The cable coming into your home has many channels of video modulated on RF
carriers at different frequencies.  The box the cable company gives you
selects one of these many carrier frequencies (e.g. channel 13) and
effectively removes the video/audio information from it and places it on a new
carrier and sends that out to your TV set (typically channel 2 or 3).  The TV
set's tuner removes the video and audio from the carrier and then sends the
video to the "monitor" section of the TV.

Your monitor doesn't have a tuner section so it can't decode the information coming
in from the cable.  This is one reason why the cable has an F-plug and the
monitor has an RCA plug.  Note:  you'd have the same problem if you connect
the cable to the VIDEO IN jack on your VCR.

Try running the cable to the CABLE or ANTENNA jack on your VCR then connect
your VCR to your monitor.
