I just got a new Raspberry Pi 4 and a blank 16GB MicroSD card. I downloaded NOOBS v3.1.1 and put it on the SD card, then put it in the Pi and plugged in the power. At first, nothing showed up on the screen, but I was able to fix that by creating a config.txt file and adding the line hdmi_edid_file=1.
After that, I was able to see something on the screen, and I installed Raspbian. When Raspbian finished installing, I got a message that the OS had successfully installed, and I hit Ok expecting it to reboot. However, after I hit Ok, the screen went blank and there is no HDMI signal.
I've seen a lot of forums that suggest uncommenting and adding lines to the config.txt in the GUI before installing Raspbian, but nothing I've tried has worked.
If anyone has any idea what the problem could be, please let me know!
Thanks in advance,
