No HDMI output after upgrade to 16.04!

[EDEMPCO]

Running Ubuntu 16.04 64bit, 4.4.8 Kernel on an ASUS Trio with Intel® Haswell graphics card and using i915 driver. After upgrade there is no HDMI output to the external screen that I use daily.
I did the following:
- Upgraded to 4.4.8 Kernel hoping that the issue would be resolved.
- Checked for other reports of this issue and followed advise to use NVIDIA 364 drivers.
- Checked Intel for the most recent driver which is already packaged with 16.04; it is the i915 driver which is in use.
- Used Intel driver update tool to ensure that update is correct.
- Purchased a HDMI adapter to use mini-display port; works and reports HDMI1 is in use, but HDMI2 is not recognized (when monitor is plugged in to HDMI2)
- Someone has assisted and has confirmed that there seems to be no hardware issues.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

Thanks Brian for the suggestion.

Sorry, the only "package" that I can guess that it could be xorg. I have attempted to get help in the IRC chat at FreeNode, but instead I got just questions. I asked for assistance to identify a package name three times during a 30 minute session and got no help. So, I'm stuck.

If Ubuntu 16.04 includes the Intel driver and, I've insured that the driver is correct and, loaded using the Intel Graphics Tool and, checked the status above ... I don't know what else to do.
