    I beg your pardon my English is terrible
    Hi, I have the triple screen and the image displayed on the three-projector. Images from the Projector go without distortion, but when connected to the first display is running Matrox MGA 2164W Millennium II from VNC, I can see horizontal lines across screen. When you connect to other screens, this error does not.

    And Information about system:
    # cat /etc/redhat-release
    CentOS release 5.8 (Final)

    # lspci -nn | grep VGA
