  1. Dual display problem

    I have just finished updating to mavericks but am having a slight problem. I have a gigabyte z77n motherboard and use hd 4000 integrated graphics. One hdmi is connected to a monitor and the other hdmi to a tv. When only one is connected everything is fine but when I connect the second hdmi the screens go crazy. The image splits and is made of horizontal lines. Any ideas on how to fix this?
