A number of electronic classrooms at the University of Toronto have received significant upgrades.
Some rooms have X-terminals.
You can also have the computer's video output displayed through a video projector for all in the class to see. You press an on-screen icon to select the item you want to use or adjust. For example, there may be a control for a slide projector, but you will have to make arrangements with local building support staff or the Office of Space Management to have the slide projector brought to the room and connected at the required time. Or, there may be a slide projector permanently mounted in a booth, but you will have to make arrangements to get access to it. Read the documentation which accompanies each electronic classroom.
