I did with having the audio and video going through my TV separately(via optical cable and HDMI). Now both are fed through the reciever with one HDMI input to output.
