I have some shitty koorui (bottom left) and an intehill one that I quite like (top right of the photo) (kudos to nostr:nprofile1qy88wumn8ghj7mn0wvhxcmmv9uq3xamnwvaz7tmsw4e8qmr9wpskwtn9wvhsqgxezxg7xrsqg39egtqwst9dgu9n9tchzajvyf6mac9anymhal2qw5fup4qy for hooking me up)

depending on your preference of how you want to position it (stick it to the side of the laptop vs free standing placement) you might want to look into something more elaborate like sotsu or bunch of others who are doing similar things. there also lots of dual options now.

i havent bit the bullet on any of the expensive options yet - I have some cheap amazon portable stands and duct tape for improvisation

also for longer stays I've also bought a cheap monitor before and donated it when leaving
