Elegoo screen not displaying

I'm using an ELEGOO 5.5 inch 2K LCD for Mars 3D printer and Ls055r1sx04 2k LCD SCREEN HDMI mipi Driver Controller. The screen is functional but only displays when the calibration tests are run manually. Even then, the displayed image only covers four rectangles like a window on the right side of the screen (~30% of total area). It doesn't display anything when a print is running. Do I need to change something in the machine settings? Thanks for any help

Re: Elegoo screen not displaying

Hi! I switched to the same display and controller a while ago and this config.txt kinda works for me:

hdmi_pixel_encoding=2
gpu_mem=128
framebuffer_width=1440
framebuffer_height=2560
max_framebuffer_width=1440
max_framebuffer_height=2560
hdmi_force_hotplug=1
hdmi_cvt=1440 2560 30 3
hdmi_group=2
hdmi_mode=87
hdmi_drive=2
config_hdmi_boost=4
hdmi_ignore_edid=0xa5000080
