Ok so guys couple of weeks back I purchased a DELL 24" monitor..I got it for about 180$? and for it was a good deal, so I proceeded to by a DVI-D connection from my mac to DVI-D to my new minitor. (Please note I do not own a uni-body since I'm still using my old MBP and see point in buying a new one that has the MiniDisplay Port on it) So right now I have the connections going and I have my MBP lid closed, so everything is displaying on my new screen only (no duel screen!) here is my question 1) Will there major over heating issues? 2) Am I reducing my MBP's life by making it display on an external screen that was not made by Apple (Cinema Display) 3) Suggestions from anyone who is doing this to make performance better Thank you in advance folks, Cheers!
