I'm trying to use an external display with my MacBook Pro laptop. The laptop detects the display and the display is running at its native resolution of 1680 by 1050.
However, there are constant green pixels randomly flashing on and off evenly across the entire display area.
The display is connected via a mini DVI to HDMI adaptor.
I tried power cycling everything.
I also verified that this display works fine with a different MacBook Pro -- a much older one with the old HDMI out port.
Is anyone else seeing this problem?
Is there any way to fix it?
