With locked down I mean if you don't have root access on your own device. Since it's running Linux, you _should_ have root access and thus be able to control everything. So you should be able to use a mini hdmi adapter and use [`xrandr`](https://wiki.archlinux.org/title/xrandr) or other programs to output something on your external monitor.

However, I never used Umbrel so don't know how they setup the system. Not entirely sure how it will work but I am 100% sure there is a way.

What's your opinion on Umbrel?

What do you mean by a locked down system? Do I just buy a mini hdmi to regular hdmi and plug it into a monitor to see if anything appears?
