    4th Monitor not recognised

    I have had 3 monitors connected for years and finally connected a fourth. Windows (8) will sort of detect it but not completely.
    In where I change appearance of displays 1,2,3 are detected. 4 has a little window saying "display not detected", but it is in fact detected or that little window saying "display not detected" would not be there.
    2 Monitors (1 and 2) are off the motherboard, 3 and 4 are off a pci card.
    The one that does not work is connected to the DVI port on the card.
    I have re installed the pci video card software again, but makes no difference
    Suggestions please

    Post the make and model of the video card you are using. I did not see it in your signature.

    Does the monitor have a DVI port/cable that you are using to connect it to the card, or are you using a DVI to VGA adapter.

    If one of your monitors has a DVI connection and cable, try that one on the DVI port. If it works, then the adapter may be the problem.
