Preview the video output port
You can preview the video signal that is shared over your video output port by looking at the preview window
at the bottom of the video output configuration page in the Admin panel.
The preview is updated every few seconds and always maintains the same aspect ratio as the
source it is copying. It doesn't reflect black bars, the audio meter or actual aspect ratio/resolution
on the display.
