I have the monitor and S27C450B been going on for 2 months in use and am always happy about the excellent print results. The TN display is simply unbeatable for Office applications. I had a direct comparison to a PLS display S24C650MW, I have given due to its rather transparent-looking typeface back.
For gamers and video viewer a TN display mM would be to not as good as PLS displays but for office work the monitor is perfect, no shiny surfaces that could refect, super image, suitable height adjustment and pivot function for me as a CAD user also very good and fast to use.
