Beginners • How to NOT use attached monitor resolution in WayVNC?

I set up a new Pi5 at a remote location and plugged it into an old DVI monitor + kbd + mouse in case anyone needs watch the boot process. Now that I'm away, RealVNC Viewer (on Windows 10) only allows me to connect at the 1280x1024 resolution of the monitor attached to the Pi, rather than the 1920x1080 resolution of my local monitor. How can I fix this?

I've tried:

1. In /boot/firmware/config.txt, set display_auto_detect=0 -> this just gives me a blank screen when connecting VNC
2. In ~/.config/wayfire.ini, added \[output:headless-1\] section with headless_width|height values
3. In ~/.config/wayfire.ini, added \[output:headless-2\] section with mode = 1920x1080
4. Tried restarting wayvnc specifying --output=headless-1|2 but first it complained that WAYLAND_DISPLAY was not set in the environment
5. So I tried setting the variable with export WAYLAND_DISPLAY=headless-1 (and also headless=2) but then I get...

   ERROR: ../src/main.c: 529: Failed to connect to WAYLAND_DISPLAY="headless-1"
   ERROR: ../src/main.c: 530: Ensure wayland is running with that display name
   ERROR: ../src/main.c: 1876: Failed to initialise wayland

6. I noticed at some point (maybe after display_auto_detect=0 was set) raspi-config gave me the option to select VNC resolution, but once connected, I was still stuck at 1280x1024

I'm at a loss. What do I need to do to have BOTH a working display on the Pi-attached monitor AND a higher resolution display for VNC connections?

In case it matters, wlr-randr returns:

I'm at the point where I'm ready to try a different VNC client or just switch back to X11, but I'd rather get familiar with Wayland.
