TVs and monitors of various models and also screens of laptops and netbooks differ from each other in diagonals of screens. It is necessary to choose the device in this parameter depending on the purposes in which it will be used.
Instruction
1. Consider that the power consumption of the TV and monitor depends on screen diagonal not linearly. With increase in diagonal twice the area of the screen, so, and the power of the device increases four times. Therefore replacement of the pipe TV or monitor on liquid crystal, but much larger, sometimes is capable to lead not to reduction, and to electricity consumption increase.
2. For the laptop which is planned to be used as in stationary conditions and on the way, the screen with diagonal about 15 inches in the best way approaches. On the one hand, on it to read text is rather easy, without straining, and with another - it is rather convenient to transfer it. It is better to choose the netbook which is calculated on constant carrying similar to the smartphone with screen diagonal in 7 or 10 inches - it is easy and rather slowly spends energy of the battery. The laptop consumes from 50 to 90 watts, the netbook - about 30.
3. To the desktop computer buy the 19-inch liquid crystal monitor. Larger devices spend much more electric power, and less large - are laid off. If on a table you have not enough place, buy the second-hand 15- or 17-inch liquid crystal monitor. All of them consume from 30 to 50 watts. It is undesirable to use together with desktop computers pipe monitors, especially to people at whom from blinking eyes strongly get tired. Besides, they consume 70 and more than a watts.
4. In kitchen, in the bedroom the pipe or liquid crystal TV with diagonal, respectively, in 14 or 17 inches is good. It is rather compact for placement in the small room (for example, on the fridge or a bedside table), and the audience who is at distance to three meters from the screen will be able to watch it with comfort. Consumes such TV from 35 to 60 watts. If color is not necessary to you, the black-and-white pipe 12-inch TV with a power consumption about 25 watts will approach.
5. To the living room the 14-inch TVs put seldom. More often in it devices with the screen of 20 in size and more inches consuming from 50 to 90 watts have. Consider that at diagonal over 35 inches unreasonably high power (100 and more than a watts) is consumed even by liquid crystal TVs. Use of the device with LED illumination of a matrix which has a relation power per unit area of the screen much less will become an exit in this case.
6. Plasma TVs are issued with diagonals from 40 inches. They consume from 300 to 500 watts. Their owners are recommended to keep the second, ordinary TV in the same room and to watch on it the news and other telecasts which are not demanding the large screen, and the plasma device to include only for viewing feature films.
7. If the TV directly is located on a table at which the viewer sits, his diagonal has to be small - from 4 to 10 inches, differently will be inconvenient to watch it from small distance. Color TVs of such sizes are issued only in liquid crystal execution today, and black-and-white - only in pipe. They consume from 5 to 20 watts.
