I just recently setup a Yamaha RX-V577 in my bedroom. The output of the receiver is connected to the HDMI port of my monitor. I was wondering whether there is a way to turn off HDMI output off from the receiver's menu or remote? The reason is that I normally leave my monitor in standby mode and never turn the power off. When I want to listen to radio in the dark before going to sleep, the monitor's backlight will be on as if the receiver is outputting something but the monitor is blank (I turned display off on the receiver). I would like to turn off the HDMI output so that the monitor will not detect any input and go to standby and the backlight won't be on lighting up the room. Is something like this possible?
