The Adafruit 5" display backpack works well with the RPI-4B. Here are some configuration tips. NOOBS/Lakka/Raspbian all use the same settings for boot (see here)

• NOOBS: In Raspbian, mount partition mmcblk0p1 and create a file config.txt in it that contains the lines below
• Lakka: In Raspbian, edit the file /media/pi/System/config.txt and add the lines below
• Raspbian: Edit the file /boot/config.txt and add the lines below (see docs (here)[https://www.raspberrypi.org/documentation/configuration/config-txt/])

hdmi_group:0=2
hdmi_mode:0=87
hdmi_cvt:0=800 480 60 6 0 0 0
hdmi_drive:0=1

• uncomment these lines in /boot/config.txt

framebuffer_width=1280
framebuffer_height=720
