Review on Dell U2520DR UltraSharp DisplayPort Certified QHD Monitor - Crystal Clear 2560x1440 Resolution by Matt Rostamian

Just the right size, very good colors, factory calibrated, 2K is good enough for most applications and users. 4K is overkill unless you're looking at the monitor from a few inches away and using a magnifying glass. Very happy with the quality and functionality for the price. It also doubles as a USB hub to connect to your Macbook with a single cable with USB-C connectors. And the icing on the cake - 3 year guarantee!
