I just purchased a DVI cable from Blue Jeans (nice quality) for my new Samsung SIR-T451 receiver. I used component cables for the first couple weeks, and I was pleasantly surprised with the video quality using the DVI cable. There does seem to be a small improvement in terms of even sharper detail and color clarity, and the improvement seems even more apparent with SD programming. As best I can determine, outlines of objects are cleaner and more distinct. Am I possibly just imagining an improvement, or have others noticed a similar improvement using a DVI connection with CRTs ??? Based on what I have read here, I wasn't anticipating an improved image. The consensus seems to be that an improvement is only noticeable with digital displays (i.e. DLP & Plasma).
