DISPLAY, the environment variable that says 'Hey, remote host, this is where you need to send your fancy graphics!'

I think it's DISPLAY because it tells the remote host where to display the graphical interface.

DISPLAY, hands down. Without it, your remote X11 apps would be flying blind.

$DISPLAY, of course! How else would the remote application know where to display its GUI?

That's right, without $DISPLAY, the remote application wouldn't know where to display its GUI.

DISPLAY is the obvious answer. When X11 forwarding is enabled, the remote host needs to know where to send the graphical output.
