Using DVI monitor with desktop PC

Posted on 2006-04-21
Last Modified: 2010-04-26
Client is requesting 21-24" LCD monitors and am considering recommending the Dell DVI WUXGA 24".  I've not used a DVI monitor before.  What should I be looking for in the way of compatibility and what kinds of problems might I expect?

    DVI monitors just use a different connector from the the analog VGA one.  The advantage is an all digital path from video card to display, which definitely makes it sharper on large screens, but is not as evident on standard sizes.  The DVI connector comes in DVI-D (digital only), DVI-A (analog only) and DVI-I (integrated, meaning it has both).  For the most part, you don't have to worry about which one the monitor has because video cards put out DVI-I, which is usable by both digital and analog connections.  The Dell widescreens are very nice quality monitors and I would recommend them also.

    See about the different types of connectors and what they look like.

    To focus on your precise questions:

    "... What should I be looking for in the way of compatibility ..." ==>  as Callandor noted, there shouldn't be any.  HOWEVER, to state the obvious (which hasn't been mentioned here) -- be SURE the video cards on the systems have DVI outputs :-)

    "... and what kinds of problems might I expect?" ==>  Most likely none; BUT again, there is one area that you should check:  be sure the video drivers for the systems support wide screen resolutions.

    One other more significant issue you need to be careful of -- not a problem with the 24" display you've noted above, but as you start getting into large widescreen displays (the 30" Dell or Apple Cinema for example) you may require a dual-link DVI video card.

     Bottom line:  the display you're looking at is excellent and your client will be happy I'm sure.   Just be sure you have (a) a DVI output on the video card; and (b) drivers that support the widescreen resolution of the monitor.

    ... this place needs a "preview" button !!  ... end of my first line should be "... shouldn't be any issues."

    Make sure you take a look at the connector on the PC side:

    1) If you have two groups of 9 pins on the left side of the cable, you have a single link connector
    2) if you have 1 large group of 12 pins, you have a dual-link connector

    3) If you have a horizontal line on the right side of the connector, you have a DVI-D connector
    4) If you have a horizontal line and two pins on the top and two pins on the bottom of it, you have a DVI-I connector
