  1. There are two identical 19 inch monitors connected to a desktop. One is connected using dvi and the other using vga. One monitor works fine but the other has small resolution and doesn’t have settings for larger. So when I go to display properties settings the largest I can get on one monitor is 1024x768 and there’s no 1280x1024 for some reason. It use to work fine.

    when you connect both monitors to the same video card (via a Y-cable or dual ports)
    you expect both to use the same resolution.

    running one DVI and the other VGA?? Make sure the primary #1 monitor is attached to the
    DVI card.

    It has an onboared video card and the DVI uses an adapter to a display port.

    have you check your bios for any video configuration?
    Am also surprised that you managed to run a built-in video and a video card.

    Yes it use to work
    Yes monitors are connected to onboard video card
    No I haven't checked the bios settings, what should I look for?
