I have a macbook pro 15 inch with thunderbolt and osx lion and a imac 24 inch. Now i went to an apple store and ask them if i could connect my macbook to my imac, they said just 'no' and they gave me no other solution... nice service haha. What I want is that when i arrive home i just want to work on the big screen by simply connect the macbook to the imac. I'm considering to sell my imac and buy a 27 inch screen, but an apple screen costs 999 euro while i can get an HP 27 inch screen for just 340 euro. But my 2 questions are the next: can i connect the macbook to a different screen than an apple screen what would you do?
