Notebook Computers And Resolution Standards NEC projectors are designed to project industry standardized video such as VESA (Video Electronics Standards Association) or VGA (Video Graphics Array). Notebook computers do not use industry standards. They use whatever timing is necessary to match their local LCD display. The end result is typically not standards. By turning off your notebook's display, the timing parameters are a bit more like the real VESA or VGA signal. For an optimal projected image with a notebook computer, it is recommended that you use the Auto mode. This feature is useful when an XGA image ( ) is displaying with a notebook computer supported by SXGA ( ) and when an SVGA image ( ) is displaying with a note book computer supported by XGA ( ).
