WOW. Okay, been stuck on this for months and when nothing worked, the latest stable update that included nvidia 550 → 570 just got displays working!
No change to any config, didn’t need modeset=1, etc. Just works like magic.
@JPS you might want to try updating.
@soundofthunder sorry missed replying to your message. I don’t know about wlr-randr, but as of now, xrandr shows HDMI for me:
