Nowadays, technology enhancements in video signal transmission have ensured analogue and digital signals are transmitted using different devices. For instance, there are several types of VGA to DVI Splitter on the market to select from for video duplication.
The decision must be canvassed thoroughly before buying a VGA or DVI video splitter. Therefore let's outline what VGA and DVI are, as well as the timeline they were both released.
Video Graphics Adaptor (VGA) technology has been available since 1987 thanks to IBM for development of this analogue video display technology that went onto become a standard used when referring to analogue video display standards.
VGA hardware and the software enable the data processed to become graphical data that can be displayed on a display monitor. The actual resolution for VGA is set at 640 x 480 pixels in display resolution for width and height respectively. However VGA display resolution has been enhanced with higher video resolutions such as SVGA, XGA and UXGA et al. In addition, the majority of manufacturers and resellers still refer to a Brand VGA splitter, even though VGA has higher analogue video resolutions available, such as mentioned early like SVGA, XGA and UXGA.
Digital Visual Interface (DVI) is a newer technology that was released in 1999 by Digital Design Working Group. The key feature about DVI is its compatible with VGA. The two video interfaces work well with one another when an adaptor is utilized.
DVI can stream digital video very well however it can't transfer audio signals. To enable audio on a DVI splitter you'll require digital audio capability built-in to the devices with separate audio connections. Furthermore, the release of High-Definition Multimedia Interface (HDMI) technology that can transmit uncompressed digital video and digital audio signals together has ensured HDMI quickly became the popular choice for digital video output to display panels.
When selecting a DVI or VGA splitter ensure you check the specifications for the product, for example resolution supported, frequency rate, the display video type supported, connection types for interface input/output, power adaptor required, switching off/on functions, built-in amplifier booster and whether incorporated with audio socket or not.
Moreover, VGA Audio Splitter has generally been more popular with computer display monitors over the years than DVI. The cost for a VGA splitter is usually less than its equivalent DVI product. Furthermore with the popularity of the superior HDMI technology integrated into high-definition TVs and notebooks has ensured DVI splitters are less common. With most people selecting a HDMI splitter for their digital video and audio solutions over the less-features of DVI.
Whether working with analogue or digital video signals a VGA Splitter and DVI Splitter can significantly enhance the intended audience visual experience. These devices allow numerous benefits with computer display monitors and audio visual installations.
