Thank you for joining the Intel communities.
Try accessing the Intel® HD Graphics Control panel and press <Ctrl><Alt>F8 to set your system graphics to defaults and see if that works.
Please be aware that scaling is available on the Intel graphics but we are still waiting for a Windows update in order to have it functioning as you can see here:
As well access the Intel® HD Graphics Control panel, click display and under general settings look down for the “Customize Aspect Ratio” option, select it and scroll the sides of the screen as it shows on the picture below.
Seems we have to wait for Windows update...
Your hints could not solve the problem...
Thank you :-)
