If it's particular to LG and not VGA generica, email jorsher at good old g mail and ask him if he has access to such. He works for LG and runs through a pile of used/return monitors.
SCL SDA ST? Sounds like some kind of serial bus. The important connections for a VGA monitor and Hsync Vsync R G and B data lines and their associated grounds, the rest don't belong to the VGA standard.
