Acer laptop HDMI not working with Windows 10

I just upgraded to Windows 10 from 7. My external Acer monitor (G276HL) was working fine with my Acer laptop(Aspire 7745G) with Windows 7. With Windows 10 the external monitor does not get a signal via the HDMI port. I switched to a VGA hookup and this
allowed me to use my external monitor. Why does the HDMI hookup no longer work?

After installing Technical Preview my Acer monitor is not detected when plugged in by VGA to Lenovo G500 laptop. This works on the 7 Dual Boot.

I only see one Generic Monitor detected in Dev Mgr. All Devices were issued drivers at install.
