recently got an x220i 4290HP1 model instead of stolen 4290LB4.
found out the screen to show very poor view angles. Yes it's certainly IPS as there is no color shift or inversion like with TN, but the brightness is dimming greatly withing 5-10 degrees range!
actually, it is causing eyestrain even when looking straight at 90 degrees.
i will attach a video shortly - can you check and tell if my screen is just OK or if i should seek for replacement?
thanks in advance!

Yes, the model is supposed to have "Premium" IPS panel according http://support.lenovo.com/en_US/product-and-parts/
The Premium panel is actually e-IPS which is not full IPS (like desktop S-IPS, P-IPS) panel, if you are comparing it side-by-side with x-IPS desktop monitor. I also notice small changes in brightness but it is still far better than any TN panel.
