If you have a look at my LCD flat screen TV, there's no doubt that you are about 120Hz models of reading. Are probably wondering if the models with a value of 120 Hz, the costs are. The value of the function is 120 Hz has been much debate in recent months. There are a number of things to consider before the decision.

In the early days of war LCD or plasma, one of the biggest drawbacks of buying an LCD TV is that they tend to blur, and a bit 'choppyImage, especially in times when there was a lot of fast action like sports or movie scenes like car chases. Although managing a vast improvement over the years, television in the ability to fast movements, so LCD is still fighting against the stigma of not having a picture as smooth as a plasma.

Enter the TV 120Hz. As an immediate response, has integrated 120Hz LCD TV TV manufacturers in their newer models. These televisions have refresh rates, which is twice as fast as the"Standard" 60Hz models.

Those who are followers of 120Hz technology argue that the image is visibly smoother with crystal clarity, especially in scenes with fast action or sports. Another advantage is the ability to produce an image almost 3D.

On the other hand, others say that you can see no difference when comparing side by side with the "standard" 60Hz models. One has the feeling that the 120 Hz models are simply marketing gimmicks to sell at higher pricestv.

So who is right? As usual, there is a middle ground. In short, a 120Hz TV is easy to replicate a standard 60Hz signal and twice for what is little improvement in the quality of images. The real difference is when the use of a video processing function to improve the movement. Every society has its own name for this process. For example, Samsung Electronics is a feature called AMP for automotion Plus This feature is the screen, and interpolates the image to provide aReduce vibration image smoother.

If the movement is a further improvement in picture acceptable? Even this is not decided yet. Improved Motion at its best offers a significantly smoother, more stable image, free from Jutter, motion blur and ghosting. Some describe 120Hz games that have a 30 frames per second, like a game with 60 frames per second game, while others looked at the ability to live sports and movies in 3D and are fascinated.

In the worst cases, improved movement,especially during fast motion can be divided to introduce noise distracted in the second image as artifacts that may be apparent. Others believe that as sort of documentary that shows how stable Planet Earth breathtaking live action scenes may provide that the motion is carried away by the improvement in film with a film seems almost too realistic, live TV or soap operas, rather than a true cinema experience.

It 'important to note that exercise equipment can be switched on or off,So, if you prefer, a movie without the exploitation of the movement, you can simply turn off the clock.

At the time of elections, with a 120 Hz LCD flat screen to do, is a purely personal choice and budget. Note that this is a very new technology and, like all new technologies there are still some things that must be completed. Discusses little 120Hz is the wave of the future and the technology only improve with time. If the course is not the primary concern orIf you avoid the dollar in more than an attempt to future proof your TV then buy seems to be perfect, with the additional features and benefits that can come with a 120 Hz LCD flat-screen TV offering. If the price is a primary factor, and working on a limited budget then a standard model would be a good choice to be perfected, the 120 Hz models

Optimum size of the TV screen is directly related to the distance available for viewing – but there are other factors that must be considered.

Viewing distance: It 'only a matter of personal taste?

Sit too close to the TV to the big screen and be able to see the image build-up structure – scanning lines or pixels forming the image – in order to distract the attention and enjoy your home theater experience. But sitting too far away, andthe effect is lost.

There are different opinions about the best way to determine the optimum TV viewing distance for a specific screen size. Just go to the movies and soon you will realize that everything is a matter of personal preference – some sat in the back. Others would jump to the front row, as they prefer a larger screen and a broader perspective, while others would simply choose randomly located halfway between these extremes.

Truthis that there is no scientific rules her. This does not mean that there are guidelines that you should follow when planning an acquisition or a big screen would-be home theater room.

SMPTE Recommendations and the THX certification standards:

The Society of Motion Picture and Television Engineers (SMPTE) recommends that the screen size for the home theater would occupy a 30-degree field of view – the horizontal plane – for the public. Alternatively, the TV ideal canViewing distance should be such that the width of the screen has an angle of 30 degrees to the upright position.

These were 30-degree viewing angle seems to have adopted widely regarded as the standard for home theater and movies.

The directive SMPTE is also in line with the THX certification that the standards recommend that the rear row of seats must have at least one angle of 26 degrees, and lawyers, while an optimal viewing angle of 36 degrees.

It isbelieves that, within these limits is a better perspective of the viewer is lost in the action movie itself.

Vision System limitations:

It 'also the question of TV viewing distance visual acuity. This is not the optimum viewing distance – but refers to the maximum distance to go display some details about the image is lost.

Technically, the visual acuity is a measure of 'eye and shows the spatial resolutionangular size of the smallest detail that can solve a system of visual person. A person with 20/20 (or 6 / 6 when expressed in meters capable of solving) normal vision of a spatial model from a viewpoint of a minute which is the angle arc 1/60th degree of self in the eyes when viewed at 20 meters away. In other words, a normal person with 20/20 vision can identify an object with a height of 1.76 millimeters to 20 feet is capable of doing.

Distances in television, these represent the numbersome of the viewing window will no longer be solved by the vision system viewer.

So how to explain it in practice?

Some rules-of-thumb to help put into practice the guidelines above. These rules for viewing distance to screen width, not in diagonal screen and then apply for both 4:3 and 16:9 display formats.

A general rule for TV viewing distance of the SMPTE and visual acuity is based guidelines is thatthe nearest TV viewing distance between you and your big screen TV should be limited, approximately twice the screen width (more precise 1.87 x screen width for a circular circumference angle of 30 degrees), while the distance more, no more than five times the width of the screen.

This rule of thumb should give you an approximation good enough for the distance of TV viewing. Is not necessarily the perfect home theater viewing distance, but the limits within which the TVViewing distance should theoretically zone trouble.

In other words, more than twice the width of the size and image scanning lines, points and other video artifacts will be visible too intrusive – that spoil the distractions that you will be film. They continue to move away than 5 times the width of the screen and the vision system will no longer be able to resolve every detail of the image.

But …

It 'also important to recognize,that these minimum and maximum viewing distances should be considered in light of the definition of the video signal.

A fully resolved high definition TV (1080i, 1920×1080) supports a greater distance than standard analog TV viewing. Thus, while twice the screen width would be the ideal TV for only a HDTV display, it would be a bit 'too close for standard TV, in the case, three times the width of the screen may be the best choice.

The times of five screenWidth of the maximum visibility, while more than adequate for a standard analog TV picture is a bit 'too far for a support person to the smallest detail of a picture HDTV – three to four times the width of the screen displays a practical limit the maximum viewing distance in the case of HDTV.

These rules-of-thumb work best with a large screen TV in the range of 42 inches or more.

When it comes to the use of regular size standard-definition analog TVthe home theater, ie up to 36 "/ 40" diagonal, the optimum viewing distance is between 8 feet and 12 feet. TV under 36 inches are not big enough to have qualified for home theater use, the small screen size is not the desired effect on the viewer.

Vertical viewing angle and height of the screen:

For optimal viewing of the eyes of the viewer should be level with the center of the screen.

Maximum vertical viewing angle: In the home theater –set-up in case this is not possible to beat the SMPTE guidelines, the maximum vertical angle of the top of the image projected on the eye level when seated in the front seat middle row should be measured not more than 35 degrees.

This charge does not represent the optimum viewing angle, but the boundary that are subject to the spectator, an increase of the neck.

The maximum vertical angle is always measured from the front row, because these are the far cornerview.

Minimum angle: Although it does not seem to be a specific SMPTE or THX guidelines in this area, but studies have shown that when the screen size takes less than 15 degrees vertical field of view, the viewer that the small picture is displayed.

Practical Considerations:

In a typical home theater-up, is not necessary to bring about the vertical angle or really care, not even the minimum requirements for a vertical angleCinematic experience effectively.

If one of the recommended TV viewing distance of twice the width of the screen to keep (as detailed at the top of the Directive SMPTE 30-degree horizontal field of view), would automatically satisfy the minimum angle. The reason is that there is a fixed relationship between the height and width of the screen to your home theater screen aspect ratio of 16:9 or 4:3.

And still more: in a typical houseSetup Theater, would be very difficult, the maximum vertical angle from which you are subject to a greater cross neck strain.

Considering that most home theater rooms are approximately 10 feet (3m) is high, the resulting vertical viewing angles and within the normal limit of 35 degrees in the detailed guidelines SMPTE – everything you need to do is within twice the width screen guidelines for your eyes to stay apart.

When you are ready, the old cathode-ray tube TV business and buy an HDTV flat screen TV, then you need to learn some things. Because of new technology companies offer, there's more to do with the purchase of TV than ten years ago. Do not worry, though! Follow the steps in this article and for the purchase of your next HD flat screen TV will be without problems!

The first thing you need to find out is that TV resolution you want. There are basicallythree resolutions, 480, 720, and 1080 These figures refer to the number of TV lines if it makes your scanned image. The higher the number the better the resolution. 720 and 1080 are considered high definition. 480 is standard.

The next thing you know is what to do on your TV flat screen HD. I know that you are going to watch ", but exactly what you want to see? Is not expected to use only the cable and DVD? OYou want to playback video-style games on it. What other hook-up you need?

Thirdly, you must decide whether a plasma or LCD TV will. Both have their advantages and disadvantages. The advantages of LCD TV is that they are lighter, so as to facilitate wall mounting. The screen does not reflect light, so you can use in a highly illuminated. Consume less power than plasma televisions. In addition, their images are brighter. The disadvantages are problems with pixel-tax, which could make the pictureGhost. You can also set pixels. (Make sure you thoroughly inspect the TV when it is delivered.)

Plasma TV and have response times faster, higher levels of brightness. They also have a higher contrast. The image on a plasma television is more film. The disadvantages are static images can lead to burn-in screen. Furthermore, this type of HD flat-screen TVs will require additional support when assembled. They are much heavier than LCD TVs.

With all this in mind, you can choose theWho buy from producers. Sony, Samsung, Toshiba and Panasonic are the main producers at this time. Are very competitive with each other, and because the prices have come a lot last year or two years. Samsung offers perhaps the best choice, but all four of these companies make a good product.
