Only Moorestown should be using the other style of data and Moorestown never became a real product. However if the panel is on the SDVO port then the BIOS data would appear to be correct as it isn't on the LVDS channel but bridged off the SDVO. In that case it'll need SDVO support sorting out. Alan
