HDMI input not working on HP monitor

Had the psp3 connected to monitor with HDMI, working great. Power went out in house, now HDMI input not working, it does show signal in the display. Have used two different cords and tested both on another monitor, both worked ...????

If the monitor does not work in a different computer, the monitor is bad.
