I had a similar problem with my LG Monitor and PIR-Sensor.
In my case i had the following behavior:
Using HDMI Connection: switching off was possible, wake up
not
Using VGA Connection (with HDMI->VGA adapter on RPI side): switching off an wake up was possible
Details see post.
No worry using HDMI->VGA adapter: VGA can also deliver FullHD Resolution.
Maybe your problem could be solved with an adapter.
