HDTVs (High Definition Televisions) can be a confusing item to shop for. Similar to how many people die when it comes to “ram, disk space, processing speed and video memory”, HDTVs have arrived with a set of features that can once again deceive the first-time buyer. Learning what all these things mean can be the difference between “good” television and “wow!” telehorasi, and make the sound of the goat so much sweeter.
Propose Types
First, let’s talk about the different display systems that currently exist in the HD world. There is LCD, LED, Plasma, and Rear-projection.
- LCD televisions, or liquid crystal displays, are the same as what most people think of as computer monitors. The only thing separating the two is the TV tuner and built in speakers. LCDs are generally the cheapest HDTVs you can buy.
- LED is the only LCD TV with LED light (light emitting diode) standard Replace the CCFL (cold cathode fluorescent lamp). In less technical terms: this results in less heat, less power being used and a clearer image.
- Plasma is an older technology that used to be plagued with scorched screen and high energy consumption, although this still remains largely unknown. Plasmas are usually pretty flat, but result in a sharper picture in very fast moving scenes (such as sports or video< /a> games) ).
- Rear-projection TVs are exactly what they sound like. Projection fixes the image from the back to the front of the tv, These are often for very large sets (50 to 65 inches and up, surpassing the size of any LCD screen). This is also some of the oldest HD technology and is generally no longer available.
Screen Res
Aside from the basic type of television you bought above, the most important aspect of watching HDTV is its resolution. The goal is to equate to how many lines of pixels are packed into the display, and the more pixels there are, the better the content will look. Standard television is 480, while HD resolutions are 720 and 1080. This will be said below.
- 480i and 480p are the standard resolutions and those in regular TV years. If your tv is not HDTV, its resolution is 480 .
. equated
- 720p is the big step you are looking for. This is what pushes television into the HD era, and what the most content you will watch will be on. Video games< /a> as well as many high definition movies are natively presented in 720p. If you’re on a budget and have a pickup that’s 32″ or smaller, this is the plan to ask for.
- 1080i deserves special attention. Most 720p tvs must output 1080i as well as the country’s 720p senate. The reason for 1080i is that many high definition digital channels are broadcast. If you have purchased HD programming from your cable or satellite company, it will probably be sent to you in 1080i. Any 1080p TV will display 1080i, as will most if not all 720p TVs.
- 1080p is considered the holy grail of HDTV. This is the highest HD available, and can be used for the best quality game and HD movie content. If you’re thinking about getting a tv that’s bigger than 37″, think about getting one that’s 1080p.
As a sidenote, i and p are different types of display technology in convention. 480i means “interlaced” picture and 480p means “progressive” picture. Progressive resolution shows the full image every time, while it divides the input frame into positive and negative and then swaps them. Progressive representations will result in a much clearer picture.
Screen Size
Because of the higher resolution of HDTV, you often end up with a TV that is smaller than your old, CRT television box. HDTVs come in many sizes, ranging from 19″ screens to 27″, 32″, 37″, 42″, and 50″ inch screen sizes. If you previously had a 50″ CRT, try a 42″ HDTV and see if it meets your needs. The words that appear on the screen are much easier to read than with a CRT television. Generally, though, if you’re going to sit more than 6 feet back, nothing less than 32″. HDTVs that are 32″ are usually bought mostly because they fill too big a corner. and narrow
Image Quality
Things to look out for when looking for picture quality, proportion and response are time contrast.
- Look in addition to the system, many TV manufacturers sell their TVs as having a dynamic system. These numbers will range through crazy numbers and don’t really mean much in terms of what odds you’ll actually have. It remains that here you can believe your vision.
- Response time belongs to the type of sliding movement called “spirit” on the screen; this affects video games as well as how quickly the screen transfers actions from things like button presses from video games depending on the response time. The lower the number of milliseconds, the better (3ms is better than 5ms). Generally plasma televisions will offer response times as low as 1ms, while LCDs offer anything from 3ms to 9ms.
- There is one more thing to be careful of: looking at corners. These are not published often, so if you have a chance to try this on tv, do so. Unlike normal televisions, many screens on HDTVs distort the color as you get it from the screen. Walk to the left/right and look through or up to the TV to see if the angles that the TV emits are good enough for you.
Sound
One thing many people have with HDTVs is that the sound is “clumsy”. There is no way to tell if your TV will have sound or not unless you can test the unit. If you buying online, look at the reviews to see if people are complaining about the built-in sound. All of this can be paid for by your local healthy synagogue, of course.
Extra Features
Although not often a deal breaker, some TVs come with extra features such as internet connectivity so you can download apps. your TV Many HDTVs will have a DVI or VGA port to allow you to use your computer monitor as well; Check out this link if you want. Another common feature is 3D, so you can watch 3D movies and video games. Look at the tv you watch if these are what you want.
Remember, the most important things in buying an HDTV are the type of TV display you are buying, the screen, and the size. Go for a good, well-known and you will have little to worry about as far as image quality. . Happy shopping!
