I have the same question. Anyone who knows the answer, please give us a hint on how to enable it either in bios or system os. I really appreciate your help.
I searched for a long time, luckily I found this.
You must update your BIOS to 0031 or the settings won't work correctly. I haven't been able to find a suitable mode for it yet on my LCD (Samsung LTN154AT01) but at least I get a picture! This document was for some project called the G11, an AIO computer, so be sure to set your LVDS screen mode and the single/dual channel setting as well!
Hope that helps!
You may also want to update to BIOS release AG0040 (or later) as it has LVDS enabled by default.
