It often appears looking like your output is scaled , in the instance below you would get the top left 1920x1080 pixels over the whole 3840x2160 you are sending. In the case of SDI output modules you will get no output.

To check to see if your display is doing this in windows display settings select the display you want to check then scroll down to the Advanced Display menu and select it

If you then navigate back to advanced display settings, you should find the Desktop mode and Active signal Mode match
