I don't pretend that I have the best vision out there, though I don't think I'm completely blind since I don't run into things. But I actually measured this display, and it's within specs. So maybe both I and my colorimeter are blind? Sure, it's not absolutely impossible, but how likely is it?

I actually have a newer "ips black" dell, an ultrasharp 3223qe and yes, it's much better.

But what I'm saying is that the old one is still good. However, I never pretended it was as good as current models. That's moving goalposts. The initial comment was about the display degrading, so comparing it to itself when new (not even other similar models from that era!). Mine only seems to have become somewhat dimmer, but not enough to matter in my day-to-day use since it's still brighter than I need.
