IT WORKS! I just came back here after googling for how to show both video and waveform in the source window. I didn't find an answer at the time, but today after plugging in an hdmi display as a 2nd monitor to my laptop that after I enabled it in the Premiere > Preference > Playback that when i left the source monitor set on waveform, the external htmi display shows the video at the same time! very helpful! I still agree it should be an option to show them both on the same display pane, but at least it's possible! It's also very nice to have a full monitor output switch between the source and timeline automatically.
