1080p HDTV

Since the early days of television, the ultimate goal has been to bring the movie theater experience into the living room. After many years of research, high definition television (HDTV) is the realization of that goal. It provides superior picture quality and a widescreen format, along with surround sound when the right speaker system is used. There are several high definition resolutions in use today, but only 1080p HDTV is capable of showing pictures in full high definition. To confuse matters even more, buyers need to be aware of the difference between interlaced and progressive scanning, as the former is markedly inferior to the later.

The change from the original format to high definition was a defining moment in the history of television. The quality of the pictures and sound was substantially improved, and the widescreen format provided a more natural way of watching television. People see the world around them in widescreen, so it was always a bit awkward watching television with a square picture format. High definition also made it possible to build televisions with larger screen sizes, which are more enjoyable to watch because they have a greater visual impact. The increased resolution of high definition allowed screens to grow while their pictures remained sharp and clear.

In the past, resolution was not a consideration when choosing a television because it was the same for all nearly all models. Today, there are several different resolutions to choose from, which makes buying a new television more confusing than ever before. Choosing the correct one matters because it makes a big difference to the picture quality and price of a television. A large screen looks worse than a small screen if the native resolution is not high enough to prevent a blurry picture. The best models currently available have a resolution of 1920 by 1080 pixels with progressive scanning. This is commonly known as 1080p HDTV or full high definition.

Some people wrongly believe that only large screen televisions can show full high definition, but the screen can be any size so long its native resolution is suitable. This is the resolution that the screen was designed to show without any resizing of the picture. Another common mistake is to assume that a television is 1080p HDTV just because it has a full high definition tuner. It does not matter how good the tuner is, the picture will end up being resized if the screen does not have enough resolution to handle it. When buying a new television, ignore the labels on the box praising the virtues of the tuner and check if both the screen and tuner are full high definition.

Even more confusing than resolution is the difference between progressive and interlaced scanning. The “p” in 1080p HDTV stands for progressive scanning, but there is also an interlaced version at this resolution, called 1080i HDTV. Scanning simply refers to how the picture is shown on the screen. Two screens can have the same size and resolution but have different picture quality if they scan differently. Interlaced scanning is considered inferior to progressive because only half of the picture is shown with every frame. Alternating between the frames effectively cuts the frame rate in half, which makes the picture look worse when there is rapid movement. Essentially, the main point to remember is to always go with a television that has progressive scanning.

Given that 1080p HDTV has the best picture quality available, it should come as no surprise to learn that it is also the most expensive type of television. It is the main reason why some large screen models cost hundreds of dollars more than other models with the same screen size. The price difference has narrowed in recent years as 1080p HDTV grows in popularity, but it is still large enough to make some people consider buying a television with a lesser resolution. Full high definition is not that important for small screens, but it should be considered an essential feature for screens that are thirty-two inches or larger. At those sizes, 1080p HDTV is definitely worth the extra cost for a sharp and clear picture.
