I upgraded from a MacBook Pro with a good quality LG 4K 27” display using non integer scaling to a 5k 27” iMac with 2x scaling. Both provide the same visible screen area and not give you the same size icons and text. But the iMac with integer scaling is a better, sharper picture. The difference isn’t huge but it’s noticeable.
I am talking about good quality display with bearable price. Not display for $6,299.00 Example: https://www.amazon.de/EV3285-BK-Monitor-DisplayPort-Reaktion...
