HDMI CEC should be able to to turn on TVs direct to the input. Sadly few desktops seem to support it.

Apparently "almost no PC GPU has hardware support for CEC" according to Arch. Wonder if that is outdated and modern GPUs do?

		This is still pretty much the case. There are ways to do it (i.e. adapters that sit between your HDMI cable and GPU) but it’s wonky.

The Steam Machine will support CEC, hopefully other PC vendors will take note and adopt it.
