I'm interested in a 4k portable monitor which is 14" in size.
I believe it is mainly intended for use with iOS/Android, however it does say supports mac/win.
The concern I have is that even at the familiar maximum 2x scaling, which we call retina resolution, 14" at "looks like" 1920x1080 will result in very small ui. To compound the problem in this case, this display is touch, too; which is likely to make finger accuracy an issue.
Does or can mac os support greater than 2x retina? How are the supported resolutions for a display defined? Is this something apple does, or does the manufacturer do it; can a user adjust it without going too low level?
