Buy TV Collection: Price is not the only
Often consumers are used to buy television to concentrate on price, but the neglect of the product itself, some of the obvious features.
TV
As a family
Electricity
A big heavy head device, even with 50,000 hours of life, 8 hours per day, but also to use for 16 years, is definitely a consumer durables. Therefore, the purchase of TV before, especially on the last million flat-panel TVs at every turn, we must weigh thin, do not buy a home out of obsolete products.
Compatible format, the better the signal
Buy a new TV, not only compatible with the existing wired analog signal, but also compatible with digital signals, or simply whether the analog signal, it must be compatible with digital signals, analog signals
STB
Solution. While the new TV to be compatible with more digital signal standard, unlike analog signals, the standard simple identification, digital signal from the quasi-clear, standard definition, high definition, ultra high definition. But the standard range, it is recommended to at least support HD 720P, better able to support 1080i.
Interfaces to all
All terminal input and output signals is the basic TV channels, more terminal means more equipment with more standard format and under the Internet, shows the viability of television in the future. As Y.PB / CB.PR / CR component video input terminals, video input terminals, AV input terminals, high-fidelity
Headset
Output terminal, AV output and so is almost essential, and preferably has a pc input, high-definition video and usb interfaces PE Link.
Low resolution can not be
Can not support high-definition TV future core digital signal is one of resolution. Currently, the market
Sell
Most of the
LCD TV
Resolution has reached> 1024×768, to meet future high-definition requirements, but most
Plasma TV
Only 852×480 for standard definition resolution, can not meet the requirements of high quality. The proposed standard is 30 inches above the TV resolution to achieve> 1024×768.
Screen aspect ratio
It is understood that
Package
Including the sixth generation of LCD screen, not the seventh generation LCD
Cutting
4:3 screen, 4:3 screen on the market use the LCD TV is basically out of product, and 16:9 screen aspect ratio is also a necessary requirement for high-definition digital one. Meanwhile, the 4:3 screen times at the small-screen television, do not think it is a small screen, you can deal with what is most important is the 4:3 LCD TV must be out of product.
Brightness, contrast, viewing angle and response time
These points, in addition to a situation of virtual standard values will not have much problem, the brightness can not be less than 400nit, large-screen TV demand higher brightness; contrast, the higher the better, at least 500:1; 160 degree view in general, what should not be a problem; reaction time is particularly LCD TVs, said, only that you can not be greater than 16 milliseconds.
With the introduction of these points, I believe you will not be buying TV time spent on the yuan, also buy the product out to go home soon.
