Analog vs. digital video signals

Technology advances, so do our expectations of them, this seems only to create some of the speed of technological progress. In some cases it is possible for a temporary stop to make progress, like all others obsolete. This is the problem of digital vs. analog video signals.

It may seem a small thing, but the need for universal solutions to ensure compatibility between the systems has resulted in the presentation of computer graphics than the rest of the delayInformation Technology. Until about 2002 video images were similar, ie, had some inherent limitations due to show the amount of information could be transmitted to the monitor. The most obvious effect of this is that there is some pixelation in the display, if you look closely you can see pixels. Pixelation with digital graphics, but most is eliminated. This is most evident when comparing VGA vs. HDMI, simple, high-definition television on the phone to compareTo see the difference, the phones tend to block the formation and the simple graphics and even video signals are some pixelation, while the use of digital HDTV signals are very clear.

Of course it is very obvious when the conversions are attempted from VGA to HDMI. It's not that (HDMI) digital system is bad, is that the analog (VGA) system is dated and shows age, VGA has a limited range, and limits the definition that simply can not the digital version does not exist, andthese limits are readily visible when the translation is attempted. It does not help that we used for the digital system, which were most computers since 2002 has been moved to above or to the digital standard. Although you can adjust the signal, there are some artifacts in the signal. All in all, HDMI is a big improvement over VGA, and it shows.
