 <note tip>A good starting point is 1280x1024. In most cases this will delivery a quality picture. Depending on the projector, you may be able to achieve even better results with higher resolutions.</​note>​ <note tip>A good starting point is 1280x1024.

 +====== Recognizing the Projector ======
 +
 +Projector Mode is indicated by the fact that after you have successfully logged in, both display devices (Monitor and Projector) display the same picture and additionally the existence of a pop-up menu on the bottom edge of the screen.
 +
 +So that the Minilinux can activate the correct display mode, all attached display devices (more specifically,​ the EDID information that they register) will be probed. A projector will be correctly identified and switched to the proper mode in the following cases:
 +  * Display width is 0cm //or//
 +  * Display width is greater than 90cm //or//
 +  * Display width is greater than 70cm AND the display width of the second device is less than 55cm

 +
 +In some cases the projector cannot be automatically identified. In this case you will see the vmChooser on one device and the other device will simply show the bwLehrpool background image. This is often due to an in-line switch box that manipulates the EDID information. Usually these switches can be specially configured, solving this problem. ​
 +
 +If this isn't possible, the display device can be explicitly defined as a projector via the web interface of the satellite server. This setting will than override the automatic detection and always treat the device as a projector.
 +
 +In the web interface, browse to '​Client-Statistiken'​ and choose the client attached to the projector. The right column displays the information regarding the hardware discovery, including the attached display devices. For example, in the image to the right the device 'EPSON PJ' has been designated as a projector ('​Beamer'​). This setting will be globally set for all clients, so that all devices with this name will now be identified as projectors.
