I have recently brought this adapter to connect my Macbook with my projector. I had the projector before run on my old VGA adapter, the time I had with my Macbook (late 08) ordered through Apple. Never had problems so I just the picture was not quite so great, as it was now times the VGA port. I wanted now but look also HD movies in full quality and am therefore switched to HDMI. The picture is also top and without any blemish. The audio transmission has not always interested me because I control everything directly through the Mac and this eh still does not sound transmission through MDP. So far so good, but now comes the big hook for me. I use the projector also in order to surf the Internet and here denied the adapter to full line. I do not know how he does it, but he completely hampered the Wifi reception of my computer. After I plugged the adapter is almost nothing once I have removed him running again everything perfectly. The adapter also raises small spark when he touches the DisplayPort, do not do my ORIGINAL adapter. In addition, it cracks and unhealthy in the cable when you move it somehow (slightly buckled). All in all, the adapter on the first impression a good picture, but looks can be deceiving. It may be of course now that I've caught "rotten egg", especially with the good reviews of other users, but for me it is clear that I what can not use so and I will as soon claim as possible and send it back, let's see what the provider has to say and whether the replacement device but still keeps its promises. So I must, however, advise against umbedingt purchase and recommend a different product, but it should prove to be a particular case, I'll mention it in this review yet, and this perspective.
