tty/tuigreet/greetd configuration on multi-monitor setup

Hi guys!
I have some problems with proper tuigreet/greetd configuration on my setup (4k laptop + external 1920x1200 monitor, intel GPU and nvidia GPU with proprietary driver, early KMS enabled).

1. tty size isn't scaled on the laptop screen, so I get normal size full-screen login window on the external monitor, but it's very small on the laptop. It happens only if the external monitor is attached - if I don't attach it, tty scales perfectly on the laptop screen. Is it actually possible to have different tty scaling on different screens?
2. The login window is polluted with systemd boot log. I've seen the relevant issue on tuigreet (https://github.com/apognu/tuigreet/issues/17) and on greetd repositories (https://todo.sr.ht/~kennylevinsen/greetd/26), and it seems for me that disabling "wall" logging in journald together with "vt = 2" in greetd/config.toml should fix the issue, but it doesn't. Changing greetd service type from "simple" to "idle" doesn't help as well.
The issue doesn't occurs when the external monitor isn't attached. Is it a greetd/tuigreet bug or it's just a misconfiguration from my side?
