How to freeze multiple monitors RRS feed

  • Question

  • Hi, we have developed a ophthalmic device that contains a single board computer which runs professional Windows 7. It has a large external monitor to be used by the nurse, and a patient screen which is a tiny OLED screen with very low resolution, built inside the device, which patient looks at through some optics. We show figures such as the acuity characters on this tiny OLED screen, and we show the main user interface on the large external monitor.

    The problem is: if someone accidentally boots up the device without connecting the large external monitor, Windows automatically shifts to the tiny OLED screen. Everything became cranked up. Even if we reconnect the large external monitor it wouldn't go back.

    Can we lock up/freeze up the monitors, so that no matter what happens, Windows always stays on the large monitor and the acuity screen is always on the small monitor?
