[QUOTE="chscag, post: 1014692, member: 46727"] Before we can suggest something, you need to narrow down what's causing the vertical purple line. Attach another monitor or TV to your Mac. Does the purple line appear there also? If it does, it may indicate a problem with the graphics processor. If it doesn't appear, that would indicate it's the internal monitor display that has the problem. Regards. [/QUOTE]
