I just got my new 23" cinema display, and this thing is HUGE and amazing... I do however have a slight issue that someone may be able to clear up... Whenever video is playing (i.e. a DVD or a screen saver), there is a vertical scan line thing that travels from the bottom of the display to the top about every two seconds or so, that seems to be "splitting" the video feed, like the video underneath that line is 2 or 3 frames behind the video above the line. Any ideas? Is this normal? It is really only noticeable when you look closely, but I work with video a lot so I notice stuff like that. Thanks in advance.
