You have many options when looking at 70-inch TVs for your home. When it comes to big-screen TVs, there are several different types and features available to enhance your viewing experience. When choosing the best 70-inch TV for your needs, it's important to decide what features you need.
>> Consider different types of TVs
Almost all TVs sold today are flat screen TVs that can be placed on a stand, mounted to a wall or suspended from a ceiling. However, when you perform a 70-inch TV comparison, you'll find that there are different types of flat screen TVs from which to choose:
LCD: Liquid Crystal Display televisions use less electricity than plasma models. Because they don't reflect much light and have bright pictures, they are among the best 70-inch TV choices for rooms with a lot of windows and little shade.
LCD/LED: Most LED TVs are LCD TVs that use Light-Emitting Diode (LED) backlights instead of the fluorescent lighting used by LCD TVs. The LED light strips are usually placed along the sides of the screen, and are extremely bright. LCD/LED TVs don't use much power, while producing better color than pure LCDs. Most LCD/LED TVs are also much thinner than regular LCD TVs, making them one of the best 70-inch TV choices for hanging from a wall or ceiling in bright rooms without much shade.
OLED: Organic Light-Emitting Diode (OLED) technology uses a panel made of thousands of tiny LED lights. This technology is considered organic because the molecules of the light-producing layer of the panel contain carbon. Buy a 70-inch TV with this technology if you want an HD-quality image regardless of your viewing angle. OLED displays work without needing a backlight, which means they can display rich, deep levels of black and can be lighter and thinner than LCD or LCD/LED models. This type of television is the best 70-inch TV for dark rooms or rooms with low ambient light.
Plasma: When you're looking at TV and video equipment, keep in mind that plasma TVs do not have any type of backlight. Instead, the plasma cells glow to illuminate the pixels for the television screen. Additionally, plasma TVs have high contrast ratios, and usually better motion resolution than other types of TVs. Top rated 70-inch TVs of this type are good if you play a lot of games or like to watch movies in a dark room.
>> Determine the inputs you need
When you buy a 70-inch TV, it's important to make sure that it has enough inputs and connections for all of your TV accessories. There are many different types of inputs, and the following chart explains the differences between them:
Input type Explanation HDMI This flat, thin connection has notches to show which way is up, and is the highest quality, most common and easiest way to connect external components to your 70-inch TV. An HDMI connection is digital to ensure there is no data loss or distortion. Additionally, it delivers both audio and video using one cable. The best 70-inch TVs have at least two HDMI inputs for various electronic supplies such as DVD/Blu-ray players and game consoles. Component This input type consists of a set of five circular ports. Three are used for video, and two for audio. Component connections are the best analog connections available, and they are the only way to get HD quality using an analog connector. If HDMI is not available, component is the next-best choice. When you buy a new 70-inch TV, ensure that it has at least one component connection, and more if there is only one HDMI connection. Composite Composite inputs are three round ports that are a bit bigger than component ports. One is for video and the other two are for audio. Composite connections, also known as RCA connectors, are the lowest-quality analog connections available, and can only be used for standard-definition video. If you plan on connecting a low resolution device such as a VHS player, make sure that you buy a 70-inch TV with at least one composite input. RF input An RF input is a circular, threaded socket that is used to connect the TV to an antenna source or a standard cable input. >> Consider sound options
Most top-rated 70-inch TVs have built-in speakers that offer adequate sound. However, you can choose to install a separate speaker system if you like surround sound, or simply better quality sound. The best 70-inch TVs have plenty of HDMI connections so that you can use one to connect a speaker system. However, if your speaker system does not use HDMI, or there are not enough HDMI inputs available, you can also use composite inputs.
A top-rated 70-inch TV should also include some inputs for external audio components such as MP3 players or AV receivers. The following chart shows the two most common audio inputs and outputs:
Input type Explanation Optical digital audio input A square-shaped port keyed with a top and a bottom. This type of port is typically used to connect the TV to an audio device via fiber optic cable. Audio output A round port that looks a lot like a headphone jack, used to transfer audio to and from devices such as MP3 players and mobile phones. Although this port is called an audio output, it also supports audio input. >> Do you want a smart TV?
Smart TVs are devices that can be connected to the Internet to access content such as streaming music and video. A smart TV can use many entertainment apps such as Vudu, Netflix, Hulu and Pandora. Many of the top 70-inch TVs are equipped with built in Wi-Fi or Ethernet connections in order to make use of smart TV technology. Many also include other inputs such as DVI or USB ports and memory card slots. This allows you to use your new 70-inch TV as a computer monitor, and view images directly from your mobile phone or digital camera.
>> Consider 3D TVs
3D technology is a feature offered on many new 70-inch TVs. In normal 2D viewing mode, these 3D TVs function the same way as any other TV. However, you can switch into 3D mode when you want to watch a 3D movie or television program. In order to view images in 3D, you need to wear special glasses. Without them, everything onscreen appears blurred. There are two types of 3D technology used in top-rated 70-inch TVs, active and passive:
• Active: Uses powered 3D glasses that are equipped with LCD shutters on each lens. When 3D content is shown, the lenses get darker to block each eye sequentially, in sync with the TV. Because one lens is blocked, only certain frames are shown to each eye. The frames shown to the left eye are moved a little horizontally compared to those shown to the right eye. This difference causes the 3D effect.
• Passive: This technology uses the same concept as active 3D except the glasses are not powered. Instead each lens is polarized to show video to only the right or left eye at any one time. Because of the many features available today, buying a 70-inch TV may seem like a daunting task. However, if you spend a little time deciding what features are important to you, you can find the best 70-inch TV for your entertainment needs.
