There is no analog to digital conversion since if the laptop supports DVI pass through, then the DVI is sent directly to the port in the replicator or docking station.
I've used IBM's, HP's, and currently a Dell M60 that all support DVI pass through. You need to check carefully, because some models do NOT support DVI pass through, for example, the IBM T41p and R50p support DVI pass through, but the T41 and R50 do not. Also, make sure you check on the supported resolutions because some do not support resolutions higher than 1280 X 1024. The IBM's only go up to 1280 X 1024. (Big complaint of mine.) The Dell and HP support up to 1600 X 1200.
