I am considering upgrading to the 5050 - I currently have a 4-year-old Sony VPL-40ES that I would retire. Nothing wrong with the latter, just older technology.
My receiver is the Marantz SR7008, advertised as "1080P and 4K Ultra HD Pass Through". Not exactly sure that that means. It is 1.4a HDMI.
Does the fact that my receiver is 1.4a HDMI mean I am going to have issues passing the blu-ray and/or 4k video signal through from my HTPC and/or 4k blu-ray player to the 5050? Given that the 5050 is 2.0 HDMI, how will my older receiver's 1.4a HDMI work with it?
I guess I'm confused about the different HDMI ratings, and how they impact video signals. Am I better off bypassing the SR7008 and running the video direct from the player to the 5050?
Also, my current HDMI cable in the ceiling is 2.0 HDMI, so I think I'm good with that? Or do I need to run a new HDMI cable to the 5050 as well?
Thanks for helping me understand all this...
There are two standards that get discussed, HDMI and HDCP.
HDMI will refer to speed/bandwidth.
HDCP will refer to copy protection and passing high definition signals.
HDMI 2.0 and HDCP 2.2 have been mainstream for awhile now. You need HDCP 2.2 to pass 4k signals. Everything in your chain would need to be HDCP 2.2, AV Receiver, Blue-Ray Player, TV/Projector to pass the signal.
HDMI 2.1 is just starting to appear in newly released equipment. HDMI 2.1 will incorporate HDCP 2.3 which will allow for 8k+ video to pass.
I would make sure your current cable is marked "High Speed" in order for it to pass 4k but if I was spending money on new projector/equipment, I would also throw a new cabe up in the ceiling.
Google HDMI cable specifications, there is some good information on the new marketing terms and a certification process that is being used to help consumers know they are getting a certified cable.
