It's a setting within Denon. Look for something re primary power. I have the little guy X2400h. Regardless if I use cable remote, TV remote, or Denons app. Receiver powered down, when tv is turn off. You can also wake the tv from each of the source on the receiver remote or tv remote. If your Q series came with the minimalist remote that can control everything. You would have to create an applet on the for the receiver. HTH
