28 Apr 10 What Size HDTV Should I Be Considering For My Room Space?

When considering standard-definition TVs, it used to be the case people watching would be comfortable with watching the screen from a distance that was approximately between three and six times the screen size when measured in inches. This is not the case with HDTV. Because the resolution is far better than the standard definition, it is possible to sit much closer to the screen without the possibility of noticing pixellation. As a consequence, then, with HDTVs, you are able to have viewers seated between one and a half and three times the screen size in inches in distance from the screen to obtain the best viewing experience.

These guidelines have been designed to present you with the information regarding the best position to be seated in relation to the new TV. If you approach it from a different perpective, in order to work out the size of TV you have to purchase, what you have to know is the size of the room where you wish to locate the TV as well as where you want to be seated and where the TV is to be located in that room. As a result, what will be the size of the TV you are going to opt for?

When the calculations are performed in reverse order, the following formula is the result:

Minimum size = Viewing distance/3 Maximum size = Viewing distance/1.5

calculate the maths straight off, you may get some rather unusually sized numbers, so it is a good idea to round off the calculations as they relate to the sizing of existing HDTV sizes before completing the calculations in order to achieve a handy chart:

Viewing distance in Feet = 04, Min Size = 19in, Max Size = 32in Viewing distance in Feet = 06, Min Size = 26in, Max Size = 46in Viewing distance in Feet = 08, Min Size = 32in, Max Size = 63in Viewing distance in Feet = 10, Min Size = 40in, Max Size = 80in Viewing distance in Feet = 12, Min Size = 46in, Max Size = 96in Viewing distance in Feet = 14, Min Size = 52in, Max Size = 112in

If the TV you wish for your area is 40 inches or less, a flat-panel LCD TV is your best bet. Between forty-two and sixty inches, you'll select between plasma, LCD, or rear-projection sets. Plasma HDTVs tend to be the most popular selection in this size category, as they offer excellent image quality and flat-panel allure. Flat-panel LCDs are now competitive in value with plasma within the 40- to 46-in. sizes, but generally not on the market over 52-inches--and at that size they can be pretty expensive.

For those people whose room size demands a massive screen size, the most straightforward answer is a rear-projection TV. The picture quality produced by the rear projection TV is outstanding, but the size of the unit is a negative concern. Most flat panel HDTVs are around four inches thick, whereas the rear projection TV can be anywhere between ten inches and sixteen inches, so you are not likely to be contemplating hanging one from a wall. It is an interesting fact that,however the majority of people who choose flat panel HDTVs (like this one: Toshiba 32av615db Review) do not hang them on the wall, either.

There is yet another alternative for rear projection, which is the LCOS, or liquid crystal on silicon. The technology that underpins this development is highly regarded with regards to the picture quality. It is currently only available in full 1080p models. LCOS can be considered a generic term as there are two completely different interpretations of the technology: one is evident in the HD-ILA TVs as developed by JVC and the other is the SXRD unit developed by Sony. There are a number of rather subtle differences with regards to the technology employed in each example, although both have the capacity of producing images of outstanding quality.

Should your particular situation demand that you purchase the biggest screen size possible (and it is quite OK to admit to this desire!), then it is quite likely that your purchase will be either a rear projection or front projection unit. Rear projection TVs can be sourced in sizes up to seventy inches, or a little more with some brands. In anyone's language, that is a seriously big TV! Of course, before you even think about selecting such a huge TV, you would have to carefully calculate the room size to be absolutely sure that it would fit. For anything over seventy inches, a front projector should be considered. These units are also known as home theatre projectors or home entertainment projectors.

The reason why people choose to buy a home theatre projector is solely dependent on the quality of the sound they deliver. The image is projected forwards, much like that in a movie theatre. The technology utilised in these units is identical to that utilised in a rear projection TV. Should you be considering the purchase of a home theatre projector, then the quality of the screen onto which you will be projecting the picture should also be considered. You should also remember that home theatre projectors do not include a built in TV tuner, as their sole purpose is to project a picture onto a screen. If your requirements are such that you will need to use the projector as a TV, it will be necessary for you to connect it to either a DVD player or an external tuner. If you are seriously contemplating such a significant purchase as a home theatre projector, then it makes sense to also factor in the purchase of a HD DVD or Blu-ray to ensure the quality of your movie viewing. Why? Because standard definition pictures project poorly when large dimensions are involved. You should also factor in the extra expense of a good quality screen.

When all things are considered, it is absolutely your decision as to what screen dimension is the best for you. Is it absolutely crucial that you buy a huge screen for your viewing pleasure, or will a smaller size fit the bill? Will you be viewing quite a number of movies such as action movies, or music videos where a brilliant sound system is required to get the most out of the experience? How far can your budget stretch? All these questions and more have to be factored into the purchase of your HDTV.
