I always contemplated weather or not to buy one of these mini display port to hdmi video adapter because my macbook is always full of films which I wanted to enjoy on my 32 full hd led television. I therefore decided that I should buy one, what a brilliant decision!
I never found it so much easier to connect your laptop to the tv all you do is connect the hdmi cable to the display port and straight into your laptop. The quality of your fill still remains what it was originally and 1080 dpi bluray movies can be seen on a much bigger screen.
I found the product to be very small and easily transportable. I travel a lot and i can easily bring it with me. I did find that i had to bring the hdmi cable with me but i really don't mind doing that. When travelling I attach my laptop to the computer and I can enjoy the big screen which strains your eyes less.
I also use this device when wanting to have two screens at the same time, so i can have my itunes playlist and be doing my office work at the same time.
I think that for the price this is one useful gadget that all mac users should have, I really enjoy it and I am sure you will too!
