Summary: Very laggy, flickers and does not even show some content. iPhoto and some videos just throw up a black screen. But as a third monitor dedicated to displaying my to-do list, Finder and taking notes, it's totally sufficient. Just don't expect this to display anything heavier than that.
Summary: While I love having the extra monitor to use while standing, this product has one minor glitch. It was easy to install and get the second monitor up and running. However, be aware that occasionally, your screen will 'black out' for a few seconds.
