When you say "didn't work", do you mean it didn't fix the issue or did the installation fail?
In the latter case try drivers from this list Downloads for Intel® HD Graphics 5500
Select OS from right pulldown menu. Hit show more.
If you encounter an error message about validation, then install driver via "have disk method" as described at:
(ignore prolog about MS surface)
I suggest to upload a report from Intel® System Support Utility for Windows* so an Intel agent can take a look at it after the holidays.
Also you can ask at community.acer.com for further help.
btw do the distortions also appear on an external monitor or TV?
