NEC and Hitachi have released recently, the Valuestar W, a silent computer that you want to replace the TV. Is it possible to do something like that, your TV to watch movies and soap operas on the LCD monitor of a computer.
However, we need to consider some technical points to not ruin the performance of your Media Centre.
First, it is essential that the user know that the visual outcome depends on the resolution. “The statement is to use monitors with higher resolutions,” advises the Division product manager of Samsung monitors, Paulo Gragnani.
Other details are important for the success of your media center. Gragnani gives the hint: “higher rates of brightness and contrast, as well as shorter response time.”
Check out what are these features.
Difference between TV and monitor
What differs a LCD TV of an LCD monitor? “The technology is the same, but the two work differently,” says the Director of new products from Proview, Wilkens de Figueiredo.
According to him, the TV tune card is responsible for capturing the transmission signal, convert it to a signal sent to the video presentation. In the case of the monitor, “the video is received following the standard VGA, and transmitted directly to the video presentation”, he adds.
Before anything, you will need a TV card. “She is usually attached within the PC, on a particular connector. However, you will need to do an adaptation to connect the antenna cable in this plate “, explains the Manager of the AOC, Audiene.
If you also want to watch movies with your new equipment, the ideal is to have a DVD player in your computer. “To connect a DVD player in your monitor, only if it has an RGB or DVI output-the same for video games. And this is not common, “explains the Manager.
“If the monitor does not have S-Video inputs, Component Video and Composite Video, that should be provided by a video card, the consumer will probably need to buy”, exposes Gragnani.
It is important to know that the reception of the signal will not change. According to Forbes, with a good resolution, it is possible to make video quality. However, “If the reception has noise-drizzle or ghosts, she will continue with the same problem,” he says.
This feature relates to the “life” of the image, the monitor’s ability to take the colors from white to black-IE define light and dark tones.
The higher the contrast ratio, more defined are the shades. “If the number is greater than 500:1, the monitor will have a good performance,” according to Audiene.
According to the Samsung Executive, “today, the TVs have dynamic contrast 15000:1 rates, and monitors arrive at approximately 4000:1.”
If you do not have the intention of seeing “ghosts” in the middle of a movie or favorite SOAP, the response time of your monitor should be of 5 milliseconds (ms).
Audiene explains that, “the shorter the time, the better the image in quick transitions, preventing blurriness in pictures of a lot of action and movement.”
Second Gragnani, the LCD TVs operate with 8 ms response time, while some monitors already work with 2 ms.
As its name indicates, what changes in this case is the brightness of the image. The minimum recommended so that your transmissions are not deficient in light is 300 cd/m ².
Gragnani reveals that “in the case of brightness, TVs take a little advantage because they operate with 550 cd/m ², while the monitors are in the range of 400 cd/m ².”
