Picture size is measured in inches.
An inch is 2.54 cm. The size of the screen is measured diagonally from corner to corner.
What technology is the TV based on?
Tube- The tube TV has almost disappeared from the market giving room for the more slim plasma and lcd. The main disadvantage with tube technology is that most tubes are fairly cumbersome, so these types of TVs generally take up quite a bit of space.
Plasma tvs are thin and lightweight and capable of being mounted on a wall like a painting. Their main advantage toward LCD is that they are capable of showing a more intense black.
LCD stands for Liquid Crystal Displays. It is a flat panel technology which uses liquid crystals sandwiched between two glass plates. These TVs can be even thinner than plasma screens and they normally use less energy. LCD-technology is the most common technique today.
LED-tvs are newer versions of LCD-tvs that use light-emitting diodes as backlight. This allows them to show black and dark colors more intensively.
Projection-TV use three picture tubes instead of one. A red, a blue and a green cathode ray tube. The advantage is that you can easily project to a large surface area without too much loss of quality. One disadvantage is that it is still very expensive to buy.
This is a way to measure how many lines, or pixels, a TV shows.
4K Ultra HD is the future resolution. It has 4 times the resolution of Full HD. Resolution is at least 3840x2160 up to 4096x3112.
1080p b> and 720p b> is also known as HDTV. The number represents how many horizontal lines the image contains. 1080p resolution is 1920x1080 pixels, and 720p is 1280x720 pixels.

|Motion Frequency Rate||600 Hz|
|Energy Efficiency Class
Manufacturers of TV's must declare the energy efficiency of their products, using an A to G scale - A being the most energy efficient. The label must be clearly shown on the TV set.
|Power Consumption (In use)||90 W|
Indicates the sound effect.
For example, 2x10W means that the model has two sound channels with a power of 10 Watts each. Watt - in short, the measure of the amplifier's power.
The year in which the TV manufacturer has released the product into the market. Usually the same year as its available in stores.
High Definition Media Interface. A type of connection for connecting Digital Video and Audio.
(Universal Serial Bus) A widely used hardware interface for attaching peripheral devices. USB ports began to appear on PCs in 1997, and Windows 98 was the first Windows to support it natively. Within a few years, USB became popular for connecting nearly every external peripheral device. Replacing the serial and parallel ports on a PC, at least four USB ports are standard on every computer.Hot SwappableUSB devices can be connected to without turning the computer off, enabling removable devices to be plugged and unplugged as needed. This feature, combined with easy-reach ports on the front of the computer case, gave rise to the ubiquitous USB drive.USB 1.0 and USB 2.0USB has a maximum bandwidth of 12 Mbps for USB 1.0 and 1.1 and 480 Mbps for Hi-Speed USB 2.0. Up to 127 peripheral devices can be attached to the bus, and USB 1.1 devices can plug into USB 2.0 ports. Fast devices can use the full bandwidth, while low-speed ones can use a 1.5 Mbps sub channel.USB HubsA USB hub provides additional ports for the user. Like any other USB device, the hub plugs into a USB port on the computer and provides four or more USB ports for peripherals. The peripherals themselves may also contain hubs. For example, a monitor may have a built-in USB hub in order to provide a convenient desktop location for plugging in other devices.Type A and B, Mini-A and BThe USB ports on computers and hubs have a rectangular Type A socket, and peripheral devices have a cable with a Type A plug. Peripherals that do not have an attached cable have a square Type B socket on the device and a separate cable with a Type A and Type B plug.The Mini-A and Mini-B connectors are used on small portable devices such as PDAs, music players, digital cameras and cell phones. Hubs may use Mini-B instead of Type B for the computer connection.
