Hello.... I was using nanodlp an older version that don't have the 3D AAA so, I decided to update my nanodlp to last version. After the installation the LCD doesn't work anymore. The lines are offset from the border or sometimes the lines appear completely mess. How can I do to fix it? I want to continue with this release because of 3D AAA....
My LCD is ls055r1sx03
Raspberry Pi 3B+
Nanodlp 4271
I was using this config before the update: (this config doesn´t work with new update)
