Here is another probably stupid question for the helpful folks on this forum: I have a new LG 55UF7600, a new Samsung BD -J7500 and a new Denon Receiver AVR-S710W. I have the Bluray and cable box connected via HDMI to the receiver and then the receiver to the TV via HDMI. The TV and the Bluray both upscale to 4K but the receiver does not. If the TV upscales everything to 4K do I need to receiver to also - since everything is connected to the receiver? If so - I guess I need a different receiver. I am hoping that the fact that the TV upscales solves the problem but I don't know enough to know. Thanks for any help anyone can give me.
