I've been recently reading about monitor calibration and there are a lot of information available on the web that may lead one the be confused. As it seems to be my case. After reading some sources, I've narrowed my options down to Spyder 4 Express and x-rite Colormunki Smile as they seem to be more in accordance with my monitor pricetag (a DELL P2214H - equipped with an AH-IPS panel). So I'd like to know if anyone here could have an opinion about the performance of these two calibrators compared to each other. Or even a third option that could be more feasible.
