Question about upgrading projector and reciever in basement to 4k
I am ready to to upgrade my projector in my basement to 4K. I currently have the BenQ W1070 with a home theater in the box Onkyo 5.1 DTS surround system with all of the speakers mounted professionally. I set it up with all of this about 6 years ago when we finished our basement.
If I am going to upgrade to a new 4K projector, do I need to upgrade at the very least the reciever as well? I ask this because I currently have the HDMI from my Nvidia Shield and Bluray player going through the Onkyo reciever as pass through video. The problem is I do not believe my Onkyo reciever is compatible with 4K. I believe it to be too old of a model and I thought I read online that if you are using your reciever as a pass thru for 4K video you need to have a reciever that is compatible with 4k? Also, if this is true, would I need to upgrade my speakers too? Aren't the receivers that handle 4k typically ones made for Dolby Atmos? I don't think my standard 5.1 speaker set up is compatible with Atmost? Am I wrong?
Also, is there any way around this so that I only need to get a new projector and that is it? Or if I want to watch 4K on my screen with the full surround experience, do I need to route the 4K video through the reciever?
Any help would be much appreciated.
