I have recently got my first Raspberry Pi. It is a Pi 0 (without wifi). I installed NOOBS (version 2.9.0) onto my PC, then copied it across to my SD Card(formatted using the SD association formatter) where I extracted the files. Once this was done, I popped it into the Raspberry Pi. I plugged the HDMI into a monitor but no signal was recognised. I have not plugged in an ethernet as of yet. I have also tried donwloading LIBREELEC to my SD, but that shows no input too. Have I done something wrong?
What does "I installed NOOBS onto my PC" mean? You CAN NOT installed NOOBS on a PC. Is there any reason you DID NOT follow the instructions on the Foundation site?
NOTE you will need at least a 16GB SD Card for Raspbian and LIBREELEC.
Personally I wouldn't use NOOBS but PINN - which is functionally similar, but more efficient and flexible.
