DVI-I vs. DVI-D

[thefish8]

I just got a Viewsonic VP2000s, and it didn't come with a DVI cable. The specs said that the conector is a DVI-I conection for digital. I purchased a DVI-I cable and it doesn't work. Do I need a DVI-D? What's a DVI-A connection? Thanks in advance for anyone who helps.

It should work for you I think.

Does your monitor have an option to switch between VGA and DVI input? Anything about it in the manual?

 

[thefish8]

Yeah, I can switch to DVI-A, DVI-D and D-SUB (VGA). Is there any configuration I am missing out on? Thanks.

Quick lesson:

DVI-I: Carries both a digital and analog signal
DVI-D:Just a digital signal
DVI-A: Not an official standard, it is the nanlog portion of the signal that the DVI-I cable carries.

Your video card is putting out a DVI-I signal, IIRC and you SHOULD be able to connect and DVI cable between the card and monitor and then select 'DVI-D' on the monitor. If you're doing dual monitors, make sure you've enable the second monitor in the control panel once that is done.

I'm going to be doing dual monitors. I actually activated the second one with only this lcd plugged in. I switched to DVI-A mode and saw a picture, DVI-D was still black...

Are you sure I didn't get the wrong cable? I see there is a DVI-D connection that has a different pin configuration than the one I purchased.

No. DVI-I will carry a DVI-D connection. DCI-I carries BOTH. a DVI-D cable would not carry the analog signal.

Here's a bit of info with some pictures

Excellent FAQ. I new I had read that somewhere but I forgot it was @ blue jeans cable.

Yeah, I had no idea it was so complicated until I stumbled upon that page a few months ago. I'm a CRT guy

The middle 2 rows of pins are missing in mine, why is that?

thefish8: You've probably figured this out by now, but that indicates you have a single link cable:

Single Link DVI uses 12 of the available pins providing a maximum bandwidth of 165MHz. Single Link connectors do not use pins 4, 5, 12, 13, 20 and 21.

The dual link DVI cables incorporate all pins.

Good link. That should resolve any and all problems.
