I have just purchased an Acer UHD 4k2k monitor. When used at full resolution, Photoshop desktop toolbars, icons etc. are very small. I can only get things back to normal by reducing the screen resolution, which defeats the purpose of buying the monitor. Any ideas as to how I can enlarge things?
You can set the UI scaling in PS CC, but not in older versions.
Many thanks Mylenium
That works a treat! I did not look in the experimental section of preferences, I would have thought it would be in the interface section.
