We offer them as a standard part of our resident (dedicated) desks, which is our top tier membership. Every resident desk has one. If a resident member doesn't want one, we remove it. They are the standard, free-standing monitors (though a well known local biotech giant has 4 desks at our space, and they mounted 4 of those ultra-wide wraparound monitors at each of their desks on one of those hydraulic arm things, hella slick). However, each resident member is free to bring in their own monitor if they prefer, for whatever reason.
We have a few extras in case one of our open space members (''hot desk'') wants to use one, though we don't actively publicize that. Though they are also welcome to bring in their own and store it on our premises. We also have a few meeting rooms here and sometimes we get a request for a desktop monitor instead of the wall-mounted monitors we have in each meeting room, so they come in handy for that too.
This is simply what we do, not gospel by any means.
