[QUOTE="IWT, post: 1802475, member: 83420"] Firstly, let me extend a very warm welcome to our Forums. Secondly, I'm no expert in this area, but I should have thought that if there is no such problem on an external display, that would tend to rule out a Graphics Card problem and perhaps point to a linear pixel issue with your Mac's screen. But hold on till wiser counsel get a chance to offer better advice. Ian [/QUOTE]
