DVI-I to DVI-D Cable or DVI-D to DVI-D Cable?


Maybe I can clarify a little. DVI-A (Analog) and DVI-D (Digital) both use the same connector but diffrent pins to transmit the signal. A DVI-I cable is a DVI cable with both the analog and digital pins. (so if you plug it into an analog device it will function as a DVI-A cable, vis versa if you plug it into a digital device it will function as a DVI-D cable). DVI-A and SVGA are one and the same, just a diffrent connector type. Most video cards (if not all at this point) have DVI-I connectors on them giving you the choice to use either analog or digital (you choose by pluging in either an analog or digital cable). This leaves most people thining a DVI-I cable will be the right cable since it does everything, but in reality it doesn't always work this way. Lots of Digital devices will not leave the pin holes for the DVI-A connection (I assume this is to make sure the user uses the proper cable). So while in theory a DVI-I should work, in real life it will not. This is why we reccomend customers buy the proper cable for the application rather than a "one size" fits all. Hope this clears up some confusion. You can always take a look at http://www.dvihdmicables.com/ - Lots of good info there. DVI-D to DVI-D is the cable to use.

DVI-I Dual Link to HDMI?

Customer Question - "Hello. I'm trying to connect my LCD HDTV to my computer, so that I can use the TV as my monitor. The problem I'm having is figuring out what kind of cable I need. I know I need the HDMI to go into my TV, but I can't seem to find a cable that has DVI-I Dual Link on the other end. Do I need to link or is that optional? I'm kind of confused . I'm using DVD-I Dual Link going into my computer now from my LCD monitor." This is a very common customer question. While it may seem quite confusing the answer is rather simple. When the video card manufacturers produce video cards they want to make sure the video card will work with as many displays as possible. Since there are such a wide variety of displays availble now days most video cards ship with a DVI-I connection. This DVI-I (intergrated both analog and digital) connection will allow you to connect a analog SVGA (with adapter) or analog DVI-A cable to the port to support most analog monitor types. The DVI-I connection also allows you connect digital devices using the DVI-d cable or HDMI (with adapter). The DVI-D to HDMI connection is always a single link connection. So while you may have a DVI-I connector on the video you really need a DVI-D Single link to HDMI or DVI-D Cable to connect your pc to your HDTV via a HDMI or DVI port.
