Angående diskussionen om var displayport kommer ifrån och vem som har utvecklat det:
DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). The interface is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to carry audio, USB, and other forms of data.[2]
The VESA specification is royalty-free. VESA designed it to replace VGA, DVI, and FPD-Link. Backward compatibility to VGA and DVI by using active adapters, enables users to use DisplayPort fitted video sources without replacing existing display devices.
