Hi all, My new Optoma UHD35 just arrived. I have a mid 2015 15" Macbook pro as my video source and a Pioneer VSX-921. My plan was to run an HDMI 2.0 cable from my Mac to the Pioneer and a second HDMI 2.0 cable from the Pioneer to the Optoma. (This is what I did till now with my old 1080P Optoma). I anticipate a few problems and would really appreciate some guidance. Can my Mac's HDMI port output 4K 60Hz? I'm pretty sure its specs indicate only 30Hz. If not, can I achieve this by connecting an active mini displayport to HDMI 2.0 adapter? I read somewhere that this is possible. If not, is there another option? Assuming I can output 4K 60Hz from my Mac, can my Pioneer pass it through to the Optoma? According to its manual I think it's saying that the max it can handle is 1080p. It has a PURE setting that supposedly passes the signal through, but I still don't understand if it can pass through 4K. If I can output 4K 60Hz from the Mac but cannot send the video through the Pioneer to the Optoma, is there another option? Is there some sort of switch or splitter that I could buy that could input the HDMI 2.0 from the Mac and then have one HDMI 2.0 go from the splitter to the Pioneer for audio and a second HDMI 2.0 go from the splitter to the Optoma for 4K 60Hz video? I really appreciate any advice you might have!
