But sometimes, the laptop may fail to identify the projector or fail to download the correct driver for it (along with the correct video settings), it will just use what was previously set (which may be out of range). In this case, all the user needs to do is manually change the video settings to the lowest resolution initially (640x480*60Hz) and step up from there.
Exactly. At worst, the laptop just cannot detect the video resolution of the projector or vice versa. All that is needed to be done is to set the laptop and projector to 800x600 and manually shift up to the desired higher resolution.

Not really a compatibility issue.
