Modern display devices offer a variety of functionalities, and slight modifications can be made to the output of your electronic devices to ensure your VGA devices and separate video devices can communicate with one another for maximum utility.
A video graphics array, or VGA, is the de facto standard graphics display for computers. Initially developed by IBM, a VGA systems provides resolution of 720 x 400 pixels for text mode, 640 x 480 for 16 colors in graphics mode, or 320 x 200 with 256 colors in graphics mode. While some modern computers may offer more advanced graphics display, all models will support standard analog VGA.
Separate Video, commonly known as svideo, carries an analog signal through two separate wires to an output device. Svideo operates with standard resolution, which is typically 480i or 576i, and audio signals are carried on a separate cable. Svideo is the standard type of output for most non-HD televisions, and HDTV will generally support this type of cable as well with lower picture quality.
As computers and televisions have different graphical display options, a VGA to SVideo adaptor is needed to view computer output on a television, or to view television output on the computer screen. This will typically require a special cable or adaptor to have the picture view appropriately.
The vga to svideo cable operates with offering the appropriate plug type for each component piece. The VGA plug is identical to those utilized to connect a standard monitor, and has 15 identical pins places in three rows. The svideo cable is identical to those used to connect many DVD players and gaming systems; the plug typically has four circular holes for the svideo pins and square opening at the bottom of a circle. A converter may be necessary for users who do not have the appropriate graphics card to use a cable converter only, and the converter will frequently work with composite cables as well to allow the maximum flexibility for the consumer. When using a converter box, the consumer will still need the appropriate cables to connect devices.
Some common uses for vga to svideo applications are instances where a user needs to amplify items shown on the computer screen onto a television. For example, if a doctor needs to view a higher quality or larger picture of a medical document that has been emailed, by displaying the computer screen’s contents on a 32 inch television will allow for greater ease of viewing the picture, and higher details on smaller areas.
An additional advantage includes an easy method of recording web conference training sessions. By allowing the computer content to show on a television, a user may make a DVD or VHS recording of the event to keep on file for future training sessions or for the user’s personal reference. A final reason a user may elect to transfer the VGA display to a svideo application would be to use computer software as a temporary stand-in for home theater equipment. For example, if a homeowners DVD was not operational, but the laptop computer has the capability of playing DVD’s, by allowing the laptop to display on the television, the homeowner is able to enjoy their DVD library with no interruption.
Once set up, converters are very easy to use, but it may be a little confusing to determine the correct converter for you. By writing down the specifications of both the VGA graphics card and the TV output options, you may ask a computer or television installation professional how to ensure the electronics communicate properly for the easiest to install, highest picture quality option.
Quick Tips For Converting VGA To Svideo
When choosing the correct VGA to svideo option for you, it is important to consider the existing graphics card, television output requirements, and picture quality desired. By determining the options available, you may determine the correct vendor and resource for your uses.
The first option is a VGA to SVideo cable. Most adaptors work with G400 and NV6 or higher video cards with a TV-Out function. It is important to know the specifics of your graphics card, including make and model number, when confirming the purchase of the cable. Cable manufacturers will list the specifications of the VGA cards they work with, and can confirm if the product will work on your machine. However, regardless of the graphics card, if it is not tv-output enabled, the cable will not be sufficient alone. VGA to Svideo cable options are available in a variety of lengths from five inches to fifty feet, and prices will be higher for longer cables. Apple users may need a special brand to ensure the graphics are correctly transferred to the svideo device, but are fortunate in that according to Amazon.com the Apple vga to svdideo cable has received the highest user ratings. For PC users, the favored brand is HDE, and generally is lower in price with higher selection of lengths than the Apple option. It is worth reiterating when selecting this VGA to svideo choice, the computer must be equipped with a tv-out function or the cable will not work. Bear in mind, many vendors do not allow returns of specialty adaptors and cables, and the consumer should verify the cable will work prior to purchase.
If the computer is not equipped with a tv-output function, you will need to purchase a VGA to svideo converter. Converters are typically quite small, portable, and easy to install. The vga to svideo converter performs the same functions as higher end graphics cards and translates the VGA signal for viewing on the standard video application or visa versa. The converter will select the type of picture quality available, and this will vary according to both machines being used; most converters are capable of automatically adjusting the picture, but manual corrections may also be made. Prices generally range from $20 to $90, and excellent choices are available at any price point. Some popular brands include StarTech.com and VideoSecu. Apple users will again need to ensure the vga to svideo converter is functional for Apple products.
For individuals who had an HDTV, the vga to svideo option may not be ideal. Newer high definition TV’s commonly use an output called HDMI, and many VGA HDMI converter options area available. Due to the bandwidth required for HDMI picture quality, the converter must process a higher amount of information, and prices are higher. The Startech.com converter is commonly held as one of the most popular VGA HDMI options, and starts around $175. The converters allow translation of the analog VGA signal to HDMI digital signal in resolutions of up to 1080p for HDTV input and 1600 x 1200 PC input.
By determining the quality of picture required and the equipment already owned, you may easily select the correct VGA to svideo connectors for your needs. While the initial cost of ownership may seem expensive, most users find applications they had not originally anticipated upon purchasing. For those seeking feedback prior to making a commitment to purchasing a converter or cable, online forums and user reviews are available at Amazon.com, BestBuy.com, and Afterdawn.com. If you are not certain about obtaining the specifics of your graphics card, you may wish to contact your computers manufacturer and ask for assistance. The manufacturer customer service line will need to know the make and model of your computer in order to properly guide you as to the factory installed features.
