Hello, just bought an MBP 2017 13". When I turned it on, the letters are very very small. How do you guys/girls use it? Manually increasing the font size? So inconvenience. (It seems that once I have disconnected the MBP from the 4K display, letters became larger. When I connected it to the 4K display again, letters became very very small to the point of unreadable. Is this normal? What is happening?) Anyway, I connected it to a HP 32" 4K display. https://store.hp.com/CanadaStore/Merch/Product.aspx?id=K3Q96AA&opt=ABA&sel=MTO I went to Pages and opened the "Modern letter" sample. I had to increase the font size manually to 200% in order to see the letters well. 300% is very comfortable. I guess the optimal percentage is 200%-250%. Under Safari, I had to zoom in two times to see the letters on CNN webpages. Zooming the page three times make it very comfortably to see the words. All viewing from arm's distance of about 62cm. Based on this information, what 4K monitor/TV size do you recommend? Thanks.
