I want to use pi-hole and it comes highly recommended to use raspberry pi to cover the house and have an always on capability. I started looking at just starter packages at Amazon and they don’t come with a monitor, which it looks like you need. How do I do this? I want a raspberry pi to run pi-hole to protect my house.
Edit: Thank you all so much for the tips and all the different ways to get this up and going , I am officially on my pi-hole journey!
Rasperry PIs have micro-HDMI outputs, so you can use those (with an appropriate cable/adapter) to hook the PI to any monitor (or to your TV) for the initial setup (you’ll also need a keyboard and - possibly - a mouse). After that, you can unplug everything and use the raspberry pi without keyboard/monitor/mouse (pi hole has a web interface).
Note that you don’t strictly need a raspberry pi to run pi hole: any old x86 PC or a cheap thin client bought on ebay will do just as well (actually, they will most probably perform better).
Only the Pi 4 has micro HDMI outputs. The other ones (except the zero) have regular HDMI.
