Can I change the screen resolution?

It is possible to change the screen settings, but it is not something we have had a chance to simplify or automate yet. If you change the display settings like you normally would in Windows, you may get disconnected and then be presented with a screen that has a login button on it. Click that and it should reconnect you to your same running session (90% of the time) with the standard 15 second countdown already in progress. Just click ok to keep your settings for that session.
