Many people head to buy a new HDTV but have no idea what all the technical resources and overwhelmed when shopping. Sale of different people expressing different opinions, and, finally, many at the end so that confusion. What do these terms mean? Here is an overview of some of the main features and what to look for it.
First, before going into detail, we are talking about the technical specifications for marketing "talk" to. Specifications are aspects of a> HDTV (consumer or otherwise) that are easily verifiable by industry-standard tests. A kind of contrast ratio may in fact be verified by a standard test, while the marketing is talking of something designed to help try to be the sale of products, and often can not be verified or not, once recovered. This is usually in the form of something that sounds impressive to come, but it is not easy to quantify. For example, if the picture of HDTV to announce something like "IntellicolorAdvanced II razor-sharp pictures for the major, who is seeking only a proposal marketing term, their product sounds amazing. In fact, if you look at the box HDTV is another manufacturer that the feature is not available "equal" in the list. This is because their marketing department has developed some of the most impressive features of other probes, which will make a better product.
However, this does not mean that this concept of marketing is not based on something real, like a certain functionHDTV 's equipment or software, but often when you try exactly what you're talking to a provider or check the Web sites of the manufacturer to ask, will not be able to get a clear answer. And sometimes it is a cost-TV from the same manufacturer have the same function, but the list in the table because they want to see the highest price of the most impressive. In my opinion, for the most part is simply to ignore these conditions. If this seems impressive, elegant and vaguelySpeaking of marketing.
Actual specifications and their significance. Allow the most important, know what they think, what you should look for when shopping for your HDTV.
Resolution
This is the first thing you should be when shopping for an HDTV. Often you will see terms such as 720p, 1080i or 1080p. This is to show how their television pictures. Every picture on your HDTV is encouraged by small pointsPixels, each pixel and shows a small picture on the ground. For example, in fact indicated 720P of 720 TV lines of pixels on the TV, and 1280 columns of pixels. When I point out that looks like a table with 720 rows and 1280 columns, see, and each small square in the table is a pixel. This means that a 720p HDTV actually contains 720×1280 = 921,000 pixels.
A 1080p is actually 1080×1920 = 2,073,600 pixels. This means that there is indeed a 1080p pictureMore than 2 million points and give a much clearer HDTV 720p. If you see a TV or an HDTV with a resolution other than one of them on the market, stay away from him, and will not be able to view the image without the scale larger or smaller to see, not the best image.
It 'also important to note that a 1080p HDTV can display 720p, and just resize the image to fill the entire screen, the television can usually 720P1080p display an image, but there are (and lost in the process of dissolution).
My recommendation is ready 1080p, will give the best resolution in general, and how to view HD content on TV again, you know that you are the best possible resolution. However, as the difference between 1080i and 1080p is a difference, as the image displayed on the TV screen. Most people will not be able to distinguish the difference, but if you know betteris 1080p, 1080i, but if your TV is convenient for you, and the picture looks very good for you, be assured that there will always be good TV.
Contrast Ratio
The contrast ratio of TV is getting blacks blacks than whites, white preserve. Home LCD TV showed a very poor, however, as the blacks, in a scene has never been black and white never seen him so brilliantly. This became a problem when you see a movie, and there was a scene in whichCharacter entered a dimly lit street, for example. The television would not be able to discern the difference between all these dark colors, and something like a mud Mess Black and lose many details of the image, not only for the TV show in fact a subtle color variations in the image.
The good news is that the technology is now much improved, and that most TVs on the market much better. If you look at the numbersIncreases the contrast ratio is a better picture. As an HDTV with a contrast ratio of 1000:1 would be much worse than with a contrast ratio of 80000:1. The higher the number, the better for you.
Refresh Rate
Recently it has been an outlet for high-definition television. They see this as 60 Hz, 120 Hz, and now, 240Hz specified. What and who is better? In short, it must be able to do with the speed of each pixel to change color and Hzbest. Great LCD HDTV was not very good at quickly changing colors, so that programs with a lot of fast movement, it could become one of the camera shake. For some, not so obvious, but if you know what to look for, it is easier to see and be distracted by it. If you're about to buy an HDTV, you find that a refresh rate of at least 120 Hz, one might be tempted to go to one of 240 Hz must, and if you're not sure it's only "real" 240 Hz; Some CompaniesTrying to get people to believe that it was the TV to 240 Hz, but in reality, 120 Hz, that terms such as' a performance comparable to 240 Hz, if you see something like that is probably 120 Hz HDTV There are many more 120Hz TV market of 240 Hz, then you should have the possibility of a 120 Hz TV easy and convenient.
Connection Type
See this listing things like 1 composite video, 1 component video, 1 S-video and 2HDMI video inputs. What does this mean? Take the best from the worst.
Composite Video – the worst of all the items that you need if you have an old VCR or DVD player too old, need to be connected to the TV. Usually on the back of your VCR or DVD player and connecting to see are yellow. Only good for video signals in standard definition (ie we used was the same for years).
S-Video – a decent DVD player has at least oneS-Video. This is usually marked as such and resembles a small round connector with internal connections. You can see how it looks here. Only good for the images in standard definition, but provides better video quality composite video.
Component video – sometimes referred to as RGB connection, because it separates the video signal in three colors: red, blue and green. It is a means for transmitting analog video signals from SD and HD. You can see these threeConnectors on the back of most modern DVD players, decoders, etc.
HDMI – An all-digital connection to your HDTV, which provides the best signal quality. Hi-Def Blu-ray players, game consoles like Xbox 360 and PS3, and cable and satellite have this type of connection. Hidef rapidly becoming the norm, so many of their best.
You should also look for things like coax, it can be for cable TV systems age and require inputs, such as VGA orDVI, if you hope to connect your computer to your TV and use it as your PC monitor.
Endnotes
For more details, you can search your USB ports for cameras to make images, videos, etc., or media card reader, you can use the flash memory card directly on the TV to see upload latest photos that show their families and others. These are not necessary but can help, today announced the final decision on TV offers the best bangYour money.
Ultimately, an important factor in determining the price and video quality in general. If you are the photo and the price and specifications, well, then go ahead and enjoy your purchase of a new one. Good luck!
