‘Tis the season for giving … Or for getting a good deal! The advertisement listing code can read like another language. In the quest to find your next TV, you may see details such as:
Samsung LN46D630 46” 1080p 120 Hz LCD HDTV
The above code will be deciphered by going through each portion individually. While Samsung is pretty well known as the manufacturer, and most would recognize LN46D630 as a model number, there is a slew of other numbers and letters that make up this code. Look below and you’ll see each specification in order relating to above example:
Specifications
46″ is the diagonal measurement of the TV screen. Whether it says 32″, 40″, or any other number, the TV measurement always refers to the length of the screen diagonally.
- When considering size, you should consider your room size, as well a s how far away you sit from the TV while enjoying your favorite shows.
1080p stands for 1080 progressive. This refers to the resolution of the TV.
- Resolution is the clarity of your TV. If you consider all the dots that it takes to make one image, the larger number of dots will result in the best image because the image is more densely created. Higher resolution on HDTV models are especially beneficial.
120Hz refers to hertz. This number can be as high as 240. Higher numbers are better for watching sports and other action shows. This affects how quickly the screen changes images so the actions are smooth.
LCD is the type of TV screen, as are LED and Plasma.
- LCD stands for liquid crystal display. LCD screens are best in a well-lit room due to its use of a backlight as well as the use of existing room light. These screens come in wide variety of options available and are energy efficient.
- LED, this stands for Light Emitting Diode. This screen works in the same way as an LCD screen, but the backlights are LED instead of fluorescent ones. LED are also considered more energy efficient than other options.
- Plasma screens, come in larger sizes. They have excellent picture quality, and are good for watching sports and action programs.
Contrast Ratio is not too important, and as you can see, it’s not in the example above. If you are comparing two models from the same manufacturer, you will want to choose the TV with the biggest difference. However, from manufacturer to manufacturer, it is not as big of a deal.
Other important things to note are the various accessories, cables, and warranty options available to you.
Accessories
These days, just about everything comes with optional accessories and televisions are no different.
- Built-in speakers are often inadequate for viewing pleasure. Buyers may opt for portable speakers strategically placed around a room for the optimal experience.
- DVD players are popular devices with a laser assembly that shines the laser beam onto the surface of the disc to read the pattern of bumps. The DVD player decodes the MPEG-2 encoded movie, turning it into a standard composite video signal
- Blue-ray players use an optical disc format developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data.
- Media boxes allow for the use of streaming media to be displayed on your TV (Note: If you buy a Smart TV you can get these media features built in and thus do not have to buy these extra boxes)
Types of media boxes:
- Roku
- AppleTV
- Logitech Revue
- Boxee Box
- Slingbox
Smart TVs
Some TVs, dubbed “Smart TVs” have access to additional features already built in to the tv. Through a simple menu system one can search for movies, shows and videos via online services and across connected devices, browse the web from your television, chat with friends, and access apps. Smart TVs have applications to stream media and interact with the Internet, thus eliminating the need for an extra media box like a Roku or Apple TV.
Connections/Ports/Cables
Coaxial Cable
- The cable that comes from the wall to the back of the TV.
HD
- HD connections are either Component (5 cords, similar to composite (red/yellow/white)), or HDMI. Don’t forget, you must have an HD antennae or subscribe to HD service through your provider. It is good to have 2 or 3 HDMI connections since this is the most popular and widely used connector for DVD, Blue Ray, etc…
Ethernet Port
- This is used to connect your TV to your home network and get on the interent or use Smart TV applications
Wifi – Like Ethernet, but wireless which can be handy to eliminate cables.
Composite
- Composite video originally was created as a solution for television’s transition from black & white to color. It is unable to completely separate the colors, and does not provide a very clear signal.
S-Video
- S-Video solved some of the problems that came with composite video. It provides better color separation and a much cleaner signal. S- Video does so by keeping separate the color and picture parts of a composite-video signal. This is rarely used anymore.
PC Input
- Some TVs allow you to connect your PC directly to your TV to watch slideshows, your websites, or stream TV shows and movies through your computer.
Component
- Component In video improves the picture quality by not only separating the color from black & white portions of the picture but by further splitting the color information into two signals. Component video is the predominant method of hookup from HDTV set-top decoders to HDTVs.
In – or – Out
- The term TV-In refers to audio/visual signals, also called “AV signals” from electronic equipment that generates AV signals.
- The term TV-out refers to the connector of equipment providing an analog video signal acceptable for a television AV input. TV-out is different from AV-out in that it only provides video, no audio
Warranty
A Manufacturer’s Warranty is generally included in the cost of the television. The range of how long of a warranty you are given is from 90 days to a couple of years.
Extended warranties offer extensions of the warranty provided by the manufacturer, and cover the TV in case something happens after the expiration of the manufacturer’s warranty or in some cases problems that occur outside of the manufacturer’s covered problems.
