| Is the coax cable coming from the wall? If YES, then this isn't going to work. If NO, the coax is coming from a cable tuner box, then it SHOULD work already.
Remember that all TVs sold noawadays are "cable ready" meaning the cable tuner is already built into the TV. An LCD monitor will not have this circuitry, so the cable from the wall will need to go through a cable box to turn the signal into something usable. |
