The differences between VGA, DVI and HDMI.

With televisions, HDMI is the most common connector. But if you want to connect a computer to your TV (or you've got a new computer monitor), the options tend to be HDMI, DVI, and sometimes old-school VGA.

Let’s take a look at the good ole Video Graphics Array, better known as VGA.  VGA is a three row 15 pin connector, normally with a blue color plug.  VGA is an analog interface between a computer and monitor that was widely used before DVI was the standard.  Such devices that used VGA were some of the older CRTs monitors and some early LCD panel displays.  Though DVI is starting to become the standard in the majority of consumer computer products, VGA is still the standard in industrial type applications.  For example Caltron’s FBT-1503O Open Frame LCD Monitor are used in such applications such as POS systems, industrial machines, control panels, Kiosks, ATM machines and so forth.  VGA has been around for so long and is a reliable interface.

Digital Visual Interface (DVI) is a video display that transmit digital video and can be configured to support multiple modes such as DVI-D (digital only), DVI-A (analog only) or DVI-I (digital and analog).  It is used to maximize the quality of your flat panel LCD monitor and modern video graphic card, which now carry two DVI output ports.  DVI is the main stream input/output interface for the majority of the computer world.  Caltron offers DVI input as a standard with the LWT-2407O, 24 Inch 16:9 LED Open Frame Monitors with a 1920x1080 HD resolution.  With its HD resolution, with its DVI input interface, the LWT-2407O is a great fit for any application, whether it is just an open frame, touch screen monitor or digital signage application.

HDMI is short for High-Definition Multimedia Interface.  HDMI is a standard for all LCD and LED TV’s and most computer monitors and video graphic cards.  HDMI is like DVI except it is an all-in-one cable that gives that high definition picture/video and at the same time provides audio.  HDMI interface is heavily used in commercial and consumer products because of the need of high definition picture.  With the MP-1080N, Caltron’s digital signage players, utilizes the HDMI interface to output its content to display high definition videos and pictures and can be used in such places like galleries to showcase a photographer’s portfolio.

Though VGA is an aging standard, it is the norm in industrial type applications.  DVI and HDMI transmit digital signals and provide a more consistent image to provide High Definition content to consumers.
