All existing interfaces differ from each other in three primary parameters: the type of transmitted signal (analog or digital), the maximum supported resolution, and bandwidth. Of course, there are many more parameters, but these three give a basic understanding of what this or that interface can do.
In the competition between analog and digital interfaces, the latter has long won a convincing victory. The digital signal reaches the output device without much distortion, which allows you to get a high-quality picture without interference. Besides, any modern video card initially outputs only a digital signal, and its conversion to analog – and on the monitor, unless, of course, we are talking about electron-beam antiques, again in digital – leads to a significant loss of quality. However, the analog connection still takes its place in the sun today.
In terms of bandwidth and resolution, the two are closely related. The higher the bandwidth provided by the interface, the higher and the maximum image resolution. If someone does not understand what we mean by the term „bandwidth“ now, then we explain the number of bytes of information that the interface can transmit to the monitor per second after receiving a signal. It is evident that interfaces designed to ensure widescreen monitors and LCD / plasma TVs with their high resolutions must have high bandwidth.
First of all, 4K2K content is crying now. Therefore, it will be challenging to enjoy native resolution anything other than the demos that come with your expensive TV set. To do this, many manufacturers put a special chip that allows you to stretch FullHD content up to 4K2K using unique algorithms: maybe not as excellent as 4K2K live broadcast, but very, very good for upscaling. Ask any GT user who owns such a TV – they won’t let you lie.
Secondly, there are two different types of 3D – passive and active glasses. In the first case, the content gets interlaced, and polarizing glasses, inertia, a bright picture, and an exciting movie make you forget that half-frames are coming with „dishonest“ resolution. In the second case, the doubled frame rate is used, and here the main problem awaits us: not all video interfaces can transmit a FullHD picture with 48 frames per second.
Modern connection methods
It would help if you started your overview of the primary interfaces used with VGA Cables on Jiji Nigeria. It is the oldest mass interface type in use today – it was developed already in 1987. Since then, however, it has been somewhat improved following the development of monitors.
It is the only analog interface still actively used today – its counterparts S-Video, YPbPr, and digital-to-analog SCART are no longer found in new modern devices. Almost all major computer makers are planning to ditch VGA altogether this year. It simply has no advantages compared to other types – it is a morally and technically outdated standard that is about to disappear from the market.
