I have just received my Adapter so I can run Dual Monitors on my MacBook Pro (Purchased February 2011)

Adapter shown here:


Despite it saying Air I don't think that is a problem as it's the port type and adapter type that matter...

So yes, I have plugged it in, however... Once plugged in, My MacBook Pro blinks a couple of times then comes up blue screen... and the Monitor comes on also with same color of screen.

However no mouse or visuals that I can work with to configure it with.

How exactly do I set up Dual Monitors on my Mac?

(I'm on OS X Lion now)

Fails... monitor and mac constantly blink from blue screen to actual screen it should be displaying....

I can set it to lower resolution very slowly but it still does the same thing =/

Best answer is:

Don't get a MacBook Pro if intending to link up for Dual screens. It's been an ongoing problem since 2009. People have had the problem since then till this very day... forums say it all.

I'm rather quite sick and tired of Mac's lack of ability to announce when they will fix problems that is known world wide... wifi's on lion going down and not working and displayport not working.

These are factory hardware needs, yet they don't work.

I agree. I bought an iMac, i5 27" that I paid a fortune for. The cheap ass 1TB Seagate HDD makes a stomach grumbling noise that was well described in over a hundred forum pages. Still, it took Apple over a year to address the problem.
