I have a bfg 7800gt oc and plan on ordering a Samsung 940b from newegg this week, which from the reviews doesnt come with the dvi cable. i was hoping to save on the $5 shipping for the cable so I went to radio shack. They carry a dvi-d single link and a dvi-i dual link. I picked up the dvi-i 12 ft. for $12.49 because I figured the ability to carry an analog signal also would be good.

Poking around the internet tonight I came across something that said if your monitor and video card both support digital signal than use the dvi-d cable so only a digital signal will be used. Even though my video card has a dvi-i connector, I think I will switch to the dvi-d cable, for the above reason and the fact that the monitor specifications on newegg list dvi digital, which means the dvi-i cable wouldnt even plug in. OK, on to my main question.

In order to save the shipping and get the cable from Radio Shack I would have to go with the single link, as they dont carry a dvi-d dual link, which is what newegg carries.
I found this on the net:

The dual link effectively doubles the power of transmission and provides an increase of speed and signal quality; i.e. a single link 60-Hz LCD can display a resolution of 1920 x 1080 (enough for HDTV) , while a dual link can display a resolution of 2048 x 1536. There is some confusion as to 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

Since the Samsung has a resolution of 1280x1024, I think I'll get the single link dvi-d from radio shack (which has gold connectors). Just looking for reassurance that I dont need the dual link dvi-d from newegg for $6 more.

Thanks for bearing with me here. I know its only a $12 part but I get a little anal over trying to undertand things and make the right decisions, and I was afraid that a single link cable would have an inferior picture.

All of this because Samsung wanted to save a few dollars and not include the cable.

thanks a bunch guys
