It's starting to look like this is a Plymouth bug/feature where it
applies the same resolution to all monitors:

https://gitlab.freedesktop.org/plymouth/plymouth/-/issues/119
https://gitlab.freedesktop.org/plymouth/plymouth/-/issues/9

If true then that would make sense. Plymouth uses software rendering and
possibly can't afford to render multiple monitors separately.

Title:
  Vendor logo does not display in correct ratio on external monitor as
  it have different ratio than internal on

Status in OEM Priority Project:
  Confirmed
Status in plymouth package in Ubuntu:
  Incomplete

Bug description:
  As Ubuntu boots up, the vendor logo will be retrieved and displayed on
  the monitor.

  Per test, as internal and external monitors have different Wide/Hight
  ratios, Plymouth will use the monitor ratio of the internal monitor,
  and the vendor logo will be displayed on both monitors.

  Some laptops can boot up even as it's the lid is close, and use the
  external monitor, keyboard, and mouse only.

  For that case:

  - internal monitor: off
  - external monitor: display the vendor still in the internal monitor ratio.

  Which is ok but not perfect.
