dual link DVI cards VS single link DVI cards question

ok, this is new to me. I still have a CRT tube for a monitor but am building a new pc.

Just noticed that there is a difference in cards with dual and single dvi outputs. it seems that if you use a dual dvi card, do you need 2 dvi connections on the LCD to get the maximum "The dual link DVI pins effectively double the power of transmission and provide an increase of speed and signal quality; i.e. a DVI single link 60-Hz LCD can display a resolution of 1920 x 1080, while a DVI dual link can display a resolution of 2048 x 1536."

this is new to me.

DVI is capable of 1920 X 1080. Dual Link DVI offers more bandwidth through a single cable like the Dell and Apple 30" LCDs (2048 x 1536). The 46" Samsung doesn't seem to have DVI but it has VGA or you could use component.
