All my LCD's have all been IPS except a few old laptops. That being said it is funny to me that the *only* other LCD's I have seen have this same retention issue has been my IBM T221 9503-DGP and my Viewsonic VP2290b which are both QWUXGA (3840x2400) ultra high DPI (204 PPI) monitors like the retina macbooks.
Just thought it was interesting...
