Broke my Pi 3B+ HELP !!

[Kb8srx]

Hey guys, I just got my Pi 3 B+ setup with raspbian desktop and had it working just fine, but I changed the screen resolution (I think) to make things on desktop smaller, and then it rebooted, upon reboot, monitor now just flashes "INPUT NOT SUPPORTED".......and nothing I do (I admit, Newb to linux here) will get me back into the Pi, I can go through SSH from my windows computer, but I can find nothing on how to change it back, I just got FlightAware up and transmitting data, so I really dont want to reformat and re-install.......IS THIS FIXABLE ? help a newbie out please

What happens if you ssh into the pi, use raspi-config to go to Advanced options then set screen resolution to say 1024 x 768 ?

Easy. You can try to fix it via ssh, but an easier option is to undo what you did using another computer.

• Shutdown your Pi, then remove its sd card.
• Insert the sd card into a sd card reader, then stick that into a PC (or another Pi).
• Find config.txt, and edit it using Notepad or an equivalent text editor.
• For every line that mentions "hdmi", comment it out (add a # at the beginning of the line)
• save, close, eject, remove, insert into the Pi, and turn it on.

Hope that helps.

Not sure how all that faffing about is easier than -

sudo nano /boot/config.txt
