Guide to the selection of televisions, including HD, high definition and flat screen
ByTechnology in all areas of our daily lives has become increasingly present and especially more advanced, but one of the most developed and attractive appliances at the moment is definitely the TV.
Gone are, in fact, the times of old, bulky and heavy CRT TVs, which often gathered the family for the program’s flagship prime time, costs have now been killed, and in almost every room if they can find one .
At the expense was certainly the cinema, which has lost a considerable market share over the years, with new technologies that have made the images on the small screen above, in some cases, those of the projection rooms.
What’s more, the advent of digital television has made the last, strictly flat and light, real jewels, which lost in super-realistic images and sharp beyond belief.
But as directed in this rich and complicated world? First, we need to know the latest terminology, such as HD, which stands for High Definition, including virtually all TVs have the latest, in particular, the HDTV has a resolution of 1280 x 720, twice as much as traditional ones. But we are already at full HD, launched recently, which has even a resolution of 1920 x 1080, almost four times greater than DVD.
And the DVD, both as optical media as a reader, are likely to retire soon: Sony, in fact, has created and marketed the Blu Ray disc, which uses a blue laser precisely and whose records may contain up to 54 Gb, about 10 times more than the dual-layer DVDs.
To get the maximum, in short, we provide the combination of HDTV and Blu Ray. But really worth it?
Safe for addicts and fans of technology, items are missed, despite the costs are still quite high, but for ordinary viewers, who spend hours watching TV and especially without much involvement, are probably wasted.
So we must properly evaluate the cost and its requirements before deciding to make the big step towards high definition, definitely putting retire on dear old conventional TV.
