I have the same issue with my HTPC, using a brand new Pioneer receiver (and the same with a older Marantz). Switching either of those receivers in standby is probably similar to just pulling out the hdmi-plug.

In the Xorg.0.log I see this, when I turn a receiver off:
(II) NVIDIA(0): Setting mode "NULL"

And when the receiver is turned back on again, I see the normal report of its EDID information.

I have another workaround to switch it back on again, since I use x11vnc, I have access to my display server via the network. Using nvidia-settings I can see under "X Server Display Configuration" it has switched the "Resolution" to off. Switching that back to Auto or 1920x1080 also re-enables my screen.

When I do that, I see this in the Xorg.0.log:
(II) NVIDIA(0): Setting mode "DPY-1:1920x1080+0+0"

It'd be nice if it did that automatically when the screen is turned on again.
