Are you guys able to elaborate further on this?
Based on my own understanding (I'm a noob in this subject), I am guessing that you guys mean that the F270i pro uses an AHVA/PLS panel compared to IPS (as the monitors don't look like TN panels and the specs don't suggest that it is a VA panel).
If that is true, based on what I've read, technically that is true that they're not real IPS, as the name "IPS" is a trademarked term for panels made by LG/Sharp. However, according to my knowledge, IPS and AHVA are quite similar and IPS is more commonly used as an umbrella term to refer to these group of panels (AHVA, IPS, PLS) which have the same adv/disadv to IPS panels. In that case, while the F270i might not actually be a true IPS panel, for most people, it does not matter as much since the IPS here is just a "name" and the differences between a real IPS and AHVA/PLS panel are small compared to VA or TN.
Maybe there are some differences between true IPS and IPS-like panels like colour accuracy, longevity, etc since they are made by different manufacturers but I am not informed enough about these.
Also, apart from the price, are there any telltale signs that led you guys to think that it might not be true IPS? Just here to learn.
