I am considering a Yamaha TSR-7850 however I wanted to see if anyone knows if it will work for my setup. Downstairs I have a media room with a 1080 projector and 7.1 surround. Upstairs I want to get a 4K LED with Dolby Vision HDR and a soundbar. The signal source will be a Dish Hopper 4 which will be located downstairs and directly connected to the Yamaha receiver. I would use HDMI Out 1 to connect the 1080 projector. I would connect the HDMI 2 out to a 4K HDMI ethernet extender that would send a signal to the upstairs 4K TV. I would never need to have the downstairs and upstairs on at the same time. However, I don’t want to go downstairs and turn on the receiver every time I want to watch something upstairs. Does anyone know if the Yamaha receiver will passthrough a 4K signal when the receiver is turned off? Or if any other receiver would be able to accomplish this? Thanks
