Well built adaptor but it does not work with Mac Pro' s (Early 2009) DVI-D connection. I do not know if it is a setting but when I used a mini display to VGA adapter it worked perfectly. Fortunately I had this option, otherwise I would not be able to boot up my computer.
I read the reviews. the people saying it doesnt work. I thought perhaps it might work on my system, It doesnt. I have an LCD Monitor that's about 8 years old. It has the right number of pins, it fits in the port, but it does not do what its supposed to. Save yourself the time and money and just get one where most of the reviews say it works, and not buy a cheap bit of rubbish and hope for the best.
The customer support was very good. When the first item did not arrive another was promptly dispatched.
Unfortunately the adaptor did not work at all with my graphics card. The customer support says they've had problems with Radeon and HP graphics cards, so if that applies you, this product is not for you.
