Arcada's all rooms have DisplayPort (DP) and HDMI connection to the projector/TV.
Use the adapter that is attached to the HDMI cable if needed. If you do not have DP nor HDMI out on your laptop, please bring your own HDMI-adapter with you. This is the case e.g. with all Apple products.
Usually the picture is automatically transfered to the projector when you connect the cable, if not, press the Windows-button + P (=project) and choose e.g. Duplicate. Duplicate means you will have the same exact picture on your laptop screen as on the projector.
