I need a larger monitor for my Graphic Design work and after lot of research realized that it is best to go for an IPS panel. But I am really confused between these two models. Dell U2715H is expensive but is WQHD (2560x1440) whereas HP 27 CW is only FHD (1920x1080) and is 12-15K cheaper. Does WQHD provide any significant benefits over FHD at this size apart from more real estate? Dell model also comes color calibrated whereas HP will need adjustments at home. Please do advise. I have been struggling with this decision for quite some time now.
