=== Problem Description ===

No matter what settings you choose for your display in Intel HD Graphics Control Panel -> Display -> Basic -> Scaling,

When you launch a fullscreen application the setting will be ignored and it will revert back to 'constrain propostions' when enabling fullscreen, then when you alt-tab to desktop it will go back to your selected mode, then you alt tab to game and it will go back to proportions setting again, making it impossible to get rid of the black borders.

The setting only is applicable in Windows 10 Desktop, doesn't work for fullscreen apps.

It worked good in Windows 8.1, I just upgraded from 8.1 to 10.

In windows 8.1 I could game on any resolution without black borders - a nice, full, filled screen.

I think I have the same issue as the sir here:

Please fix this ASAP or suggest steps to fix.

Problem does not happen without drivers (Driverless) -> Games run in full screen / fill screen mode at any resolution (so this is not a Windows bug).
