I want to start out by saying I'd rather avoid third party programs like Dimmer, PangoBright, etc if possible. I don't think I need them, since I know my hardware is capable of what I want.
I have a tri-boot of Windows 10, Windows 7 and Ubuntu. In both Windows 10 and Ubuntu, I can get the screen very dim, so in a dark room I can barely see the keyboard. However, in Windows 7, the screen doesn't go nearly as dim; it's maybe 25% brighter at its minimum compared to the other OSes.
I know my screen can go dimmer than Windows 7 allows it, because it works on other OSes. It almost looks like Windows 7 has some arbitrary limit set somewhere that doesn't actually reflect my hardware's capabilities.
Is there some way I can adjust this lower limit in Windows, without using a screen overlay to "darken" the screen?
This is a laptop:
- MSI GP60 2QF
- NVIDIA 950m/Intel 4600
It did come with Windows 8.1, but the support page provides drivers for Windows 7 (which I have installed).
