Hardware: amd radeon rx 5700 and two monitors.
Current Release: 2020.11.01
After choosing the boot menu "Arch Linux install medium (x86_64, UEFI)" the signal disappears from the monitors (no signal). If you connect a second monitor after booting, then everything is correct.
The same thing after installing the OS, it does not boot from two monitors, only one. If you connect a second monitor after loading, then everything is ok.

On Ubuntu 20.04, loading with two monitors works.
This task depends upon

@Depher: Thanks for the report.

I believe this is related to which version of the kernel is used on the installation medium, which is not a specific attribute of the archiso project.
Please open a ticket towards the [linux] package or report this issue upstream to the kernel mailing lists.
