Pay Attention to The Interface When Buy TV
Pay Attention to The Interface When Buy TV
These 10 kinds of video interfaces mentioned earlier, basically have been used in television except for three kinds(DisplayPort, IEEE 1394, BNC), and some TV sets may even have all of these seven kinds of interface, as a wise consumer, How we treat these interfaces when buy TV. To connecti with other electrical in the family, which interface is a must have one? Which interface is after elimination, and commonly less used out? Here we discuss these interfaces in three types.
1, RF, composite video and S-Video
These three interface developed along with the early analog TV technology, can only transmit "SD" video, which are essential in the era of CRT TVs, otherwise there is no way to watch TV, connect VCD, DVD machine. But now LCD TV has been so popular, and the cable television in family has access to digital set-top boxes, these interfaces have been largely useless.
From another point of view, we must guard against is that, with the "high-definition" concept of the popular now, many audio and video products promoted under the banner of the name of high-definition , which are bound inside some unscrupulous businesses, sold "SD" products in "high" price, how to judge it? There is a basic approach is: If this product's video input and output only these three kinds of interface (Part One), then this product must not support high-definition signals, the video display or output definitely not achieve the high-definition standard.
2, Chromatism
Chromatism interface is transfer analog video signals too, but the chromatism inputs support from the standard definition (480P, 576P) to HD (720P, 1080i, 1080P) video signal, so the basicly the DVD in the market are the preferred chromatism interface output, so we need to pay attention when buying TV, as far as possible to have this interface.
3, VGA, DVI and HDMI
These three interfaces are all high-definition interface, especially the HDMI interface, has been promoted as the only high-definition interface by the major TV manufacturers, seems as long as have a HDMI interface, the television immediately become a high grade! In terms of its
real effect actual use, the effect of DVI and HDMI is the same, VGA effect somewhat less certain, but this gap is not evident, especially work in resolution of 720P (1280X720), the three interfaces should not see any difference.
Taking into account fo the true high-definition products is gradually increasing, especially now that the LCD TV display resolution has been achieved even more than a computer monitor, you can easily connect the computer and television form a "high-definition" home theater, so we strongly recommended to purchase an LCD TV, be sure the TV has VGA, DVI and HDMI interfaces, especially the HDMI interface, the more the better.
