First Things First
Many HDTV owners don’t know that high definition picture requires a high definition feed. Plugging a regular cable or satellite box into a new HD set cannot guarantee a high definition picture. There may be a need to contact the cable or satellite provider to request for an HD set-top box or satellite subscribers may have to upgrade their dishes. Signing up for an HD subscription plan as well may be in order.
An HDTV that has a built-in HD tuner can pull down HD signals with a good, properly aligned rooftop antenna but most units would require the purchase of a separate high-definition tuner box to go with in. There are still shows that are produced in standard definition which HDTV cannot magically convert to HD.
