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

I have been using this monitor for many months, working from home on different platforms. Works great out of the box for Windows and Linux. The text is a bit small, but very clear at 100%. I prefer to work at 125% to protect my eyes a bit. Text appears 100% small on a Mac. Mac does not scale like Windows and Linux. If instead you want the text to be larger or smaller, the Mac simply changes the resolution, which makes the text look blurry. To get around this I had to install the SwitchResX app and add a new HDPI resolution of 1920x1080. This made the text large and clear. So if you're planning on using this for a Mac, make sure you're also running an app that lets you add supported permissions.
