Make sure you have both monitor hook up - I do not and could not complete setup until I do . I have a old clunker w3050 e-machine and can now stream netflix to my 42 inch flat screen ! that be all I want . what be really cool be I can hold the mouse down and move anything I be do from screen to screen . I can play Farmville on my 42 inch if I want . I would have have it hook up in no time but I do not have both the tv and the monitor hook up . I figure I would do that after I get it work . I could not get it work until I hook both up and restart my pc . so do it that way and do not sit and cuss for 3 hour like I do . also-i wish I would have know that older computer have different slot ! GOOGLE you computer and make sure you know what kind of slot you have ! older one have only PCI . if you be newer it may have pci-e this be a agp . if you do not know what I be talk about then you , be a idiot like I ! that why I have a $ 50 dollar pci-e card sit here collect dust ! Know you slot and do not try fitting a round peg into a square hole ! this card work perfect if you have the slot for it .
