So I sold my 2 x 2Ghz G5 since my MBP was just as fast and used the money to purchase a 30" Cinema Display refurbished. All seems fine at first but I notice on black or dark screens I am getting horizontal pixel flashes at random. I have set up a replacement with Apple (I have noticed 3 dead pixels but that's minor). I have ran the video test in TechTool and the Video ram passes fine. The laptop also drives a 23" ACD no problem. Reading the forums though it seems this is common with the MBP? Anyone have a cause or solution? I had my MLB replaced for the whine (which is finally gone) a few weeks ago. I saw some reports of this on Macfixit.com but you have to 'subscribe' to read the article and I'm not paying 24.00 to read a forum. Help!!
