[QUOTE="chscag, post: 1653136, member: 46727"] You need to test your machine to see if it's the graphics adapter or something else. The best way to do that is to attach an external monitor or TV. If it does the same thing, it may be the graphics adapter. Also, when you post a question to a forum you should include your Mac (year and model) and what version of OS X it's running. This is so we can better answer your questions. [/QUOTE]
