    Samsung PM55H loses HDMI

    It works for a couple of minutes, but then goes off but the power stays on. This is a professional display, so it should be a better design.

    Are the backlights turning off? Turn the backlights down to 50% and see if they stay on longer.
    My bet is that the backlight setting is 100%.
