what is vga and dvi
Difference Between VGA and DVI. Video Graphics Array or VGA and Digital Video Interface or DVI are the two methods of connecting your monitor into your computer. The main difference between these two is that VGA is an analog standard while DVI is digital. DVI is next logical step for connecting your computer and monitor. Video signals are originally digital signals but are converted into analog before leaving the GPU of your computer through the VGA port. VGA was created because all of the monitors at that time are based on CRTs which were analog in nature.
HDMI vs. VGA. VGA and HDMI are interface standards used for cables that connect devices â such as laptop computers and DVD players â to a display, like a TV, computer monitor or projector. VGA is an older standard that carries only a video signal. HDMI is the default cable standard for newer electronic devices, such as Blu-Ray players or LED TVs. HDMI can carry both digital video and audio signals, all while encrypting data with HDCP.
