Screen (Portal 2)
Monitors are easy to make and they make the map more living.
Step 1: Entities
Step 2: Point Camera
Make a point_camera with the name monitor_camera. It should look like this when you put it in your map. Make sure it is in the right position so the monitor will show up clearly the Wheatley in the func_monitor
Step 3: Monitors' Properties
Go to the func_monitor’s properties and set camera name to: monitor_camera.
Step 4: Triggers
Connect the camera and the monitor to a trigger and set the trigger’s output to:
Step 5: Texture
Texture the face you want the screen to appear to "dev_tvmonitor1a". You should also click the button "Fit" for a better quality.

Of course you need to trigger the logic_choreographed_scene. For example:
