I've also hooked up many monitors over the years and found any accompanying CD's totally worthless. They either contained duplicate instructions (if there were any in the box to begin with) or how-to-connect gibberish that wasn't needed. HOWEVER, I recently acquired a new 23" Samsung widescreen that came with a Magic Tune CD to permit on-screen monitor adjustments using the mouse. I thought that would be pretty cool until discovering that the CD wouldn't work on Windows 7 64 bit machines! I was, however, able to download the 64-bit version from their website that works perfectly. So … maybe a monitor's CD might be useful if it actually does something useful and works on your machine!
