Why Is HDTV Necessary?


Do you have a high-definition TV? If not, you may be missing out on the best picture quality. HDTVs provide viewers with a better picture quality than standard-definition TVs.

The resolutions of high-definition TVs and standard-definition TVs

The three resolutions that work for broadcast HDTV are 720p, 1080p and 1080i. The “p” stands for progressive scan and the “i” stands for interlaced scan. Standard-definition TVs operate at a lower resolution.

  • What do these numbers mean?

    The numbers each represent how many resolution lines are scanned, which forms pixels. These pixels ultimately create the image on your TV screen. High-definition TV has a higher resolution than a standard-definition TV, creating a better picture quality.

  • Which resolution creates the clearest image?

    1080 TVs, although sometimes more expensive than 720, create a clearer image because there are more lines of resolution and more pixels.

  • Is 1080p always the best option?

    While 1080p is the best resolution available, it’s not always worth the extra money. Experts say that only 50 inches or greater screens will display a true difference in image quality.

    The same goes with the difference between 720p and 1080i – a TV screen 50 inches or greater is needed for a noticeable difference.

  • What resolution is most content displayed in?

    HDTV signals use different resolutions. Over-the-air HDTV usually is delivered in 1080i or 720p. Premium networks typically use 1080i.

The potential downside to HDTVs

Some channels may not offer programs that fill your entire HDTV screen – one reason some people may prefer a SDTV. SDTVs have screens that are narrower than HDTVs, making SDTV programs display unfilled on an HDTV screen.

More than just television shows

HDTVs are useful for more than just TV shows – you can rent and purchase movies in HD these days as well. Blu-ray movies and Blu-ray players are necessary for this.

The reason for HDTV

With the continuous release of newer technology, an HDTV might be necessary. For example, the Xbox One, which was recently released, is only compatible with HDTVs. Emerging technology, such as new gaming consoles and smart TVs, will likely not work with SDTVs in the future.

Ultimately, if you want a better picture image, you should choose a high-definition TV over a standard-definition TV. HDTVs can offer clearer images for both TVs and movies. A noticeable difference between each resolution, however, depends on the size of your TV screen.
