at the moment of writing, PC is running with factory setting but it's all up-to-date (Windows updates, Asus updates).
When I launch an app (emulators, in the specific case) at full screen, only the 60% (approx.) of the left side of the screen is showing correctly when using Direct3D graphics option.
I partially 'solved' this by switching to OpenGL but those apps that don't have this option won't run correctly.
I've also tried running them in compatibility mode and disabling DPI switch.

Running on an ASUS T101HA-GRD43T with a built-in Intel(R) HD graphics card

Any suggestions?
