Two different review mags are showing two different NEC models for the 231. EA231WMi and EA231WMi-BK. The BK is supposed to have a TN panel and the EA231WMI has a e-ips panel. Can someone tell me which monitor has the e-ips panel?
I can't really answer it because I don't really understand what are you referring to, but I can assure you that with the title that you gave to this post, the chances of getting an educated, and high-level answer is low.
I would recommend you to erase this question, and post it again under a different title. As a proof, you posted this question on Thursday and not only that there isn't any answer, only 23 people have watched it.
