A video graphics array (VGA) was originally a graphic display system that was developed by IBM for PCs. It actually refers to the display hardware that was introduced with IBM’s first line of computers back in 1987. VGA, although now obsolete, most often refers to computer graphics. However rather than viewing the graphics on your PC or laptop, many people take advantage of a VGA to TV converter. There are many reasons that you may wish to view certain graphics on a TV screen as opposed to a PC screen and these may include:
Many computer professionals make use of VGA to TV converters especially in the production of computer animation and various educational computer video tapes. You should not immediately assume however that the image produced by your TV will be just as good as your PC monitor. This will very much depend on the quality of both the converter and your TV. Typically the better your TV is, the better you can expect the graphics and image to be. Unfortunately though a TV screen will never give you as sharp a picture as a PC as their technology is completely different from each other. A converter will be required to filter the picture in order to completely avoid any flickering. You will also find the bright colors and images appear far clearer and better on a PC as opposed to a TV.
One form of VGA to TV converter is a scan converter. This will allow you to simultaneously display the images on your computer monitor directly onto a television or you may even record it to video. The most common use of a scan converter is typically during a business presentation. A laptop can be connected up to the scan converter unit and your presentation can be displayed onto a large screen TV. Basically a scan converter will take whatever is on your computer screen and direct it straight at your TV.
For many years apart from PowerPoint presentations or watching a video or DVD, there was no real reason to convert images from your PC screen to your larger TV screen. There were also many technical issues to take into consideration such as computer graphics (VGA) and normal television are extremely incompatible. Video signals that you usually watch on your TV screen are composite, whereas PC graphics and the picture signal they receive is analogue RGB signal. So unfortunately this would mean a lot of work and plenty of conversion is needed.
Since the inception and availability of live video streaming however, manufacturers now has an extremely compelling reason to produce VGA to TV converters. You should find that the majority of these types of converters come in a connector and cable set. The cable will be used to carry analogue video signals and data from the displaying graphics. A VGA that is found on laptops and other similar devices is typically a 15-pin connector port. You must first plug the VGA cable from the source straight into the converter, and then use either an S-Video or RCA cable to attach to the TV. There is no need to carry around an external power adapter as the converter will be USB powered. Therefore, you could say, that connecting a laptop to a TV is completely portable.
The more recent innovations in computing technology have made the VGA to TV converter far less fussy than it ever used to be. You can now get high-resolution VGA display up to 1280 x 1024 and the majority also have an advanced frequency modifier which will ensure that your picture or image is completely flicker-free. These converters are far less complicated than the models used a decade ago, you can literally plug it in and play. You will also find that the converters are very light and compact which will make installation far quicker and easier. It is extremely important before you even consider purchasing a VGA to TV converter that you check to make sure that your PC and its VGA card has a TV-out function capability.
