Buying an HDTV can be difficult to practice for the newcomers. In the past, the small size of CRT TVs, as well as technological limitations and poor analog signal made our choice easier, CRT televisions substantially resemble an average distance of listening. HDTV is now available in various sizes ranging from 28 inches to 65 inches, and in many different technologies. This has a significant impact on the optimal viewing distance in relation to the size of the TV, and is probably the first thing you should think before you leap.

There are many factors that influence the optimal distance vision. Please note that the factors below are primarily for fixed pixel technologies (plasma, LCD).
1) Summary Detailed Perception

The last really HD revolution provides detailed images on larger screens without the annoying artifacts inherent in the standard analog transmission. In modern flat screens, images are formed on a grid of pixels cramped. Imagine watching this game to a very small distance, you will immediately appreciate the jaggies “,” problems that affect some viewers. But if you walk slowly, you can see the pixel grid gradually disappear to form a uniform image. At this stage, you can view all the information that was provided when the photo was transferred from a digital master.

Now that the optimal distance vision is obviously influenced by the individual visual acuity and its environs. But in general, the level of pixelation is about 1.5 times the distance of reading, TV to 1080 hardware. If you move further away from the image begins to lose the details of this merger pixel to know one another. not be able to bring out the details of an object at a distance.
2) Viewing Angle

SMPTE and THX recommended viewing distance should also provide optimum viewing angle of 30 degrees for a cinematic experience. It ‘more difficult to control in home situations, but it is possible on some TVs or projectors big house. However, I doubt that acting in favor of maximizing information and eliminate the effect of pixelation before.
3) Resolution HD Equipment

Most HD sources are encoded in 720 or 1080. This is important because if you think about it, 1080 supplies the most detailed of a material 720 on a screen 1080. So, if you upgrade the resolution, you can sit near the TV and enjoy greater detail and viewing angle. Let me clarify this point, in our example below.
TV Size 4)

TV size and viewing distance are related. Changing both the aspects always change the size of the TV in your eyes.

Ok. Here’s an example.

Some rules.

1) The distance vision – too close, aliasing. Too far, the loss of detail.

2) Size of TV – Too big, jagged, too small, the loss of detail.

3) the resolution of the tools – too low, rugged, high, motion sickness. (Haha, talk another time.)

4) All changes to the items listed above, must take into account that eliminates pixelation ever before, and then the details to maximize the “optimal” distance.

So, in my guide, assuming 1080p TV can:

TV 40 inches diagonally – 720 records – 8 feet (retail pixelation optimal threshold)

1) Buy a bigger TV (50 inches) without changing other risk factors mean that you run the deterioration of image quality because of pixelation increased. Using the above rules, you can sit further (10 feet) or increase the resolution in 1080 to counter this.

2) Increase the resolution of the issue in 1080 did not cause pixelation, but you may lose the additional detail it provides. In fact, the issue of 720 and 1080 are indistinguishable at this distance for the majority of viewers, all things remained the same. The new optimal distance should be about 5 meters. Instead, look at poor resolution means that you must sit to avoid aliasing.

3) Change of distance for an effect siimilar changing the size of television. If I sit too close to the TV, I need a small television to counter its effects, or watch the content at high resolution.

So that’s it for now. I have included a table for remote viewing, the size and resolution of TV content in 1080p widescreen TV. The media have revealed, but also have a viewing angle of 30 degrees.
576 Resolution 720 in 1080
32 “8 ‘feet and 6′ 4 ‘
37 “10 ‘7 ‘5 ‘
40 “10.5 ‘8 ‘5 ‘
42 “11 ‘8 ‘5 .5 ‘
46 “12 ‘9 ‘6 ‘
50 “13 ‘10 ‘6 .5 ‘
52 “13.5 ‘10 ‘7 ‘
65 “17 ‘13 ‘8 .5 ‘

* The above is the minimum distance from the base of a TV 1080p
