What happens to the CPU/video card when the monitor energy saves?

I've got an iMac TFT.

When the energy saver kills my monitor, I can no longer take screen captures with SnapperHead Server, for example. They just come up blank.

Does this mean that the CPU/video card stops processing the UI entirely!?

I'm currently on 10.1.5
