Video projection

Wireless video projection

The video projectors in the meeting rooms of the CPHT (Louis-Michel in building 6 and Bocal in wing 0) and the CMLS are equipped with a wireless video projection device Airtame.

Step 1

Switch on the video projector (select the HDMI-1 source if necessary).


The photo of the Ecole Polytechnique seen from the lake must appear, with the connection information to the WIFI network of the amphitheater or the meeting room.


Step 2

Connect to the wireless network associated with the video projector using the password (updated daily) displayed on the screen.


When opening the window asking for the WIFI password on MAC OS X, uncheck the default option Memorize this network. If the WIFI network has already been memorized in the past, it is possible that there are difficulties in connecting to the network, the password having changed. To solve this problem, open the Keychain Access, Password tab, identify the WIFI network and delete it.


Step 3

Download Airtame Client if not already installed.


The app lets you cast your presentation window or your entire desktop. This feature is not present in Apple's AirPlay and Google's Chromecast protocols where only the entire desktop is projected.

Step 4

Connect to the projector via the Airtame application installed on your laptop.

PowerPoint, Google Slides) in private on your own computer screen and your presentation slides on the Airtame-equipped video projector screen. Learn more about How to use Presenter mode.
