I have a new iMac for 2 moths.


This morning sudenly my Mac 27inch shows a horizontal dotted line (1 pixel), at the bottom of the screen: at 20% from the bottom.

That's a lot (20%) when you see it.

Below that line, the image starts to flicker now and then.

There is also a vertical yellow line accross the screen (1 pixel) on the left, also at about 20% from the right.


When I make a screen capture, the lines and flickering cannot be seen on the image or movie.


The flickering is very anoying, what can I do?
