Troubleshooting • [rpi5] [AlpineLinux] How to force HDMI Console-Only Resolution?

1) I have successfully got Alpine Linux (a minimal, GUI-less by default, Linux distro) working on my rpi5, using the following instructions:
https://wiki.alpinelinux.org/wiki/Raspberry_Pi

2) Even though it is not directly pertinent to this discussion, I have successfully configured this machine to allow SSH access, using the following instructions:
https://github.com/macmpi/alpine-linux- ... -bootstrap

3) I am now trying, unsuccessfully, to change the Resolution for the physical Monitor that is hooked up to my rpi5 via HDMI:
3a) I have altered both config.txt and usercfg.txt with the "hdmi_mode" and "hdmi_group" parameters, using the following instructions:
https://elinux.org/RPiconfig#Video_mode_options
3b) I have altered both cmdline.txt and /boot/config-rpi with the "video=" parameter, using the following instructions:
https://github.com/raspberrypi/document ... ution.adoc
3c) I have attempted to set framebuffer_width and framebuffer_height in config.txt using the following suggestion from this forum:
viewtopic.php?t=284528
3d) I have attempted to use setfont as described in the following forum thread:
https://www.reddit.com/r/AlpineLinux/co ... t/gurt2m4/

4) Everything I have tried has no apparent effect on the Display Resolution, to a hardware monitor, on boot, nor does the TTY output indicate that there is any specific error or problem with the things I changed. (Even an Error would be helpful but nothing I have done has any effect at all.)

Any tips on how to Change the Command Line Resolution are greatly appreciated! --rs
