Something I`ve noticed is that the image quality on my screen seems to have improved after a few day's use. I'm sure that's due to my eyes becoming accustomed to the new TN panel after using IPS for a couple of years.
Yes, you will notice that. There is always an adjustment period when using a new monitor with some different image characteristics to your previous one. If you were to now use a decent IPS panel you would likely find it quite different once more. The sort of weaknesses and differences there are highlighted quite nicely in this forum, for example - with the weakening saturation lower down the screen for the blue background colour. Far more consistent on IPS models and something you'd initially notice quite clearly when first moving to the TN model.
