Yes, it will if the monitor has been told to display the signal as 16:9. Remember that a monitor can’t actually tell if the signal is meant to by displayed 4:3 or 16:9. You have to tell it (assuming the monitor can do both). There is no “flag” or marker in the video itself. The change from 4:3 to 16:9 happens only at the display. The question is whether the image in the signal is meant to be displayed as is, or to be stretched out to 16:9.
This gets a bit trickier with file-based playback, dvd, or dtv broadcast because these formats do have a variety of flags and parameters that control playback, but a simple NTSC analog video signal only comes in one form.

P.S. One warning. I’m not as familiar with PAL as I am NTSC. I believe the two are the same in this particular regard, but I might be wrong.
