Inadequate quality of displays in "new" Lenovo ThinkPads (post T60) is well-known problem. The Lenovo tabook.pdf file http://www.lenovo.com/psref/pdf/tabook.pdf specifies contrast ratio 250:1 for X201 12" WXGA models (page 149).
Recent NotebookCheck review http://www.notebookcheck.com/Test-Lenovo-ThinkPad-X201-Notebook.33616.0.html has revealed real measured contrast ratio 126:1 only.
Yes, customers can tolerate few percent difference here and there but this is almost half of the specified value only.
