Raspberry Pi Forums

I made my friend some Pi Zero slide show players for his store. They work great except a power up problem. All the monitors and Pi's are turned on in the morning by flipping a single breaker. It looks like the Pi's are starting up faster than the monitors and when this happens I get no output from the Pi's until I power cycle them. I'm using Raspbian Pixel from 9-23.

Any thoughts on how to solve this?

Add boot_delay=<seconds> to /boot/cmdline.txt (Remember that cmdline.txt must be a single line)
