Why do I need VTBook if my notebook already has a video output?
• VTBook has 32 MB memory dedicated to one video output, this means it can offer higher and deeper (more colorful) resolution for your external display while still benefitting from hardware acceleration. See the resolution table for more details. • VTBook offers a full digital DVI display connector, as well as the traditional VGA connector. • VTBook natively supports a huge range of displays and resolutions and, on Mac OS, can dinamically recognize even more resolutions reading from the display. • VTBook supports special displays like Apple ADC displays or portrait (pivotable) LCD displays. • On older notebooks VTBook is faster than the internal video output. • With VTBook you can add one more external display to your notebook and, if your notebook already has a video output, reach the total of three displays.
