Hello, I have a 27" 5K inch Imac (2017) and I am considering an Apple Cinema Display as a second monitor. I need to know from those of you guys who have the same setup how does the text look on the Cinema Display. Is the difference in screen resolution annoying? I am a translator and work only with text and translation software and I am very happy with the resolution of the 5K iMac. Thought about buying a 21.5" iMac as a second monitor, but not sure if this would work. Any recommendations regarding the model of the Cinema Display? Or other external, not so expensive, matte monitors? My ideal setup would be to have 2 other small monitors. Thank you all so much in advance!
