    Hello,

    I am trying to get dual monitors working using a Sony Vaio docking station. I've connected one monitor using VGA port, which is simple enough.

    Problem I'm having is with the DVI-D port for the second monitor. If I have a monitor with a DVI-I port will this work with the DVI-D port on the docking station? If so, what cable(s)/adaptors will I need?? I read that you cannot connect a DVI-I cable to a DVI-D port (only DVI-D cable to DVI-I port), if so is there an adaptor available?? [​IMG]

    Thanks in advance.

    Tim

    Hi Tim and welcome to TSG.

    The DVI-I input port on the monitor means that it can support both (not at same time) analog and digital video signals. The DVI-D output port on the dock means that it can only support a digital video output. A cable with DVI-D plugs at both ends should work to feed digital video to the monitor. You would just need to determine if you need a single or dual link DVI-D cable.

    A dual-link cable is not for driving two monitors. It is for driving a single monitor whose resolution and refresh rate exceeds the maximum data rate for a single set of serial digital lines. A second set of lines is used to double the available bandwidth.

    The cable in your link is shown as a dual link cable. Double check the pinout of the connector in the photo and compare that to the DVI jacks on both the dock and monitor. If either jack may block a cluster of pins, then you need a single link cable. The following link is for a DVI-D single link cable on the Misco site. The plug diagrams show the missing cluster of pins.
