Troubleshooting • Re: Problem with Johnwill Monitor

I've inserted :

video=HDMI-A-1:1360x768M@60D
video=HDMI-A-2:1360x768M@60D

at both the beginning and end of cmdline.txt.

Now I get a black screen with white text saying :

Running /scripts/local-premount ... done
device specified. Boot arguments must include a root= parameter.

v1.35.0 (Debian 1:135.0-4+b3) built-in shell (ash)
help' for a list of built-in commands.

mfs)



I suspect I might be losing the odd character off the lefthand edge of the screen.

Please help before I throw the Pi400 through the closed window.
