this product do what it say . I get it for work purpose so that I do not have to keep splitting the screen to compare document side by side . I now be able to view 1 document on each screen and drag and drop any window that I have open between the two screen . the only downside be that the monitor that I have run off this adapter have funky color , depend what be on the screen . anything that be light blue will show up as a bright aqua color . also another thing I notice be there be a tiny delay on anything I be viewing\/moving on this same monitor . keep in mind I be use a older flat screen monitor , which could be the reason for the color change -lrb- I 'll update my review once this monitor die -rrb- . also the delay might be from the RAM or something . the desktop computer I use at work be a few year old . but I do love it and the ease of hook it up . and I love that it do what it say . I would give 5 star if not for the color problem and delay .
