I have had a horrible time trying to find an adapter that would work with my brother's computer. I could not find a cable that would connect the computer to the monitor so that I could work on it and pull off all of his photos he is editing. I tried a few other adapters to see if I could find one that would work with it, finally getting this one to add to the collection. It didn't work for me either. But this one DOES work with my projector, so I can easily connect other computers, devices, laptops, etc. and display them on my wall with the projector. It wasn't a total loss for me since it does work with other things and I can still use it, but it wasn't any help with getting access to my brother's pc.
