Connecting a 4 channels LVDS LCD (without EDID) to a 3 channels motherboard

<< < (4/4)

Berni:
Well there are two standard LVDS signaling formats called VESA or JEIDA. Both have the extra color LSBs on the 4th channel, but have the other bits jumbled up, but its perfectly possible there are displays out there that use some proprietary LVDS bit format. This format is one of the things that the BIOS needs to tell the graphics card, and i don't think this is part of the EDID since the interfaces that is was designed for such as DVI HDMI..etc have the bit mapping format defined by the standard so it is always the same.

The last industrial motherboard with LVDS video output that i have used had the LVDS output formats and resolutions configurable inside the BIOS settings (And also could not support any arbitrary weird format and resolution combination, it had to be something standard from the list).
