This is just guess but does your monitor have an mhl hdmi socket on it?
I've had power issues with my monitor while connected to a pi. The monitor has an mhl hdmi socket which supplies power as well as receives hdmi signals. When connected to that socket I couldn't reset the PI by pulling the power lead. The mhl hdmi socket was back-feeding enough to keep the power led on regardless of the PI's actual power supply. I had to unplug the monitor as well as the power to reset it.
The monitor has two hdmi port and now I just use the non-mhl hdmi socket for the PI and it works perfectly.
