what is even the point of it?
No one’s been on this spacecraft design while it’s in space before, and it’s got some kinks that need to be worked out (like the issues with the toilet); it’s a shakedown flight to figure out what goes wrong when people are actually on board. That’s not really all that sexy compared to a moon landing, but testing your support systems in practice really needs to happen before you do more ambitious things with the craft.

I’d expect almost any computer/gaming monitor on e.g. Amazon around the $100~$150 (US) price range would meet or exceed your needs.
Edit: e.g. here’s a glossy 27" for $99 and a matte version from a different brand for $159 (with some cheaper used options). I have an older monitor similar to the latter (from ~10 years ago). Finding ones that explicitly list “pivot” functionality for the stand is the trickier part of searching for these.
