Greetings,

I've just installed a Dell ST2410 monitor using the VGA cable that came with it(no DVI cable was present). I have heard that the monitor's performance will be enhanced by using DVI instead of VGA but I see that DVI comes in multiple flavors. The Dell monitor accepts DVI-D whereas it would seem that my NVIDIA 6800 GT card only accepts DVI-I, at least that's the way I read the specs on the graphics card.

My question then is: Is my monitor incompatible with my graphics card in terms of hooking the two up using DVI?

Thanks...

There is no conflict.
DVI-I accept broader spectrum. It's compatible with both DVI-D (digtal) and DVI-A (analog, same as VGA) signal.
The difference in picture quality depends on the quality of your video card.

I give you an example from my setup.
My desktop has top notch video card and it uses dual monitors. One is connected through DVI cable, the other one through VGA cable. Both monitors are same brand, same size and almost same model. Honestly, I see no difference in picture quality.

However, when I connect my laptop (average level, average on-board video chip) to one of the monitors through VGA cable, the quality is visibly worse.

Broni,

Thanks for the info. But one more small question: Should a buy a DVI-D DVI-I cable or does it simply not matter?

DVI-I will do.
