OpenLDI graphic cards
Once upon a time, in a galaxy far away the first digital flat panel (DFP) displays where digitally connected not by DVI, butOpen LDI: a high-bandwidth digital-video interface standard for connecting graphics/video processors to flat panel LCD monitors. It was based on the FPD-Link specification, which was the standard for transferring graphics and video data through notebook hinges since the late 1990s. Both OpenLDI and FPD-Link use low-voltage differential signaling (LVDS) as the physical layer. The SGI 1600SW was the only monitor produced in significant quantities with an OpenLDI connection (though it had minor differences from the final published standards):
While there where not many display, there were a couple of non-Sgi PC graphic cards that included OpenLDI:
- #9 Revolution IV-FP
- 3Dlabs Oxygen VX1-1600SW
