Most lecture rooms in buildings 1, 2 and 6 are equipped with video projectors mounted in the ceiling, with loudspeakers on the wall. There are projectors also in a few conference rooms.
To use the projector, press the "PC" button on the control panel next to the blackboard, and connect your computer using the cables (power, video and audio) available at the lecturer's desk. Then start your computer, letting it automatically detect the video parameters of the projector.
If the "PC" indicator is already lit, but the projector lamp is off, then the projector has timed out due to lack of video signal. The panel will reset itself after a few hours, but in order to use the projector immediately, press the "OFF" button, wait for the panel to stop blinking, and then press "PC" again.

All projector models have a native resolution of 1024 x 768 pixels.
Most rooms are equipped with this projector model.
The combined computer lab and lecture room 1412 has two projectors and corresponding display screens.
Rooms 1211 and 2146 are equipped with this projector model.
In order to reduce wear on the delicate floor connectors and simplify user access, cables (power and video, as well as computer network and audio where available) have been permanently installed at the lecturer's desk. Use the cables you need, but never disconnect them in the floor connector end, as the video cables have been chosen to match the projector specifications.
Connecting computers to projectors
The stationary and portable projectors available are of different models and age. Connecting various computers to them and getting an acceptable picture can thus sometimes be a bit of a challenge. Here are some hints towards making it work.
In general, while the projectors can deal with a wide range of display parameters, they work best when provided with a video signal matching their native resolution, which is 1024 x 768 pixels.
- By default, some Apple Macintosh models and operating system versions, including the Apple MacBook Pro laptop available for borrowing, treat the internal display and external projectors as two independent devices, showing different parts of your desktop. To have the picture on the internal display be sent also to the projector, go to System Preferences -> Hardware -> Displays -> Arrangement and mark the Mirror Displays option.
