Ok, this is the second thread (
here's the first) in which someone has insisted that current MBPs use IPS panels.
I know my 1st gen 17" doesn't (but it's old), and
this detailed article on laptop screens claims that a relatively recent generation was also TN, but I can't find any definitive answers one way or the other on the current MBPs, and I don't have a nearby Apple Store to check in person.
Not saying anybody is wrong, just that I can't find a definitive "This is an IPS panel" source to cite (though I admit find it a little odd, given how much Apple has emphasized the iPad and iMac and 24" LED screens all being IPS, that Apple doesn't advertise it anywhere).
To Jethryn Freyman and others who say that they're IPS screens, are you saying this because you own one and can see that it has the 178° viewing angle and off-angle behavior of an IPS screen, or do you have another source you're using for the info? If so, please post the source so I can refer others who think they're TN.
