NUC (windows 10) is connected to 4K LG TV and i have to modify the aspect ratio in intel graphics setting (3840x2160) in order for the display to fit the display.
why is it not done automatically?
You should have a setting on HDMI for Picture size on the TV that says"bit by bit" or "just scan" or something like that. If 16:9 does not fit properly. also set 16:9 in the graphics settings
Sorry for the late response.
Yes i have updated nuc to the latest firmware and drivers (via Intel® Driver & Support Assistant).
