No HDMI AO722

I've been using my Acer One 722 for a couple of years now and I absolutely love it.  Yesterday, I tried the HDMI output for the first time.  Unfortunately, it didn't work.  When I plugged in the HDMI cable, the display on the notebook went blank and the TV showed "No Signal".  <Fn> + <F5> seems to do nothing.  <Fn> + <F6> turns the backlight on and off as it should. When I unpluig the HDMI cable the display stays blank.  Nothing I do brings back my Windows screen.  I need to power off and back on.

 

I've tested the cable and it's fine.  My other laptop works fine with the same cable.

 

I've updated the BIOS with no improvement.

 

Any suggestion?
