I just received my raspberry pi 4 and I've got a basic setup ready to go. However when I turn the Pi on nothing displays on screen. I've got a microSD with Raspberry Pi OS installed already.
Here's some info:
- Green light blinks erratically, with no discernable pattern, occasionally stays on for some time, then eventually turns off
- My portable monitor runs on Mini (not micro) HDMI
- I've reformatted the microSD using a formatting software
Would like to hear some possible solutions. thank you!
