Renoise unfortunately can not switch between Retina and non Retina resolutions dynamically at the moment when multiple monitors are present, so it will use the main monitor’s as base resolution and then lets OSX up or downscale the UI on the other screens.

So if you make your external 4k monitor the “main screen” (the one with the dock), it should work for now.
