Black Box Explains…Digital Visual Interface (DVI) connectors.

The DVI (Digital Video Interface) technology is the standard digital transfer medium for computers while the HDMI interface is more commonly found on HDTVs, and other high-end displays.

The Digital... more/see it nowVisual Interface (DVI) standard is based on transition-minimized differential signaling (TMDS). There are two DVI formats: Single-Link and Dual-Link. Single-link cables use one TMDS-165 MHz transmitter and dual-link cables use two. The dual-link cables double the power of the transmission. A single-link cable can transmit a resolution ?of 1920 x 1200 vs. 2560 x 1600 for a dual-link cable.

There are several types of connectors: ?DVI-D, DVI-I, DVI-A, DFP, and EVC.

  • DVI-D is a digital-only connector for use between a digital video source and monitors. DVI-D eliminates analog conversion and improves the display. It can be used when one or both connections are DVI-D.
  • DVI-I (integrated) supports both digital and analog RGB connections. It can transmit either a digital-to-digital signals or an analog-to-analog signal. It is used by some manufacturers on products instead of separate analog and digital connectors. If both connectors are DVI-I, you can use any DVI cable, but a DVI-I is recommended.
  • DVI-A (analog) is used to carry an DVI signal from a computer to an analog VGA device, such as a display. If one or both of your connections are DVI-A, use this cable. ?If one connection is DVI and the other is ?VGA HD15, you need a cable or adapter ?with both connectors.
  • DFP (Digital Flat Panel) was an early digital-only connector used on some displays.
  • EVC (also known as P&D, for ?Plug & Display), another older connector, handles digital and analog connections.

    Black Box Explains... Digital Optic Cable

    Many new, high-quality Mini Disc, pro-audio, DAT (Digital Audio Tape), CD, DVD, and laser disc players, as well as digital amplifiers, DSS satellite receivers, and computer sound cards, are manufactured... more/see it nowwith digital optical output connectors.

    These connectors attach to optical cables, which are constructed with a PVC jacket and a plastic core. The cables transfer information accurately over short distances via digital light signals with low loss and no distortion.

    Digital optical cable with plastic-core construction is less expensive than fiber optic cable with a glass core, but it still provides the benefits of optical transmission over short distances.

    Digital audio makes it possible to use high-quality digital-to-analog converters, which help to maintain the integrity of sound signals from high-end electronic devices.

    The two types of connectors associated with digital optical transmission are TOSLINK®, a Toshiba® trademark, and the 3.5-mm Mini Plug connector. collapse

    • Video...MediaFlyer™ demo: How to use this Web-based platform to set up impressive digital signage on the fly.

      Hosted by George Borden, Digital Signage National Sales Manager for Black Box, this video shows how simple it is to create digital signage using MediaFlyer™, our SaaS-based solution for monitoring... more/see it nowand managing single-screen or a multiscreen deployments. In the demo, he discusses the many media formats supported by MediaFlyer, as well as its number of preloaded apps for taking advantage of content feeds from YouTube®, Flickr®, Picasa®, and other external sites. The video also explains the role of the player (the only hardware required for the system) and shows how the system operates, walking you through its easy-to-use, Web-based interface for loading content, creating layouts, and populating layout zones with content. He then demonstrates how simple it is to assign content for display using the system’s schedule editor function. collapse

    Black Box Explains: M1 connectors.

    In 2001, the Video Electronics Standards Association (VESA) approved the M1 Display Interface System for digital displays. The M1 system is a versatile and convenient system designed for computer displays,... more/see it nowspecifically digital projectors. M1 supports both analog and digital signals.

    M1 is basically a modified DVI connector that can support DVI, VGA, USB and IEEE-1394 signals. The single connector replaces multiple connectors on projectors. An M1 cable can also be used to power accessories, such as interface cards for PDAs.

    There are three primary types of M1 connectors:
    –M1-DA (digital and analog). This is the most common connector, and it supports VGA, USB and DVI signals.
    –M1-D (digital) supports DVI signals.
    –M1-A (analog) supports VGA signals.

    The M1 standard does not cover any signal specifications or detailed connector specifications. collapse
