I bought a U2412Mb monitor (IPS panel) earlier this year in March 2015. A few weeks ago the monitor suddenly had a vertical purple line appear out of the blue. So I called Dell support and they shipped me a replacement monitor, model U2412Mc. I can't find any official information from Dell on this, but I believe this U2412Mc is a TN panel (from what some sites describe this monitor as). I paid for a IPS panel. What is Dell trying to do here, by trying to do a switch on me? Is this U2412Mc model really a TN panel?
