You need a higher quality cable for the higher pixel clock rates of 4k, so that is possibly the issue.I then changed resolution to 1280 (Raspberry symbol top left/preferences/screen configuration/layout/screens/noop-1/resolution.)
I then plugged back into my monitor. (my monitor wasn't accepting the default pi at 4k)
All worked .....
