I've a UHD display connected to MAC via HDMI. But the external display is not rendering in native resolution.
There does not appear to be an option in preferences to set to native resolution of monitor ?
With SwitchResX preferences I can display in native resolution of 1440x2560, this software is not free. This option should be available on osx ? Option clicking for more resolutions does not display the resolution of my monitor of 1440x2560.
