When IBM didn't like the panels they could source for Thinkpads, they started a new company called International Display Technology to manufacture panels they did like. Thinkpads used to be special.

While it's entirely possible there's a connection between decisions like that and IBM's PC division being unprofitable enough they sold it to Lenovo, it might be reasonable to hope that Lenovo would make the effort to offer competitive panels when it's obviously possible for their competitors to source them.
