As I was looking to overcome wake-time speed and lower power consumption, a commenter pointed me to USB powered monitors. This could work but I doubt the Pi Zero can power a device like this.
I wanted to wire in the monitor's power button to another set of pins but was also thinking of HDMI-CEC should the monitor I will be using support this.
I'm open to suggestion on what type of display device would best suit my needs. And if the Pi Zero would be powerful enough to power a USB monitor, and if there is driver support for this kind of stuff.
