HDMI to DVI Adapter info

Hey everyone! I was just wondering, that because my video card supports an HDMI output but my LCD is the only thing stopping it, will buying an HDMI to DVI adapter like http://www.hdtvsupply.com/dvca.html help improve graphics? I was wondering because I have two HDMI cables lying around. I use one of them to connect my laptop to an LCD TV whenever needed so i dont need the other one. I can afford one of the adapters BUT before I go out there and buy it, I want YOUR advice and experience suggesting if it will make any difference the in the picture quality. I use a vx1940w LCD with 1680x1050 resolution.
