What is going to be the difference. I see the monitor I got has a DVI-D Single Link cable. Is this like running 1080i instead of running 1080p with dua link cablel?

So now I see there is a DVI-DL (dual link) cable. This is cable with additional pins in it making it a DL and not a single. Question is does the monitor support DVI-DL? I looked @ the specs of the monitor and doesn't say thing about DVI-DL.

Also what would differences look like?

Its to do with the rez your using

Single up to 1920 × 1200
Dual up to 2560 × 1600

so even for 1080p singlelink will do
