I have a 2K Dell UltraSharp U2717D sort of pushed into getting. My reluctance was, I knew there was going to be an issue with fonts being small. I knew someone who has a 4K had the too small front. Unfortunately I cannot reach her to find out how she fixed it. I believe it can be fixed I don't know how. When I bring in Adobe that it is a problem. There is a custom scaling, my concern was the warning that if I did use custom that some text, apps, and other items to be unreadable if a display doesn't support that size. It might be hard to go back to original settings. It says not recommended. Looking for people who have dealt with this what was their workaround.
