What is DVI?

DVI stands for digital video interface. It is a video connector that enhances the images viewed on digital projectors such as LCDs. DVI is designed by DDWG or Digital Display Working Group.
When CRT was still in vogue, VRG or Video Graphics Array was used, and is still used. This technology works by transmitting each horizontal line of the image. The voltage output is different to reflect the different levels of brightness.

DVI works very differently from VRG. The level of brightness of each pixel is transmitted into a code in binary form. Not using analog signals, there is no noise or distraction. The format of data is of Panel Serial Format. This format uses TMDS or Transition Minimized Differential Signaling.

Each link of DVI has four pairs of wires that are twisted. These wires enable a transmission of 24 bits per pixel. A single link gives a maximum resolution of 2.6 megapixels for 60Hz. A DVI HDTV Connector may be used to connect another link should a higher resolution be required. In fact, the same DVI HDTV Connector may use digital and analog transmissions. DVI HDTV Connector may be categorized into:

1. DVI Digital
2. DVI Analog
3. DVI Digital and Analog

In contrast, open LDI and LDVS are based on digital technology exclusively. These are also the main competitors of DVI.

DVI is a useful technology that you can find in the video cards inside computers, in DVD players, etc. The improved technology of this one is compatible with a high bandwidth and can display images easily. This technology is resonant with quality and ease of usage, the most important factors in the world of today.
