Please try replacing the entries you put into “/boot/userconfig.txt” with

hdmi_group=2
hdmi_mode=87
hdmi_timings=480 0 30 30 30 1920 0 6 6 6 0 0 0 60 0 66000000 7
hdmi_drive=1
framebuffer_width=1920
framebuffer_height=480
max_framebuffer_width=1920
max_framebuffer_height=1920

To rotate the display you should be able using “Orientation Settings” on the Touch Display plugin’s config page.

Please try with

hdmi_timings=480 0 88 44 148 1920 0 4 5 36 0 0 0 60 0 89000000 7

Possibly in front of it you might also have to add

hdmi_ignore_edid=0xa5000080
