The viewing angle of a TV is the off-angle axis that happens when a person watching the TV moves away from the 0 axis degree right in front of a TV.
Simply said, it is the specific angle in which the picture quality of a TV starts to decrease when watched from the side. A TV always comes with a better picture quality when it is viewed directly in front of the TV screen.
Along with viewing angles, are terms such as side-angle viewing – also called off-axis viewing. They are often used in order to describe that specific scenario in which you are not viewing from the center.
To further elaborate on that, the angle can be about 30 degrees off-axis, or even 45 degrees from the side before the contrast begins to degrade.
If you are the only viewer of your HDTV, for most intents and purposes, the viewing angle is not actually a major issue, so long as you can directly situate yourself right in front of the TV at the best position, staying there all the time.
The comparison on viewing angles is basically straightforward. To start off, plasmas make it possible for viewing the screen from any angle, that is, up to 180 degrees, both horizontal and vertical.
This provides the assurance of virtually zero deterioration in brightness, black level, crispness or reproduction of the image.
On the other hand, with LCD TVs, LED backlighting does not provide a major impact. This is because they suffer from obvious image degradation when they are viewed at progressively wider angles towards the sides, below or above the dead center.
The viewing angle in which the quality of image stays optimal can be about 30 degrees from the center. This is basically due to the way in which this technology actually works.
On the other hand, with plasma, each particular pixel casts its own light directly from the screen. With LCD, the light source is basically the backlight that is at the back the twisted liquid crystal.
Reality is that whether or not viewing angles can have an impact on your television viewing experience, highly depends on several factors, including the basic technology of a TV, the quality of the particular model and the extremity of the viewing angle that you are talking about.
In general, LCD TVs often have a problem with viewing angles. LED TVs also face this kind of problem, as they are LCDs equipped with LED backlighting.
However, with the advancements introduced by technology throughout the years, viewing angle is no longer that big of an issue that it once was. As a matter of fact, in most modern models, you just need to have a very extreme angle so that you can just be looking towards the side of the TV in order to notice the problem.
If you feel worried about which TV viewing angle is the best for your viewing needs, you may want to consider buying a plasma set, since there are no issues when it comes to viewing angles. Of course, it is still important to expect that there will be distortion that is caused by the angle in itself.
In fact, even plasmas come with their set of issues, such as heavy power consumption. However, with advancements in technology, these issues have also been cleared up.
The TV viewing angle represents the limit of a television’s optimal picture quality. By sitting at a position that is at a wider angle compared to the viewing angle, you can only experience worse picture quality.
This may not be important for individuals who sit right across their TV, but can also make a difference in setups in which the seating is off to the sides, just like bigger living rooms.
On the other hand, if we are talking about HDTVs, which are basically the more modern offering in the television world, it is best to depend on the recommendations of the manufacturers.
The range recommendations are often available in groupings. You can select from the list recommended by the manufacturer but, generally, a 10-degree viewing angle is the approximate angle in which an NTSC TV is generally viewed from and this can be the basis for selection as well.
