So I just got a Raspberry Pi Zero and an SD card with NOOBS pre-installed. I placed the SD card onto the RPi as well as a keyboard and a power supply. I plugged the RPi onto two different monitors, however there was no video output (HDMI) on both. I tried cycling through pressing 1-4 on my keyboard, however nothing worked.
There is a constant green LED flashing, apparently this means there is some sort of error on boot up? I'm very new to all of this, what would you guys recommend that I do?
