VIM3 mesondisplay.cfg file

Hello
I need to change framebuffer to 3840x2160

vim3 source code /device/khadas/kvim3/files/mesondisplay.cfg file
has display config.
MID gxl 1080p I will change to -> MID gxl 4k2kp

is it right?

and gxl is vim3 driver?
top line comment write meson3 | meson6 ~ meson8m2 <-- what is this
