The displays resolution is 1080p at 60Hz I have changed config.txt. And yes my display is HDMI. It also shows the diagnostic screen without the SD card.
Almost certainly a 'display or monitor' issue, not directly attributable to the RPi4. On the diagnostic screen, what does the line tagged "display:", about 12 lines down, say?
