Unlike many, i have the requisite card and cords. this adapter worked 1 time for me to test it for five minutes. I tried again two days later, and nada. garbled crap for signal the second time i tried it, cant even make out pictures words or anything. It is not a problem with my card or computer as numerous other adapters still work with it (and yes of the same dvi style). This is without a doubt, the worst adapter i have ever worked with. do NOT buy this product.
