I don't think the comment you're replying to claims that LG was the only manufacturer of displays, just that it has manufactured displays badged with other brands (and perhaps still does) and recently started selling them under its own name (perhaps as well, rather than instead).

LG does manufactures portable hard drives and has a partnership with Hitachi to manufacture internal hds. ( http://www.engadget.com/2008/07/21/lg-reveals-xd1-family-of-... )

Here is a list of Dell displays with their respective manufacturers, including LG/Philips ( http://en.wikipedia.org/wiki/Dell_monitors )
