Via the suggestion box, Dominic Self asks why screen resolution is a global setting rather than a per-user setting. Well, first of all, it’s not even a global setting. It’s a session setting.
That it’s not a global setting is not readily apparent most of the time since only Windows Terminal Server is set up to support multiple simultaneous interactive sessions. On Windows Terminal Server, you specify the properties of the virtual monitor you wish to connect with, including resolution, and the server accommodates your wishes. Well, up to a point. I mean if you ask for a 1,000,000×1,000,000 pixel screen, the server is probably going to say “As if!” (The Remote Desktop Connection feature found in, for example, Windows Vista Ultimate is basically the same thing, but on a smaller scale.)
