Looking at your Tuner Options
The type of HDTV you have or wish to buy will determine the type of tuner you will need. For instance, if you have an HD monitor, be aware that these types of electronics have no built-in HDTV tuner of any kind.
Meaning, you will need to buy an external HDTV tuner to be able to pick up channels. When you have an HD-ready, HD-compatible or HD-capable television, there is an tuner built in.
However, this tuner can only provide you with traditional, analog (NTSC) signals. For this reason, you will need an external HD tuner to get HDTV signals.
If you have an HD-integrated television, there is a built-in tuner for analog and HDTV formats. With an appropriate HDTV antenna, you can easily pick up broadcast stations in both formats. HD-integrates TVs are perfect with external set-up box to maximize HDTV features and receive more channels.
Choosing the HDTV tuner can be a tricky task, especially for first-time consumers. Learning the specifications of your television and discovering the type of accessories that works best with your television is important to ensure that each add-on you buy can maximize the potential of your HDTV, instead of giving negative effects and wasting money on products you did not need in the first place.
