Funnet på nettet (google):

DVI connection can be one of three types - DVI-I, DVI-D or DVI-A.

DVI-I:

DVI-I contains both the digital and analog connections, (DVI-D + DVI-A) , it's essentially a combination of DVI-D and DVI-A cables within one cable.

DVI-D:

DVI-D (like DFP or P&D-D (EVC)) is a digital only connection. If both devices being connected support a Digital DVI connection (DVI-I or DVI-D compatible) and are compatible in resolutions, refresh rates and sync, using a DVI-D cable will ensure that you are using a digital connection rather than an analog connection, without playing around with settings to assure this.

DVI-A:

DVI-A is really rare. Why use a DVI connector when you can use a cheaper VGA connector? see DVI-I P&D-A (EVC) is more common with projectors, and you should go to your projector manufacturer for recommendations.

Dual Link: Dual T.D.M.S. (transition minimized differential signaling) "links". DVI can have up to two TMDS links. Each link has three data channels for RGB information with a maximum bandwidth of 165 MHz, which is equal to 165 million pixels per second. Dual-link connections provide bandwidth for resolutions up to 2048 x 1536p.

Single Link: Single T.D.M.S. link. Each link has three data channels for RGB information with a maximum bandwidth of 165 MHz, which is equal to 165 million pixels per second.

Bandwidth for a single-link connection supports resolutions of over 1920 x 1080 at 60 Hz (HDTV).

Dual link vs Single Link: Don't believe the "hype" some websites are using about dual link cables being superior to single link cables. A single link cable is 100% as good as a dual link cable for single link equipment which covers about 99.5% of current equipment, including HDTV's, Projectors, Plasma Screens, and High Definition Set top Boxes. A better quality cable is a better quality cable, and single and dual link has nothing to do with quality. On the other hand, if both devices being connected support Dual links, then a dual link cable is the proper cable for the application, and you will have the capability of much greater resolutions and refresh rates. A properly designed Dual link cable should have no negative effects when used with single link equipment.

Jupps, enig meg ham over - DVI-I bærer både digitale og analoge signaler - hvis DVI-I er en fordel hvis du vil ha muligheten til å koble til gamle skjermer som ikke støtter DVI-D.

 

Men i dette tilfellet er det jo bortkastet - ettersom det allikvel er en 15pin VGA kontakt på - med mindre du vil kjøre en dual screenløsning med 2 stk skjermer som skal kjøre på analoge signaler.

 

edit: han over var p.t. : BrAtTeRn :D

sakset fra wipipedia.org:

 

DVI-D (digital only)

DVI-A (analog only)

DVI-I (digital and analog)

 

Det vil vel i praksis si at man ikke kan koble til analoge skjermer på en DVI-D utgang (i motsetning til DVI-I). :)

 

edit: whops, litt sen der ja :roll:
