Many people head out to buy a new HDTV but have no idea what all the technical details, and get overwhelmed when shopping. Many sellers of expressing different opinions, and leave at the end of a set only at the end confused. What does all this data mean? Here's an overview of some of the information of great and what you should look.
First of all, before discussing the details, not to talk about specific techniques, compared to the "marketing". The technical specifications are aspects of a> HDTV (or other consumer electronic products), slightly with industry-standard tests to be verifiable. Something like the contrast ratio can be effectively controlled with a standard test, and the marketing speak is developing something to help try to sell the product and may often not easy, if ever reviewed. These usually take the form of something that sounds impressive coming, but can not easily quantify. For example, if the field was announced for the HDTV thing as "IntellicolorAdvanced II for better image clarity, "this is just a marketing concept emerged to find and the sound produced is impressive. And really, when you watch a HDTV box from another manufacturer, you will not find that same" characteristic " listed. This is because their marketing department that came with some other impressive feature is their product sounds to play better.
Now, this does not mean that this concept of marketing is not based on something real, as a functionHDTV in hardware or software, but often times when you try to understand what exactly the issue of a seller or the review of the manufacturer's website will not be able to get a clear answer. And sometimes they have a lower price from television producer himself, the same function, but not listed on the field because they want the most expensive TV sound too impressive. My advice is, in most cases is simply to ignore these conditions. If high-pitched sounds and the fantasy and vague,its just marketing speak.
The technical details and their real meaning. We'll go to the biggies, you know what they mean and what you should look for when shopping for your HDTV.
Resolution
This is the first thing you should look for when shopping for an HDTV. Often you will see terms like 720p, 1080i or 1080p. This is because, as televisions display their photos. Every picture on your HDTV is made of tiny dots calledPixels and each pixel shows a small section of the image. For example, a TV-720P actually specified as 720 rows of pixels on the TV, and 1280 columns of pixels. When you pull out, would be similar to a table with 720 rows and 1280 columns, and each small square in the table would be a pixel. This means that a 720p HDTV actually contains 720×1280 = 921,000 pixels.
A TV-1080P is actually 1080×1920 = 2,073,600 pixels. This means that the image is actually up to 1080pmore than 2 million points, and give you a much clearer picture of an HDTV 720p. If you use a TV or HDTV with a resolution adopted by one of the other two, stay away from him in traffic, because you can not l 'image without scale is larger or smaller, and has not shown the best image.
It 'also important to note that a 1080p HDTV, 720p, and can display an image and you will reach the whole screen, how can a 720p TV is usually1080P display an image, but will (make it smaller and you) lost in the process of resolution.
My recommendation is to get a 1080p TV, which will give you the best resolution as a whole, is like watching HD content on the TV again, you know, watching you and the best possible resolution. Now, as regards the difference between 1080i and 1080p, which is a difference in how the image displayed on the TV screen. Most people will never be able to notice the difference, but if you want to know the best1080p is, but if the TV 1080i is better for you, and the picture looks good for you, rest assured, you will still receive a beautiful TV.
Contrast Ratio
The contrast ratio of your TV is black, saw how the blacks compared to white as the whites to receive. First LCD TVs contrast ratios really bad, so that the blacks never really looked like a scene in black and white did not seem very rosy. This became a problem when watching a movie, and it would be a scene in which theCharacter went to a dimly lit path, for example. The TV would not be able to discern the difference among all the dark colors, and everything was like a mess of pottage in black mud, and you lose a lot of detail on the figure, only because television was not capable of the subtle variations color display in reality the presence in the picture.
The good news is the technology greatly improved now, and most TVs on the market is not much better with this. If you are adapting to the numbershigher contrast ratio gives a better picture. Thus, an HDTV with a contrast ratio of 1000:1, it would be much worse than one with a contrast ratio of 80,000:1. The higher the number, the better for you.
Refresh Rate
Lately, today is a plus for HD-TV. They see this as 60 Hz, 120 Hz indicated, and now, 240Hz. What is and what is better? In short, it needs to change the speed with which each color pixel and the higher the Hz,better. Great LCD HDTV were not very good at quickly changing colors, so that programs with a lot of fast movement, you could see a stain on the image. For some people it is not so obvious, but if you know what to look for that to be easier to see and be distracted from it. If you're shopping for an HDTV, you're a watch that has a refresh rate of at least 120 Hz You might be tempted to go for one with 240 Hz, and if you do not, just make sure that there are "real" 240 Hz, how some companies'll try not be fooled into thinking their TV offerings, 240Hz, but it is true that only 120 Hz Look for similar terms like "performance with 240 Hz When you look so similar, it is very likely an HDTV 120 Hz there are many other 120Hz TV on market at the time of 240 Hz, then you should be able to 120 Hz TV, you will find easy and convenient.
Connection Type
We see these things as 1 composite video, 1 component video, 1 S-video and 2 underHDMI video inputs. What does this mean? Let them degenerate.
Composite Video – the worst of all have input, you will need this if you have an old VCR or DVD player really old is expected to have to connect the TV. In general, is on the back of your VCR or DVD player and find the connection has a yellow color. Only good for standard definition video signals (ie the old analog signal that we are already used for years).
S-video – will have a decent DVD player, at least oneS-Video. This will usually be indicated as such in there and looks like a connector with connections smaller. You can see how it looks here. Only good for the images in standard definition, but allows for better picture quality than composite video.
Component video – often referred to as RGB connection, since it separates the video signal into three colors red, blue and green. This is a way into an analog signal in standard definition video and HiDef transferred. You can see these threeConnectors on the back of most modern DVD players, decoders, etc.
HDMI – a digital connection for all of the HDTV signal that provides the best quality. Hi Def Blu-ray players, game consoles like Xbox 360 and PS3 and some cable and satellite boxes have this kind of connection. HiDef rapidly becoming the standard, so that more of them, the better.
They also want for things such as coaxial input, you can use the old cable television systems or means of production as VGA or you need to lookDVI, if you hope to connect the computer to your TV and displays them as with the PC.
Concluding remarks
Other niceties, you may want to try the USB ports for connecting the cameras to make images, videos, etc. and even card readers, flash cards so that load directly into TV on your latest family photos, etc.. looking display. It is not necessary, but it could help the final decision on what TV is to give you the best bang forYour money.
At the end of an important factor in the decision are the price and video quality as a whole. If you are the image, price and good data, then make and enjoy your purchase of a new one. Good luck!
