So I've been trying to troubleshoot this for a few days now with no success. I'll try to keep this short and to the point. here it goes:
Got the desktop kit, loaded up noobs, installed raspian full desktop. goes to 100%, restarts (rainbow, 4 raspberries) then no video out of HDMI 0 or 1. green light flashes until then, then it goes away when the video does.
Tried a different card. Tried reformatting and just downloading straight raspian buster on there. tried the bootloader (worked) then retry everything again to same result. tried different monitor (lg tv and aoc monitor). Tried editing the config file to remove the hashtags on the few hdmi lines and changing the one value from 4 to 9.
I'm using macOS catalina 10.15 for everything. (wouldn't be surprised if thats somehow the problem.)
I'm clearly missing something stupid here. I've tried hunting the forum and internet for something worded similarly to this but can't seem to find it. Not trying to spam the forum.
Any help or links to a fix would be greatly appreciated.
