Right now I'm using a 1600 x 900 20" external monitor with my rMBP 13" (2014). The actual size of the monitor and text size is *perfect* for me. But after getting used to the fantastic retina screen on my MacBook Pro, the low resolution of the monitor is like a dagger in my eyes. I know there are plenty of high resolution monitors that are 24" and larger, but I want to stick to 20". Can anyone recommend a 20" monitor with higher resolution that would maintain the text size as is on this 20" 1600 x 900 monitor? Thank you in advance!
